篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了飞桨CPU版的PaddlePaddle安装总结相关的知识,希望对你有一定的参考价值。

 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

linux python3安装https://blog.csdn.net/wz_coming/article/details/122124026https://blog.csdn.net/wz_coming/article/details/122124026

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(platform.architecture()[0]);print(platform.machine())"

5.  
CPU版的PaddlePaddle

python -m pip install paddlepaddle==2.2.1 -i https://mirror.baidu.com/pypi/simple

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

关于在centos下安装python3.7.0以上版本时报错ModuleNotFoundError: No module named ‘_ctypes‘的解决办法https://blog.csdn.net/qq_36416904/article/details/79316972https://blog.csdn.net/qq_36416904/article/details/79316972

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
Traceback (most recent call last):
