Invoke src/main.py as a module with python -m src.main which will add the top-level directory to the python path. from setuptools import setup, find_packages from pathlib import Path import os directory = --entry_points , 1 # The entries here should be a simple duplicate of those in the collaborator, ';platform_system=="Linux" and (platform_machine=="arm64" or ', # If this is a collaborator build, then build an "installer" wheel and. [PyPI](https://badge.fury.io/py/tensorflow.svg)](https://badge.fury.io/py/tensorflow), TensorFlow is an open source software library for high performance numerical, computation. ,IP,,, 1.1:1 2.VIPC, AppWebAppAppAppAppAppbug, 1. Do we need to do that, and how to do it? If we remove the. Each subdirectory of src is usually a git repository containing one or more package. A typical project layout for an executable may look like the following, which includes C++ source codes and a build file, CMakeLists.txt if using CMake. # Copy external code headers into tensorflow/include. packagespackagepackage setup(packages=['src','src.pack1','src.pack1.data']); setuptoolsfind_namespace_packages,find_packagespackage. Open Python (type python into your terminal window), and type. Basically, pyright recognise the pyproject.toml inside the foo/bar folder as a module instead of foo/bar/bar, so when it resolves import bar, it's looking at foo/bar and not foo/bar/bar. author="ctgk", --find_packages() packagessetup.py __init__.py srcaaa.txtdata The setup.cfg is written in a different format compared to setup.py, and contains basically two essential keys, command and options. The cython command takes a .py or .pyx file and compiles it into a C/C++ file. Assuming the contents of the files are the following: For this C++ program, we need to compile and build its code. Putting it directly into src/mypackage worked like a charm. Note that find_package (pybind11) will only work correctly if pybind11 has been correctly installed on the system, e. g. after downloading or cloning the pybind11 repository : # Classic CMake cd pybind11 mkdir build cd build cmake .. make install # CMake 3.15+ cd pybind11 cmake -S . The options are passed unmodified, and presently offer direct access to the distutils command line. Once our project has the setup.py file, our package is ready to distribute and install. TensorFlow is licensed under [Apache. :pack|---src| - common ---http ---user| - lib| - factory.py2. # See https://github.com/tensorflow/tensorflow/issues/17882. __name__ is an attribute every Python module has, and it is the string that a module uses to identify itself. The package approach helps us organize Python code well and well structure Python modules namespaces by avoiding naming collisions between modules. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. @amirhm I already did this, they were deleted after running pip install. Why is python setup.py saying invalid command 'bdist_wheel' on Travis CI? Protobuf Therefore, every .py file is a module; a Python script is also a module. Not the answer you're looking for? which lets you change your source code (both tests and application) and rerun tests at will. Since its Python, compiler the code is not necessary. find_packages(exclude=[".tests", ".tests. cd /project/src python some_file.py --accelerator 'gpu'--devices 8--strategy 'ddp' Distributed Data Parallel in Notebooks DDP Notebook/Fork is an alternative to Spawn that can be used in interactive Python and Jupyter notebooks, Google Colab, Kaggle notebooks, and so on: The Trainer enables it by default when such environments are detected. This is the only directory containing files that you edit. Python person_pb2.py Protobuf. Connect and share knowledge within a single location that is structured and easy to search. One important thing to be aware of in the previous examples is that we add the if __name__ == __main__ statement in the mylib.py module. The first step towards sharing a Python library or program is to build a distribution package [1].This includes adding a set of additional files containing metadata and configuration to not only instruct setuptools on how the distribution should be built but also to help installer (such as pip) during the installation process. Our package works as expected. A simple package example could look like the following: One package can contain another package; one package can also consist of multiple packages and modules. ", "tests. I suggest studying the pre-built scripts to make your own setup.py. # NOTE(keveman): Figure out how to customize bdist_wheel package so, 'tensorflow/include/external/eigen_archive/', 'tensorflow/include/external/com_google_absl/', """Return all the files matching pattern below root dir. Our package works as expected. As mentioned above, we use the -m option with the package name to execute a package directly. Does Python have a ternary conditional operator? One of the locations should end with python3.7/site-packages . Please have in mind that find_namespace: (setup.cfg), find_namespace_packages() (setup.py) and find (pyproject.toml) will scan all folders that you have in your project directory if you use a flat-layout. Conventions for Python test discovery pytest implements the following standard test discovery: Enter the account credentials you registered for on the actual PyPI. The code for setup.py is: Thanks for contributing an answer to Stack Overflow! description="Collection of PRML algorithms", But there is more. # TensorBoard command, pip will inappropriately