paddlepaddle cpu安装问题总结

 1. 可以使用以下命令查看本机的操作系统和位数信息：

uname -m && cat /etc/*release

2. python版本查看，使用以下命令确认是 3.6/3.7/3.8/3.9

python --version

3. 需要确认pip的版本是否满足要求，要求pip版本为20.2.2或更高版本

python -m ensurepip 
python -m pip --version

4. 需要确认Python和pip是64bit，并且处理器架构是x86_64（或称作x64、Intel 64、AMD64）架构，目前PaddlePaddle不支持arm64架构。下面的第一行输出的是”64bit”，第二行输出的是”x86_64”、”x64”或”AMD64”即可：

python -c "import platform;print(()[0]);print(())"

5. CPU版的PaddlePaddle

python -m pip install paddlepaddle==2.2.1 -i /pypi/simple

安装中出现ModuleNotFoundError: No module named ‘_ctypes‘，解决参考博客

6. 安装成功，输入import paddle，显示以下错误

Error: Can not import avx core while this file exists: /usr/local/python3/lib/python3.7/site-packages/paddle/fluid/core_avx.so
