问题描述

在使用 python3.8 安装 paddle 以后，测试导入 paddle 报错。

创建环境并安装
source activate paddle38
pip install paddlepaddle-gpu -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install paddlehub -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install paddleocr -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install paddleclas -i https://pypi.tuna.tsinghua.edu.cn/simple
python
>>> import paddle

问题分析

查看很多资料，发现最大的可能性是安装依赖包时对应版本错误，显卡驱动不支持 cuda10.2 或者没有安装正确的驱动，我这里安装的驱动是 cuda11.7 和默认的驱动不匹配，所以需要重新安装。

解决方案

使用的 conda 安装 python3.8，通过指定版本和国内镜像进行安装

source activate paddle38
conda install paddlepaddle-gpu==2.4.2 cudatoolkit=11.7 -c https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/ -c conda-forge
# 或者使用 pip 安装
python -m pip install paddlepaddle-gpu==2.4.2.post117 -f https://www.paddlepaddle.org.cn/whl/linux/mkl/avx/stable.html
