TypeError: expected str, bytes or os.PathLike object, not list about maia-chess

Your providing a list in the yaml, it's expecting a string

The yaml for maia_config is in a list, so I don't get it.

[reidmcy]

Please check again, here this is the relevant line. I'm not sure which config you are using there

Ah, thanks. It works now. However, when it goes through the training games, it comes back as 0 chunks total. I don't know why that happening when there's the data there.

It's not looking for the the directory to the files, did you read the comment in the yaml?

I did read the comments of the YAML and followed it to the tea. Still detecting zero chunks.

Then you are putting in the wrong path, glob.glob() will produce [] when nothing is found

I've replicated the same path as the final config in the configuration file, and it's still giving me no chunks.

This is literally my config file:

You're on Windows, that's almost certainly not a valid path on your OS. Where are your datafiles? The paths should point to them. The code we provide is intended for replication, it is not meant to be a turnkey run code and it just works, it's intended for other researches to replicate our work.

Ah, okay. That makes sense. I just assumed the training was similar to that of when you train Leela Chess Zero using supervised learning, which I have done before.

As for data files, I'm not sure what you mean by that.

[reidmcy]

Did you do steps 1 and 2 of the instructions? That's for generating the training data, those are converted to the training/validation data files in step 2.

After fiddling about for hours on Windows, trying to get it to work, I got train_maia.py working! I'm going to start training Maia to be rated at around 2500.
