FileNotFoundError：使用 jupyter notebook 时找不到模块

Question

当我尝试使用 jupyter notebook 时，收到以下错误消息：

---------------------------------------------------------------------------
FileNotFoundError                         Traceback (most recent call last)

    374         else:
    375             self._handle = handle

FileNotFoundError: Could not find module 'D:\Anaconda3\lib\site-packages\scipy\.libs\libbanded5x.EHDKC2XVYTQQ5MALRS6XN2CUSS6SRL6P.gfortran-win_amd64.dll' (or one of its dependencies). Try using the full path with constructor syntax.

但我确信该文件就在文件夹中。谁能帮我？

尝试导入 sklearn 时出现同样的问题。我的 scipy 的版本是 1.6.3，我通过将 scipy 降级为 1.6.2 解决了这个问题
