Failing to train a pretrained model

[piyuch]

I am using the following command to train an existing model:

dora run solver=musicgen/musicgen_base_32khz model/lm/model_scale=medium continue_from=//pretrained/facebook/musicgen-medium conditioner=text2music

But i come across the following error:

omegaconf.errors.MissingMandatoryValue: Missing mandatory value: datasource.evaluate

stacktrace:

I am kind of lost, not sure what do I have to change. Any suggestion will be very helpful.

You should also specify dset=audio/your_dataset param. Follow this link to prepare your dataset.
