Unable to run Fastpitch_finetuning.ipynb version main from scratch
State: closed | Pull request: no

Hi, I'm trying to run FastPitch_finetuning.ipynb from scratch, but I'm getting this error:

```
# TODO(oktai15): remove +model.text_tokenizer.add_blank_at=true when we update FastPitch checkpoint
!(python fastpitch_finetune.py --config-name=fastpitch_align_v1.05.yaml \

And the error:
```
