python setup.py：安裝tensorflow還是tensorflow-gpu？

Question

我正在設計一個需要張量tensorflow的新項目。 由於TensorFlow具有多個安裝（ tensorflow和tensorflow-gpu ），我如何在install_requires部分中添加兩個都可以呢？

Answer 1

所以這是我的解決方法：

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)
