Error importing tensorflow.  Unless you are using bazel, you should
not try to import tensorflow from its source directory; please exit
the tensorflow source tree, and relaunch your python interpreter from
there.

现有环境说明 #

• 系统sys32文件夹中存在MSVCP.dll文件
• 当前安装CPU版本TensorFlow，设备搭载Nvidia MX250显卡

修复步骤 #

• 校验工作路径：不要在TensorFlow源码目录、site-packages下的tensorflow目录内运行代码，切换到自定义的独立项目目录后重试。
• 替换Python版本：当前使用的是32位Python3.7，新版本TensorFlow已停止对32位Python的支持，建议卸载32位Python，安装64位Python3.8~3.10版本，兼容性更好。
• 重装适配版本TensorFlow：如果继续使用现有32位Python3.7环境，先卸载所有残留TensorFlow包：

  pip uninstall tensorflow tensorflow-cpu -y
  

  再安装适配32位Python3.7的低版本CPU TensorFlow：

  pip install tensorflow-cpu==2.1.0
  

• （可选）安装GPU版本：MX250显卡支持TensorFlow GPU加速，配置对应版本的CUDA、cuDNN环境后，安装对应版本的tensorflow-gpu包即可获得更高的运行效率。
