Missing C10_inception_moments.npz

[ShuangjunLiu]

Run script launch_cifar_ema.sh.
Got error:

File "/scratch/liu.shu/codesPool/BigGAN-PyTorch/inception_utils.py", line 279, in prepare_inception_metrics
data_mu = np.load(dataset+'_inception_moments.npz')['mu']
...
fid = open(os_fspath(file), "rb")
FileNotFoundError: [Errno 2] No such file or directory: 'C10_inception_moments.npz'

Seems C10_inception_moments.npz file is missing.
Since cifar is downloaded, I assume this file supposed to be provided by this repo.

老哥，从prepare_data.sh 生成一下就好了

[ShuangjunLiu]

噢，原来这样， I think it is "optional" at first. :)

First, you may optionally prepare a pre-processed HDF5 version of your target dataset for faster I/O

[entrpn]

the hdf5 file creation is optional, but you have to calculate the inception moments.

@entrpn I cannot create the inception moments (.npz file) of my own dataset? any suggestion please?
