Python3.9 Anaconda环境Jupyter Lab启动报错：无法导入TypeVarTuple

环境信息 #

• Anaconda自定义环境：gpu_env
• Python版本：3.9（为适配tensorflow-2.5.3、tensorflow-gpu-2.10.0、tensorflow-io-0.18.0及Nvidia GTX-1060的CUDA支持）
• 系统：Windows 10 Pro 22H2 x64
• 此前正常流程：激活环境后执行jupyter lab即可启动Jupyter Lab

问题触发流程 #

执行笔记本代码data = data.map(preprocess)出错，重启系统后，环境激活正常，但运行jupyter lab时抛出以下错误：

解决步骤 #

1. 确保已激活gpu_env环境：

   conda activate gpu_env
   

2. 升级typing_extensions到支持TypeVarTuple的版本：

   pip install --upgrade typing_extensions
   

3. 若直接升级后仍有兼容问题（比如和Python3.9冲突），可指定适配版本：

   pip install typing_extensions==4.5.0
   

4. 重新启动Jupyter Lab：

   jupyter lab
