python setup.py: install either tensorflow or tensorflow-gpu

Question

我正在设计一个需要tensorflow的新项目。由于 TensorFlow 有多个安装(tensorflow 和 tensorflow-gpu (，我如何在我的install_requires部分添加任何一个都可以？

Answer 1

所以我是这样解决的：

from pkg_resources import DistributionNotFound, get_distribution
from setuptools import setup, find_packages    
def get_dist(pkgname):
    try:
        return get_distribution(pkgname)
    except DistributionNotFound:
        return None
install_deps = ['numpy', 'tensorflow']
if get_dist('tensorflow') is None and get_dist('tensorflow-gpu') is not None:
    install_deps.remove('tensorflow')
setup(..., install_requires=install_deps)
