RuntimeError: Can't call numpy() on Variable that requires grad. Use var.detach().numpy() instead

When I call python Edge_removal.py in the MISA directory after following the first steps, I obtain the error below. I am using Python3.8, and numpy version 1.22.3. Are they the right versions?

python Edge_removal.py
