Calculate FID with CelebA or LSUN datasets

[parkjjoe]

I want to calculate the FID for CelebA or LSUN datasets by writing the code: fidelity --isc --fid --input1 ./logs/cifar10_generated --input2 cifar10-train (Code example is CIFAR-10).

But I don't know what to write for --input2. fidelity does not seem to provide CelebA or LSUN datasets. Then, after saving all CelebA or LSUN train dataset images, should I extract only 50,000 images and save them in another directory?

Or is there an easier way?
