python setup.py：安装tensorflow还是tensorflow-gpu？

Question

我正在设计一个需要tensorflow的新项目。由于TensorFlow具有多个安装（tensorflow和tensorflow-gpu），我该如何在我的install_requires部分中添加以下任意一项？

Answer 1

这就是我的解决方法：

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)
