[FIXED] FailedPreconditionError: runs is not a directory

Issue

I made my own GAN with custom dataset that I collected, I wanted to use Tensorboard, It gives me an error.I asked ChatGPT,Bard and BingAI but they couldn't fix the error.

from torch.utils.tensorboard import SummaryWriter

writer_fake = SummaryWriter()
writer_real = SummaryWriter()

I get this error, it creates a new folder named "run", but then raises the error

FailedPreconditionError: runs is not a directory

I searched a lot but couldn't find anything.

Solution

II just had a similar problem and was able to solve it. In my case the problem was that there were russian letters in the path of the .ipynb file (windows username is written in russian). As soon as I moved the file to a different path with only latin letters, the problem was solved.