remove it during install. For tf_nightly, we install the nightly, # variant of each package instead, which must be one version ahead of the, # current release version. egg, demomkdir demodemoinit.py, eggpythondist-packages, setup()eggprojectsetup(), find_packages() In C++, we need to decide if we want to build an executable or a library, but the boundary between an executable and a library in Python is blurred. Its like main(), the entry point in a C++ program. Connect and share knowledge within a single location that is structured and easy to search. setup.py **pythonpip install python setup.py installpythonpip psutilhttp://code.google.com/p/psutil/CPUpstoplsofnetstatifconfigwhodfkillfreeniceio https://www.cnblogs.com/smileyes/p/7288487.html https://blog.csdn.net/feng973/article/details/78835453 https://www.linuxidc.com/Linux/2017-02/140234.htmhttp://blog.chin So it is working so far. intree_extension will automatically detect if you are using a src -style layout (as long as no namespace packages are involved), but you can also explicitly pass package_dir to it (as in setuptools.setup ). python_requires=">=3.6", Help us identify new roles for community members, Proposing a Community-Specific Closure Reason for non-English content. To review, open the file in an editor that reveals hidden Unicode characters. 0.0.0.0/0, jainkai: Is this an at-all realistic configuration for a DHC-2 Beaver? With late versions of pip, projects without setup.py may be installed in this mode. I generated the manifest file to include the *.pyd files from setup.py based on the environmental path from the installation. Although the setup.py file is mainly for defining what we want the project to be built, distributed, and installed, the setup file is just a regular Python file, so that we can use any Python functionality in the setup file. For example: Linux. *"]), # package,find_packages packageexclude But we need the files to be in a specific directory. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. And assuming the content of the cli.py is the following: We use the entry_points option in the setup.py file to define the entry: In the code snippet above, the keyword console_scripts indicates the entry is console type, and console_scripts expects a list of console scripts. from setuptools import setup, find_packages from pathlib import Path import os directory = To learn more, see our tips on writing great answers. Is it possible to exclude data file sources and intermediary files from bdist? , https://setuptools.readthedocs.io/en/latest/setuptools.html. Importing a package as a library is the same as importing a module. These arguments are included in the command as follows: python setup.py

In other words, its the modules name when executing it. setuptoolsPython distutilsPythonsetuptoolssetuptools, python setup.py bdist_eggtest, setup(), 3. In this talk we will talk about the challenges we faced when managing Apache Airflow dependencies at scale. Building a C++ library is similar to a C++ executable project, which also needs C++ code and a build file. The following example demonstrates how it works with a package. # These are all updated during the TF release process. When I started learning Python, I thought Python was a scripting language and could only be running as a script. which lets you change your source code (both tests and application) and rerun tests at will. --classifiers of your package. In this talk we will talk about the challenges we faced when managing Apache Airflow dependencies at scale. Following the previous article, Development Environment Setup and Virtual Environment, this article does not discuss language differences, but focuses on project build and its usage. $ python -m pip wheel --global-option bdist_ext --global-option -DFOO wheel. Putting it directly into src/mypackage worked like a charm. If a package follows a, # different versioning scheme (e.g., PVP), we use different bound specifier and, # TODO(b/213222745) gast versions above 0.4.0 break TF's tests, # TODO(b/239052279): replace with external dependency on JAX repo once JAX, # TODO(b/182876485): Protobuf 3.20 results in linker errors on Windows. """TensorFlow is an open source machine learning framework for everyone. The cythonize command takes a .py or .pyx file and compiles it into a C/C++ file. Asking for help, clarification, or responding to other answers. With the understanding of __name__ and __main__, we can explain why we use the if __name__ == __main__ statement in the mylib.py module and how it prevents executing code when importing: the code under the if-statement block will be running only when the module is executed as the top-level code. We can also remove its .py extension to make it look like a shell script, which still works. It includes some advanced patterns and best practices for setup.py, as well as some commentedout nicetohaves. I wish someone could tell me how to do that using the concept or language I was already familiar with when I started learning Python. This simplifies the configuration and is more obvious to users who install the package. # add the collaborator packages as the only dependencies. I am a software engineer and a Christian. --scripts Besides, __name__ is a global variable inside a module and an attribute outside of the module. Is it appropriate to ignore emails from a student asking obvious questions? The first step towards sharing a Python library or program is to build a distribution package [1].This includes adding a set