Greetings,
I am receiving the following error.

Hi, @derrickjnet thanks for reporting. For the record, I can replicate this with an MP3 audio file. Will look into it!

Awesome, please keep me updated. We're using prodigy solely for audio.

Hi @derrickjnet , a bugfix is already underway, but it will be part of the next release.

In the meantime, it is possible for you to patch it yourself so you can keep working (it's just a one-line change). We ship the uncompiled source of the recipes and they're accessible in your machine.

First, you need to know the location where prodigy was installed. You can do so by running:

prodigy stats

This will reveal the Location of the prodigy files. If you're on Linux, it's usually in the .local directory of your home folder (specifically under site-packages). Then head over path/to/prodigy/recipes/:

cd path/to/.local/lib/python3.8/site-packages/prodigy/recipes

and open audio.py.

There, you can edit the get_stream call inside the transcribe function. You just need to add rehash=True

- stream = get_stream(source, loader=loader, dedup=True, is_binary=False)
+ stream = get_stream(source, loader=loader, rehash=True, dedup=True, is_binary=False)

In my Prodigy version (1.11.4), this is in line 108. Remember to do it within the transcribe() function.
Lastly, save the file and try rerunning your command. Hope it helps!
