pip3在尝试安装tenstorflow时抛出一个错误

Question

我一直在安装Python 3的一系列基本包（Numpy等）与pip 3和一切都很好。然后我尝试安装tensorflow图形处理器，我得到了

user@computer:~$ pip3 install --upgrade tensorflow-gpu
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 33, in vendored
    __import__(vendored_name, globals(), locals(), level=0)
ImportError: No module named 'pip._vendor.pkg_resources'

During handling of the above exception, another exception occurred:

AttributeError: '_NamespacePath' object has no attribute 'sort'

我清除了python3pip并重新安装了它，这没有帮助。

编辑：我得到同样的错误，如果我只是运行pip3在终端。

EDIT2：好的，我只是想说清楚，我不能用pip3来完成任何任务。运行pip3安装setuptools会出现相同的错误。我也没有在假设的重复问题中找到任何解决方案。

Answer 1

AttributeError: '_NamespacePath' object has no attribute 'sort'

这看起来好像您缺少了另一个模块，您可以尝试

pip3 install setuptools
