Finetuning hifigan
**Hydra conf path not found**

I have been trying to run fastpitch_finetune.ipynb and from inside the nemo docker container. While the code ran bug free till inference of fastpitch model, when I am trying to run the steps given to run hifigan_finetune.py it throws an error related to config path

Primary config directory not found.
Check that the config directory '/TTS/conf/hifigan' exists and readable

Set the environment variable HYDRA_FULL_ERROR=1 for a complete stack trace.
Or 
path not present in hydra_search_config.


I have been running it on a vm instance with a t4 gpu.
Please reach out if you know why this is happening and how to resolve this.
I have checked hydra directory for this error and tried a few solutions from there the problem is persistent.
