I ran this command :

mfa train --phone-set PINYIN /storage/mfa_TAT ./syl2phone/syl2phone.txt ../MFA/mfa_data/tat_acoustic_model.zip ../MFA/mfa_data/tat_aligned

and resulted in this error when training lda:

FileNotFoundError: [Errno 2] No such file or directory: '/home/briannnyee/Documents/MFA/mfa_TAT_train_acoustic_model/lda/2.syl2phone.0.acc'
