python - 无法在 Ubuntu 中使用 setup.py 中的 Github Actions 安装 Tensorflow 2.2.0rc0

Question

当我尝试从 setup.py 安装 tensorflow>=2.2.0rc0 从 Github Actions Workflow 运行 python setup.py install , 输出发送给我:

Searching for tensorflow>=2.2.0rc0
Reading https://pypi.org/simple/tensorflow/
No local packages or working download links found for tensorflow>=2.2.0rc0
error: Could not find suitable distribution for Requirement.parse('tensorflow>=2.2.0rc0')
##[error]Process completed with exit code 1.

这是我的 Github Action 工作流程:

name: Test Deblurrer

on: 
  push:
    branches:
    - master
    - development 
  pull_request:
    branches:
    - master
    - development

jobs:
  build:

    runs-on: ubuntu-latest
    strategy:
      max-parallel: 4
      matrix:
        python-version: [3.7]

    steps:
    - uses: actions/checkout@v1
    - name: Setup Python ${{ matrix.python-version }}
      uses: actions/setup-python@v1
      with:
        python-version: ${{ matrix.python-version }}

    - name: Install dependencies
      run: |
        sudo apt-get install libpq-dev python-dev
        python -m pip install --upgrade pip
        python setup.py install
        pip install pytest

    - name: Test with pytest
      run: |
        PYTHONPATH=${PYTHONPATH}:/home/runner/work/deep-deblurring/deep-deblurring/backend:$(pwd)
        pytest

接下来是我的setup.py:

#!/usr/bin/python
# coding=utf-8

"""Setup and install the package and all the dependencies."""

from setuptools import setup, find_packages

with open('requirements.txt') as pro:
    INSTALL_REQUIRES = pro.read().split('\n')

setup(
    author='Whitman Bohorquez, Mo Rebaie',
    author_email='whitman-2@hotmail.com',
    name='deblurrer',
    license='MIT',
    description='Image Deblurring using Deep Learning Architecture',
    version='1.0.0',
    url='',
    packages=find_packages(),
    include_package_data=True,
    python_requires='>=3.6',
    install_requires=INSTALL_REQUIRES,
    classifiers=[
        'Development Status :: Alpha',
        'Programming Language :: Python',
        'Programming Language :: Python :: 3.6',
        'Intended Audience :: Developers',
    ],
)

最后，我的 requirements.txt:

grpcio == 1.27.2
kaggle
numpy
tensorflow >= 2.2.0rc0
pandas

我不明白为什么在 Github Actions 上会发生这种情况，但是在 Windows 10 上本地安装时它会按预期工作。

提前致谢!

PD:当我直接在 Github Action Workflow 上执行 pip install tensorflow==2.2.0rc0 时，而不是在 python setup.py install 中，它也能正常工作。所以这不适用于 setup.py，并且仅适用于 Ubuntu

问题出在过时的 setuptools 版本上。从 2.0 开始，tensorflow 仅在 Linux 上提供带有 manylinux2010 标签的轮子。 setuptools 添加了对 manylinux2010 的支持 in 42.0.0 ，因此升级 setuptools 将解决问题:

$ pip install setuptools>=42.0.0
