[BUG] AttributeError: 'MfccComputer' object has no attribute 'parameters' when aligning dataset.

Debugging checklist

[x] Have you read the troubleshooting page (https://montreal-forced-aligner.readthedocs.io/en/latest/user_guide/troubleshooting.html) and searched the documentation to ensure that your issue is not addressed there? [x] Have you updated to latest MFA version (check https://montreal-forced-aligner.readthedocs.io/en/latest/changelog/changelog_3.0.html)? What is the output of mfa version? [x] Have you tried rerunning the command with the --clean flag?

Describe the issue I want to align some data from Providence Corpus (with .lab files as input). The same error happens both with--clean flag and without. I have tried to validate the corpus with a following command and got the same error: mfa validate archive/Providence_mfa_dataset english_us_arpa english_us_arpa --clean

Both the model and the dictionary are pre-trained and were just downloaded with:

mfa model download acoustic english_us_arpa
mfa model download dictionary english_us_arpa

The output is the following:

Can you try running conda update -c conda-forge kalpy and retry?

Thank you! Now it is fine. There is another strange issue. It got stuck at the Exporting alignment TextGrids to ... stage:
