failed to load BF in 1.0-segment-song-from-wavs.ipynb

[robinmeier]

when running 1.0-segment-song-from-wavs.ipynb i get errors during the last step:

100% 135/135 [00:00<00:00, 3939.66it/s]
failed to load BF
failed to load BF
failed to load BF
...

all the rest seems to be working. not sure what i'm missing. the wav count and folder structure in */data/ is correct.

fwiw, 13.0-koumura-bengalese-finch-custom-parsing.ipynb in the avgn_paper repo is working for me and generates the json files.

Hi @robinmeier

Sorry for the slow reply. Could you try removing the exception that prints "failed to load BF" and see where the error is occuring in the code? To play with the code you should try installing with python setup.py develop instead of python setup.py install.

hi @timsainb
thanks for getting back to me. here's the error message with the exception removed:

Hi Robin,

That error message is saying that the directory /BF/ does not exist, so whatever path is supposed to be pointed at the wav files is pointed somewhere else.

Are you using windows? It's possible that this code doesn't work with windows file structure. You'd need change the file path to point at the actual location of the WAV files to get this to work then.

[robinmeier]

i'm not sure BF is supposed to be a directory. it's declared here:
dsets = [(input_loc+'Bird*/Wave/*.wav', 'BF')]
am running on osx and changed the path to the wav files of the dataset here:
input_loc = '/Volumes/1TSSD/bird_datasets/3470165/'

[timsainb]

Yes, I'm not 100% sure what the problem here is without having access to your filesystem and the code. If the data is correctly downloaded to '/Volumes/1TSSD/bird_datasets/3470165/Bird*/Wave/*.wav' then it should be seeing that data. It might be worth trying the other repository which has examples with the same dataset if you continue to have trouble finding the correct files:

Hi robinmeier,

Did you solve this problem? I have the same issue. Could you please teach me how did you solve that?

Thanks!
