@snow-orld 可以尝试一下使用python3.8.0

源自github用户snow-orld:
我在另一台Win10笔记本上安装后不会报错，导入成功。用的也是Python3.8.4

源自github用户gfwm2013:
@snow-orld 可能这台windows机器的环境存在着一些问题。

源自github用户snow-orld:
已解决。
C:\Program Files\Python38\lib\site-packages\paddle\fluid文件夹下的core_avx.pyd加载出错，因为:

DLL load failed: The specified module could not be found When a Python extension module is compiled it may depend on some additional libraries called DLLs, or Dynamic Link Libraries. If these DLLs can't be found when trying to load the Python extension module then the module won't be able to be imported and that is what this error is telling you.

出问题的台式机只装了Microsoft Visual C++ 2015 Redistributable，运行OK的笔记本上是Microsoft Visual C++ 2017 Redistributable。安装Microsoft Visual C++ 2017 Redistributable后，问题解决。

Microsoft Visual C++ 2017 Redistributable安装方法：https://social.msdn.microsoft.com/Forums/vstudio/en-US/e653a57a-bc32-4134-87bf-df33058f0531/download-microsoft-visual-c-2017-redistributable
