pytorch一直Collecting package metadata (repodata.json):

这可能是由于网络连接问题或PyPI服务器出现问题导致的。您可以尝试通过以下方法解决此问题：

1. 检查您的网络连接是否正常，尝试使用其他网络连接。

2. 清除您的pip缓存并尝试重新安装包。可以使用以下命令清除缓存：

   pip cache purge

3. 指定其他的PyPI源，例如使用清华大学的PyPI镜像源：

   pip install -i https://pypi.tuna.tsinghua.edu.cn/simple some-package

希望这些方法可以帮助您解决问题。
