1.问题描述

一开始用pycharm，tensorflow2.0，去编写卷积神经网络的代码，是可以正常运行的，过了几天去编译又报错了。

1.1numpy版本报错

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.

We have compiled some common reasons and troubleshooting tips at:

https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

* The Python version is: Python3.7 from "D:Anaconda3envs ensorflowpython.exe"
* The NumPy version is: "1.20.2"

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

Original error was: DLL load failed: 找不到指定的模块。

2.问题分析

pycharm会对库 版本更新，升级新的版本，导致版本不匹配。

3.解决方案

还原到原来的版本

（1）打开anconda prompt命令行

（2）输入activate tensorflow激活tensorflow环境

(base) C:Usersaochunlei>activate tensorflow

（3）先输入pip uninstall numpy卸载

(tensorflow) C:Usersaochunlei>pip uninstall numpy
Found existing installation: numpy 1.20.2
Uninstalling numpy-1.20.2:
Would remove:
d:anaconda3envs ensorflowlibsite-packages umpy-1.20.2.dist-info*
d:anaconda3envs ensorflowlibsite-packages umpy*
d:anaconda3envs ensorflowscriptsf2py-script.py
d:anaconda3envs ensorflowscriptsf2py.exe
Would not remove (might be manually added):
d:anaconda3envs ensorflowlibsite-packages umpy.libslibopenblas.PYQHXLVVQ7VESDPUVUADXEVJOBGHJPAY.gfortran-win_amd64.dll

d:anaconda3envs ensorflowlibsite-packages umpy andom\_bit_generator.pxd
Proceed (y/n)? y
Successfully uninstalled numpy-1.20.2

（4）再输入pip install numpy==1.18.5安装指定低版本的numpy

（5）卸载pip uninstall h5py

(tensorflow) C:Usersaochunlei>pip uninstall h5py