of additional files containing metadata and configuration to not only instruct setuptools on how the distribution should be built but also to help installer (such as pip) during the installation process. There are several files that are commonly included in the root folder of a Python project. Compiling from the command line . #4. packagessetup.pyinit.pysrcaaa.txtdata, setuptoolsinit.pyeggsetup.py. After we build the library project, libmylib.a will be generated, and our code can use it by including its header file and linking against the library. Assuming we have a Python module called mylib.py with the following content: The first way is to use the Python interpreter with the modules file name, like running a script (i.e., python mylib.py). # data.dat package_dir = {'':'src'}, Will add my files, but I think its hard to understand without everything else. And outside the mypackage package, we have a main.py that we want to import the module and use like a library. # accomodate as many pre-installed packages as possible. '':['.txt'], But this is a conceptual difference; we can still import a Python script. In other words, it can be accessed within or outside the module. The exclude_package_data option is a dictionary mapping package names to lists of wildcard patterns, just like the package_data option. --data_files Lets start with the src folder: it should contain three files, namely __init__.py, logic.py, and main.py. I can imagine there is a way of getting this to work from the command line. __main__ is the name of the environment where the top-level code runs. rev2022.12.11.43106. ), This article, along with any associated source code and files, is licensed under The Code Project Open License (CPOL), Various ways to run and build Python code for those who have C++ background.

The site packages folder is where all of your installed packages for a particular environment are located. I generated the manifest file to include the *.pyd files from setup.py based on the environmental path from the installation. The 3.x mode is intended to work with various scripts such as buildWinDists.bat for Windows, buildMacDist.sh for MacOS, and buildLinuxDist.sh for Ubuntu. The answer is yes, but in a different way. make && make installpython setup.py build && python setup.py install . # We exclude it anyway if building tf_nightly. These also usually have "alpha" or "dev" in their. In C++, we use CMakeLists.txt, Makefile, or something similar to define the build and installation process. The relationship between the setup.py file and the build tools is similar to CMakeLists.txt to CMake. Besides, by adding shebang, #!/usr/bin/env python, at the top of our script, the Python script can be executed as a shell script in a Linux system. Please migrate to %s for GPU support. Open Python (type python into your terminal window), and type. Python modules and packages can be imported as a library and executed as an executable. Note toward the end of the output, the lines starting with "Wrote:" indicate where the binary RPMs were written. hierarchy for -I to work correctly. The main difference is that we need to build the code as a library via the build tool, like CMake, so we define that in CMakeLists.txt to tell the compiler how to build the project as a library (the example below assumes we build a static library). Assuming we have a project with the layout shown below and a setup.py file which should be outside the package (mypackage in this example). The package name will be the name we specify in the setuptools.setup() function (e.g., /lib/python3.7/site-packages/my-package). If you have a version of pip older than v21.1 or is using a different packaging-related tool that does not support PEP 660, you might need to keep a setup.py file in file in your repository if you want to use editable installs. as a CSDNpython lxml python lxml python CSDN This is the only directory containing files that you edit. --find_packages() packagessetup.py init.py When a module is imported, its __name__ is the module name (i.e., the .py files filename without .py). wheel python setup.py sdist bdist_wheel ', 'toco_from_protos = tensorflow.lite.toco.python.toco_from_protos:main', 'tflite_convert = tensorflow.lite.python.tflite_convert:main', 'toco = tensorflow.lite.python.tflite_convert:main', 'saved_model_cli = tensorflow.python.tools.saved_model_cli:main', 'import_pb_to_tensorboard = tensorflow.python.tools.import_pb_to_tensorboard:main', # We need to keep the TensorBoard command, even though the console script, # is now declared by the tensorboard pip package. I'm trying to make a python c++ extension using setuptools and I'm using glfw in my c++ project. Therefore, we can use it by printing the value to demonstrate how a modules __main__ is assigned when imported and executed. The flexibility allows a Python package that contains both modules to be imported and modules to be executed in one package. Note that #!