如何解决导入TensorFlow GPU时的charset_normalizer循环导入错误

问题描述 #

执行代码：

import tensorflow as tf

触发如下错误：

AttributeError: partially initialized module 'charset_normalizer' has no attribute 'md__mypyc' (most likely due to a circular import)

完整报错回溯：

AttributeError                            Traceback (most recent call last)

已尝试安装requests、chardet、openpyxl，问题仍未解决。

解决方案 #

该错误由charset_normalizer模块损坏或版本冲突引发，按以下步骤修复：

• 卸载并重装charset_normalizer
  激活Anaconda环境后执行命令：

  pip uninstall -y charset_normalizer
  pip install charset_normalizer
  

• 指定兼容版本安装
  若重装无效，安装稳定兼容版本：

  pip install charset_normalizer==3.3.2
  

• 检查环境依赖完整性
  执行命令排查其他依赖问题：

  pip check
  

  根据提示修复对应依赖包。

• 重置TensorFlow GPU
  若以上方法均无效，卸载并重新安装TensorFlow GPU：

  pip uninstall -y tensorflow-gpu
  pip install tensorflow-gpu==2.15.0
  

  替换2.15.0为你需要的目标版本号。
