[BUG] TypeError: __init__() missing 1 required positional argument: 'words_symbols'

[jeffmielke]

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 A clear and concise description of what the bug is.

I updated to 3.1.3 to see how issue #824 was addressed and now I get an error message when trying to align the same test dataset that aligned successfully under 3.1.1: TypeError: init() missing 1 required positional argument: 'words_symbols'

For Reproducing your issue Please fill out the following:

1. Corpus structure
   • What language is the corpus in? English
   • How many files/speakers? 8/8
   • Are you using lab files or TextGrid files for input? textgrid
2. Dictionary
   • Are you using a dictionary from MFA? If so, which one?
   • If it's a custom dictionary, what is the phoneset? arpabet
3. Acoustic model
   • If you're using an acoustic model, is it one download through MFA? If so, which one? english_us_arpa
   • If it's a model you've trained, what data was it trained on?

Log file Please attach the log file for the run that encountered an error (by default these will be stored in ~/Documents/MFA).

Should be fixed by https://github.com/conda-forge/montreal-forced-aligner-feedstock/pull/84, if you can run conda update -c conda-forge montreal-forced-aligner it should pick up the update to kalpy as well.

[jeffmielke]

Thanks. This worked for me.

I am having the same error still although I am using .txt files for my transcription files. I only seem to have this version on 3.2 but not on 2.2.17.

Hi there, I was facing the same error here, but I could fix it after checking the commit cited earlier in this thread. In my case the kalpy lib was on version 0.6.3, so I run: conda update -c conda-forge kalpy And so it was upgraded to 0.6.5... after that, all commands are working again.
