Hello， thanks for your wonderful work. I run in colab and I have met an error recently. but I don't know how to fix it.
Here is the whole message:

create inception graph.. ok
calculte FID stats..

I am having this same issue. Worked file on my Windows10 machine but when trying to use it in linux I got this same error

[Erdem Ünlü]

I've fixed the issue by deleting "FID_Inception_Net" from create_inception_graph, _get_inception_layer, and get_activations. The problem is probably due to the Colab's different path.

Thanks a lot!
For people noob like me. Just use google's tf upgrade tool. Then whereever "FID_Inception_Net" is there. Change it to "FID_Inception_Net". If "FID_Inception_Net/something" then "something".
