Installation issues

I created a new python virtual environment and installed everything in the requirements.txt. Now I'm getting this issue. Any ideas or pointers? Can't quite find the solution sadly.

Traceback (most recent call last):

Hi, as mentioned in the link https://www.jianshu.com/p/f5d421458746?v=1705760805683 in this post #19 (comment), you can use pip install pytorch_lightning==1.6.5
