问题描述

下载 Tensorflow1.12 版本，之后在PyCharm中报错：

ImportError: 

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

解决办法

1. 可能是numpy版本过低造成的，因此将numpy更新到最新版本，即可解决！

• 查看numpy的当前版本

conda list numpy
或
pip show numpy

• 更新numpy的版本

pip uninstall numpy

pip install --upgrade numpy
#或者
pip  install numpy -i https://pypi.tuna.tsinghua.edu.cn/simple

也可以这样：

pip install --upgrade numpy
或
pip  install -i https://pypi.tuna.tsinghua.edu.cn/simple --upgrade numpy

或者：

pip install --user --upgrade numpy  # 提升权限

2. 可能是numpy版本过高的问题（我之前的numpy版本是1.19，会报这个错，改成了1.14，就不报错了）：

pip install numpy==1.14.0

或者：

pip install --upgrade --force-reinstall numpy==1.14.5  # 重新安装合适的numpy版本

如果提示权限不够，‘[WinError 5]拒绝访问’，则需赋予管理员权限，用下面语句:

pip install --user --upgrade --force-reinstall numpy==1.14.5

加油!
