num_samples should be a positive integer value, but got num_samples=0 about open-unmix-pytorch

@loxosceles sorry for the long delay, I will look into it this week

@faroit
Is there any answer?
i ran into the same error with musdb stem dataset.

[faroit]

@eranmenachem are you using the FixedSourcesTrackFolderDataset as well?

[eranmenachem]

@faroit
No, i am using the following command (just to check that training of the musdb stem data set runs well, before i'll run training on combined data set of musdb and my own).
python train.py --root path/to/musdb18 --target vocals

where the <path/to/musdb18> is a path to a directory containings the train data set of musdb of stem files.

@eranmenachem does training work with the 7s Previews? (Just omit the --root option). If that is the case, please compare your folder structure of the 7s Preview to your downloaded dataset

[eranmenachem]

it worked with the 7s Previews and it appeared to me that my downloaded dataset structure wasn't similar to the 7s Previews. I changed it accordingly and it works now.
Thank you very much!

@eranmenachem 👍

@loxosceles regarding your issue, can you check if the error happens with train and validation or with just one of it?

Also do you see any warnings raised by this part of the code?

open-unmix-pytorch/data.py

Lines 519 to 521 in 93077eb

	if not all(sp.exists() for sp in source_paths):
	print("exclude track ", track_path)
	continue

@eranmenachem can this be closed?

[eranmenachem]

yes, thank you!
