The calculation of fid is too slow. #83

Thanks for sharing.

The calculation of fid is too slow. The calculation for linalg.sqrtm(sigma1.dot(sigma2), disp=False) takes several minutes. How to speed it?

How many images do you use to compute FID? This line becomes slower with the number of images you use, but unless you use a really large number of images, this should not be an issue.

Should I divide the FID score, I have calculated, by the number of images to get the average value? 1000 images and get scores of 70.
