urllib.error.HTTPError: HTTP Error 404: Not Found

I found that when calculating custom dataset, using UPPERCASE named custom_name such as "dragan_Rs", it will be ERROR. And i change it to "dragan_rs", its OK. I don't know why.

The complete error as follows:
Traceback (most recent call last):
  File "/home/user/duzongwei/Projects/FSGAN/metrics/fid.py", line 46, in <module>

Hi,

Thank you for pointing it out. This is because when the FID stats are loaded, the library checks for the lowercase version of the string. I will address this in the next revision!