/usr/bin/env python specifies the path to the Python interpreter using the env command, which will execute the Python interpreter by looking at the PATH environment variable. *** ). setup.py setup.cfg [aliases] test=pytest test pytest python setup.py test python setup.py pytest setup.py $ python -m pip wheel --global-option bdist_ext --global-option -DFOO wheel. That is, if the package is built using setup.py it's fine, but note that you still can't have pyproject.toml file there even when used with setup.py. The command key represents one of the distutils commands, while the options key defines the options the command can support. In src/main.py modify sys.path to include the top-level directory. srcaaa.txtdata setup.pyPythonmake. The site packages folder is where all of your installed packages for a particular environment are located. My python project is laid out as follows: First, we write the python code, say in a file web_interface.py. And thats the purpose of this article. For each console entry, the format is =. --requires Would salt mines, lakes or flats be reasonably found in high, snowy elevations? install base library (C, C++); directories linked in the environment variables; here are also the *.pyd files. # A symlink would do, but the wheel file that gets created ignores. 4. Like Python modules, Python packages can be imported as a library or invoked as an executable. __init__.py is required to import the directory as a package, and should be empty. The PyPI package acapy-mydata-did-protocol receives a total of 467 downloads a week. Using this if-statement is to prevent executing code when importing the code as a module. setup.py. Although the setup.py file is mainly for defining what we want the project to be built, distributed, and installed, the setup file is just a regular Python file, so that we can use any Python functionality in the setup file. In this example, the main() function is the entry point, and its console script name is my-cli. --packages __init__.py-------setup.py init.py 3. Python packaging with setup.py does ignore manifest specifications. 'tensorboard = tensorboard.main:run_main', 'tf_upgrade_v2 = tensorflow.tools.compatibility.tf_upgrade_v2_main:main', 'tensorflow_estimator.python.estimator.tools.checkpoint_converter:main', """Override the dir where the headers go. Catkin uses workspaces to find your packages Calling catkin_make in the workspace builds it A catkin workspace consists of four sub-directories src This is the directory with all of your packages. # For pip, we will remove all '-' characters from this string, and use the, # Also update tensorflow/tensorflow.bzl and, # We use the same setup.py for all tensorflow_* packages and for the nightly, # equivalents (tf_nightly_*). --py_modules python packages=find_packages(exclude=["test", "test. The basic setup.py definition for the package looks like the following (the following examples use setuptools as the build tool). I want a script to import a module from another directory. Enter the account credentials you registered for on the actual PyPI. Python code can be built and run as a library or an executable like C++ and many other languages. Package structure and distribution. Q&A for work. I have a situation that I believe is relatively common. Copy Besides, each folder has an __init__.py file. MacOS Windows. error: no commands supplied distutils.errors.DistutilsArgError: no commands supplied During handling of the above exception, another exception occurred: File "C:\Users\DELL\Downloads\cashflower-main\tutorials\setup.py", line 8, in setup( SystemExit: usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ] or: psutil1. How can I make pip install package data (a config file)? --license Because we assume our main.py is in the same location as mypackage, the import path becomes mypackage.mylibrary as the code snippet shows below: (See python_package_library_example for the complete example.). The same mylib.py module can also be imported as a library. example.py is an example of a module within the package that could contain the logic (functions, classes, constants, etc.) The previous section shows what we usually do in C++. / setup.py src/ __init__.py foo.py bar.py an appropriate setup script would be from distutils.core import setup setup(name='foobar', version='1.0', package_dir={'foobar': 'src'}, packages=['foobar'], ) Or, you might put modules from your main package right in the distribution root: / setup.py __init__.py foo.py bar.py setup( These are: setup.py; readme.md; requirements.txt; __init__.py; License; Almost all projects benefit from these files from one way or another and it can even be said that they are necessary for packaging a Python library. This will give a list of locations python looks for packages when you do an import. For example: Linux. Each subdirectory of src is usually a git repository containing one or more package. That would make the learning process much more straightforward. you could add the files to be included in package_data, here *.pyd or specific file if you are interested. 'tensorflow_estimator >= 2.11.0rc0, < 2.12', # The depedencies here below are not actually used but are needed for, # package managers like poetry to parse as they are confused by the. The cython command takes a .py or .pyx file and compiles it into a C/C++ file. View setup.py from CS 5432 at University of Minnesota-Twin Cities. Once it is compiled and built, an executable binary, myexe, will be generated. The __init__.py files are required to make Python treat directories containing the file as packages (See Regular packages for the details). Run twine upload dist/* in the terminal/command line. This example uses both features; to only use SCM metadata for the version, replace the call to find_packages () with your manual package list, or to only use the package finder, remove use_scm_version=True. As such, we scored acapy-mydata-did-protocol popularity level to be Limited. 'test':['data/.dat'], We do not currently allow content pasted from ChatGPT on Stack Overflow; read our policy here.

