mfa align ZeroDivisionError: division by zero

[caitlin....@gmail.com]

Hi all,

I'm having problems with the newly downloaded version 2, validate works fine, but align is giving an ZeroDivisionError: division by zero (full traceback below). I'm doing this with the librispeech data from the MFA documentation website, so it's not something to do with my files, so I think must be an issue with my installation. There's also a rather concerning warning in the middle (highlighted in red). I can't work out what the error would be referring to, anyone encountered this? Answers or troubleshooting ideas welcome.

I have the same warning. When I go to validate my files, it says that everything is fine with my files; it just won't align.

My error is different than yours because the first pass alignment doesn't return an error in verbose, but when it moves on to the second step of "generate alignment' it returns the warning that you have above.

At the end of the process, the INFO says "Exporting textgrids to (path)", "Finished exporting textgrids to (path)", and "Done!" When I go to that particular folder, nothing is there and it is completely empty.

I don't know if you fixed this by now but I've just installed on a different user profile on my computer and it's all working...I think it was because there's a space in my home directory (C:\Users\Caitlin Halfacre).
