The following modules need to be imported in the program:
from skimage.metrics import peak_signal_noise_ratio as compare_psnr
Error:
ModuleNotFoundError: No module named 'skimage.metrics'

You can see that skimage has been installed, the version is 0.14.2.
From the article ImportError: cannot import name 'metrics' from 'skimage', I learned that the version of skimage I installed is too low, resulting in no metrics:
Try to install latest version of skimage because that version does not have that module in it so use below command to upgrade it!
So type:
pip install scikit-image --upgrade
Just update the skimage version. The updated version is 0.18.3, and the module can be imported normally.
