如何修复 None 返回为 torch 版本？

Question

我在 Windows 11 上使用 Python 3.9.7 [MSC v.1916 64 位 (AMD64)]。 我尝试了火炬 1.10.2 和火炬 1.11.0。在这两种情况下，version.parse 函数都返回 None。

version.parse(importlib_metadata.version("torch"))

。 所以，我收到以下错误：

Answer 1

我在我的环境 site_packages 文件夹中发现了一些 torch-XYZ0-info 文件夹，导致了相同的行为。清理一下就解决了问题。