", "tests"]) And then, we can run it by issuing ./myexe if we run the code in Linux. Should teachers encourage good students to help weaker ones? The following example will show different ways to run a Python module. Having them can actually be misleading as it causes the creation of package namespaces in each folder containing an init file, as described here.. By removing all those __init__.py files you will be able to import files in the namespace package (including Most of the time, __init__.py can be just an empty file. # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. View setup.py from CS 5432 at University of Minnesota-Twin Cities. In C++, we have header and CPP files, but in Python, there is only one type, .py files. The PyPI package acapy-mydata-did-protocol receives a total of 467 downloads a week. You signed in with another tab or window. The file used to define the process is called setup.py. packages These arguments are included in the command as follows: python setup.py BUILD COMMAND . [! Run twine upload dist/* in the terminal/command line. This example uses both features; to only use SCM metadata for the version, replace the call to find_packages () with your manual package list, or to only use the package finder, remove use_scm_version=True. Assuming we have a Python script named script.py with the following content: Running it as a script can be as easy as the following: The Python interpreter will execute the script from the top to the end. Simply download one of the .src.rpm files below, and run "rpmbuild --rebuild python-.src.rpm". pip python setup.py python setup.py , setup [Python](https://img.shields.io/pypi/pyversions/tensorflow.svg?style=plastic)](https://badge.fury.io/py/tensorflow), [! from setuptools import find_packages: from setuptools import setup: from setuptools. As explained in the nixpkgs manual, it uses the widely used `setup.py` file in order to package properly the application. Usually, the module name is the Python file without the .py extension. test_suite="test" The setuptools.setup() function is the function where we input our definition for package build, and calling the function is actually all we need to do in the setup file. EASY-INSTALL-ENTRY-SCRIPT: 'my-package==0.0.1','console_scripts','my-cli', Development Environment Setup and Virtual Environment, https://shunsvineyard.info/2022/10/08/python-vs-c-series-build-and-run, -- There are no messages in this forum --. The process for the user is supposed to be: But there are no *.pyd files in the module. Top-level code is the first user-specified Python module that starts running. When TF depends on those packages, the package version needs to, # match the current TF version. Therefore, writing Python code as a script and running it as a script is the most obvious option, especially when the Python program is as simple as a single file. Counterexamples to differentiation under integral sign, revisited, Connecting three parallel LED strips to the same power supply. setup.py find_packages package_dir : package_dir={'': 'src'} root package src --keywords . Python package is nothing but a folder containing Python modules. / setup.py src/ __init__.py foo.py bar.py an appropriate setup script would be from distutils.core import setup setup(name='foobar', version='1.0', package_dir={'foobar': 'src'}, packages=['foobar'], ) Or, you might put modules from your main package right in the distribution root: / setup.py __init__.py foo.py bar.py So, once you test and experiment with your package, follow the instructions below to upload your package to the real PyPI: Go to PyPI and create an account. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Chapter 3: How to package a Python provided a practical overview of how to create, install, and distribute a Python package. example.py is an example of a module within the package that could contain the logic (functions, classes, constants, etc.) And, just as with that option, you can use the empty string key "" in setup.py and the asterisk * in setup.cfg and pyproject.toml to match all top-level packages.. Any files that match these patterns will be excluded from installation, even if they MacOS Windows. When using this option, the Python interpreter will search sys.path for the named module and execute it. Despite a bit of a Despite a bit of a Since pybind11 does not require NumPy when building, a light-weight replacement for NumPys parallel compilation distutils tool is included. Compiling from the command line . What does ** (double star/asterisk) and * (star/asterisk) do for parameters? The setup.py generates the manifest.in with the following line:recursive-include pyil *. } For example, this setup.py provides a $ python setup.py upload command, which creates a universal wheel (and sdist) and uploads your package to PyPi using Twine, without the need for an annoying setup.cfg file. The relationship between the setup.py file and the build tools is similar to CMakeLists.txt to CMake. The main difference between a module and a script is that a script is designed to execute directly, whereas a module is made to be imported. To make a Python package runnable, we need to add a __main__.py file into the top level of the package, and then our mypackage becomes the following: The __main__.py is used to provide a command-line interface for a package. package_data So, once you test and experiment with your package, follow the instructions below to upload your package to the real PyPI: Go to PyPI and create an account.

