online2-wav-nnet3-latgen-faster，error：Input feature dimension mismatch: got 40 but network expects 43 #3511

seems to me that you train a model with 43 dim features (I think the aishell's mandarin speech contain extra pitch features), but you are using 40 dim mfcc as input

So how should I modify my test input?

weiwchu commented 5 years ago

ah, it also might because of some issues in iVector

Cao you show the content of you online.conf here?

weiwchu commented 5 years ago

I think I met something similar like you, if there is a silence weight factor in the online.conf, I think you might have set it to 0, you can set it to a very small value like 0.00001.

I suspect the issue is that when you called prepare_online_decoding.sh you forgot to add the flags that relate to pitch features. You have to specify the pitch config somehow. Look at the script's usage message or the script itself.
