How do we use the pretrained attention aligner?

[vishhvak]

Hi, I find that getting a pretrained predictive aligner (aligner='charsiu/en_w2v2_fc_10ms') to work with librispeech seems straightforward. However, I'm unable to get the attention aligner working - how do I go about initializing the aligner and how do I get the corresponding bert config to go with it? Keeps throwing an error for the same.

What type of error did you get? Did you try our colab tutorial? There are some example scripts for loading the model.
