How to find PSNR from two images with different size in python

I have 2 images, one original and other is reconstructed from the original via some processing. I want to find the PSNR for the reconstructed image The original has a size of (180, 180) but the reconstructed image has size of (71,81) Since the sizes do not match, it will give an error while calculating it. Is there a way to resize the reconstructed one to (180,180). I am also worried that there might also be an alignment issue so it may give wrong PSNR. What can be done to do calculate the PSNR
