Windows10下仅CPU版TensorFlow安装后导入报错求助

我之前在Windows环境下折腾TensorFlow时也碰到过一模一样的问题，折腾了好一阵才摸清楚解决思路，给你几个经过验证的修复步骤：

1. 匹配TensorFlow与Python版本 #

你当前用的是Python 3.6.5，而高版本的TensorFlow（比如2.6及以上）已经不再支持Python 3.6了，这很可能是核心原因。先卸载现有TensorFlow，再安装适配的版本：

• 卸载命令：

  pip uninstall tensorflow -y
  

• 安装适配Python3.6的CPU版TensorFlow（推荐2.5.0，是最后支持Python3.6的2.x版本；如果项目需要1.x，选1.15.5）：

  pip install tensorflow==2.5.0 --no-cache-dir
  

2. 安装必备的VC++运行库 #

TensorFlow依赖微软的Visual C++ Redistributable for Visual Studio 2015-2019（x64版本），缺失这个库会直接导致DLL加载失败。下载对应64位版本安装后，务必重启电脑再测试导入。

3. 确认PyCharm虚拟环境配置 #

检查PyCharm是否正确使用了你创建的venv：

• 打开File > Settings > Project: connect4-alpha-zero > Python Interpreter
• 确认解释器路径指向你的venv目录下的python.exe（比如C:\Users\Wok\PycharmProjects\connect4-alpha-zero\venv\Scripts\python.exe），且是64位版本

4. 清理pip缓存并重新安装 #

如果安装过程中缓存文件损坏，也会导致模块缺失：

• 清理pip缓存：

  pip cache purge
  

• 重新安装指定版本的TensorFlow（加上--no-cache-dir避免使用缓存）：

  pip install tensorflow==2.5.0 --no-cache-dir
  

5. 检查系统PATH环境变量 #

确保以下路径在系统PATH中，且venv的路径优先级高于系统Python：

• 你的venv的Scripts目录：C:\Users\Wok\PycharmProjects\connect4-alpha-zero\venv\Scripts
• Python3.6的安装目录：C:\Users\Wok\AppData\Local\Programs\Python\Python36
