IsADirectoryError when training HiFi-GAN

[Dimitar971]

When I try to train the HiFi-GAN in the Training colab, I get this error

This error only started appearing today, it has never happened before. I tried deleting the HiFi-Gan folder, but this did not help. Why would this error appear now? I'll be thankful for a response.
