When I run mfa align with --clean flag, it deletes the acoustic and dictionary model, and the aligner does not work. I have to download the acoustic and dictionary models.

I was on the alpha version. I downgraded to the 2.2.17 version and this problem disappeared.

So I can fix this in 3.0, what was the exact command you were running?

[danielanphd]

I did: mfa align --clean . korean_mfa korean_mfa . Almost everything in the Documents/MFA folder got deleted with the --clean and it threw an error of "dictionary not found". So I had to download the dictionary and acoustics again.

I found the problem. If I do mfa align --clean . korean_mfa korean_mfa . Almost everything in the Documents/MFA folder got deleted as I wrote above. However, if I write the directory name in the first ., like mfa align --clean /home/user/wav_txt_directory korean_mfa korean_mfa . then the problem does not happen.