The maintainer who is the "dependency-maintainer" for Apache Airflow will present the solutions that allowed Airflow to survive breaking one monolithic package into anout 80 smaller ones and continue releasing Airflow for the last 4 years. Python has a similar approach, and many tools serve this purpose, such as setuptools and wheel (see Distributing Python Modules for more details). The command will look for the local setup.py and install the package (mypackage in this example) into the site-packages folder of our Python environment. We had seen how this worked at the beginning of this section when the mylib.py example was imported, the Running from the module was not executed. How do I install a Python package with a .whl file? In Python 3.3 onwards you don't need __init__.py files in your subdirectories for the purpose of imports.

Here we create a basic flask web server; And a module main2.py that imports mylib2.py. 2.0](https://github.com/tensorflow/tensorflow/blob/master/LICENSE). --author ------ Assuming we have a module called mymodule.py with the following content: When we use the Python interpreter to import the mymodule.py module, the print function will show the value of __name__ is mymodule. The way Python structs modules is called Package. The example above shows that we have a package called mypackage, and within mypackage, we have another package, mylibrary, which contains the module that provides the actual functionalities. Also, a file containing Python definitions and statements is called a module. These are: setup.py; readme.md; requirements.txt; __init__.py; License; Almost all projects benefit from these files from one way or another and it can even be said that they are necessary for packaging a Python library. However, when the module is executed as an executable, its __name__ becomes __main__. The cythonize command takes a .py or .pyx file and compiles it into a C/C++ file. --description ------- This post discusses different ways in which those having a C++ background can run and build Python code. It then compiles the C/C++ file into an extension module which is directly importable from Python. Since the module module is part of the mylibrary package, and mylibrary package is part of the mypackage package, the import path needs to include the packages. as a However, the value is not always the same but depends on how the module was executed. # This version string is semver compatible, but incompatible with pip. --version (-V) ----egg Here is what my setup.py looks like: from setuptools import setup, Extension, find_packages module1 = --long_description --- (src) did not work. Because of this, we dont need to designate that our Python code is a library or an executable every Python module is importable and executable. EggsecutableEggsexecutableeggs.eggJava.jar, python *.eggtest().eggPATH, from setuptools import setup setup() You can then install your package in editable mode by running from the same directory: pip install -e . In all cases getting setup.py to build a distribution and work with cx_freeze or platform installers is a lot of difficult work. This is usually frowned upon. --platforms When our project gets more complex, we must organize our code properly. Assuming the code we want to import mylib.py into is called main.py and both modules are in the same folder, the main.py can import the mylib.py module as follows: And then, we can run the main.py module, as the previous example shows. One of the locations should end with python3.7/site-packages . Package structure and distribution. """, # pylint: disable=assignment-from-no-return, The install_headers that comes with setuptools copies all files to, the same directory. --maintainer_email It then compiles the C/C++ file into an extension module which is directly importable from Python. @sinoroc I thought about, but I think it is highly specific. # Copyright 2015 The TensorFlow Authors. To build our basic Python package, we need two components, namely a setup.py file and an src folder containing our package logic. =src) is parsed as {"": "src"}.The "" key has a special meaning in this context, and indicates that all the packages are contained inside the given directory. Mathematica cannot find square roots of some matrices?

Based on your comments to orip's post, I guess this is what happened: You edited __init__.py on windows. Therefore, when we run a module as an executable, it becomes the top-level environment, so its __name__ becomes __main__. ), but nothing worked so far. For example, you can have the {find = {where = ["src"], exclude= ["tests*"]}} directive for tool.setuptools.packages, or {attr = "mymodule.attr"} directive for tool.setuptools.dynamic.version. Learn more about bidirectional Unicode characters. This simplifies the configuration and is more obvious to users who install the package. --cmdclass The following example will describe how to add a CLI entry to our package. Therefore, if our module contains code that should be running only when the module is running in the top-level environment, we should always place the code under the if __name__ == __main__ statement.
