Hi @Jacqueline just letting you know I just released version 1.0.0a2 that includes a temporary fix for this issue. You should be able to pip install vak==1.0.0a2 now to test it. Please do let us know if that fixes things for you if you have a chance.
We plan to replace the device option in the configuration file with accelerator so you can configure this directly and there’s less of an opportunity for this kind of bug to slip in, as discussed here: ENH: Refer to 'accelerator' not 'device' · Issue #691 · vocalpy/vak · GitHub
Thank you again for catching the bug.
