module not found - can't download any acoustic models or dictionaries

[caitlin....@gmail.com]

Can anyone rescue me from a really basic error? I've used MFA before on a mac at my previous institution (not usually a mac user, just was the computer in the lab) but now I'm trying to install it on my laptop at a new role. I've followed the installation instructions here (https://montreal-forced-aligner.readthedocs.io/en/latest/installation.html#general-installation, using mamba) but I'm hitting errors as soon as I try to download any models or dictionaries - example below with the US English acoustic model, but it's happening with the UK one and the dictionaries too.

Can you try updating via `conda update -c conda-forge montreal-forced-aligner kalpy`?  That should get mfa=3.0.4 and kalpy=0.6.4 as the latest versions that should fix the issue.  If not, could you try running `conda install -c conda-forge kaldi=*=cpu*` and see if that fixes it?  Either way, could you let me know which one fixes it for you? I'm working on pinning the CPU version in conda, but it's a trial and error process with each release.

Thanks!

Seems that the second one has worked. I can now download dictionariesand acoustic models. I've downloaded the English UK one. Though I have to admit I'm considering a slight hack which would be using the American one with a custom derhotacized dictionary so that I can then use the TextGrids with FAVE, but that's not a problem at your end!
