Omegaconf MissingMandatoryValue error trying to train a base model Wav2Vec2.0

[gandroz]

🐛 Bug

To Reproduce

Steps to reproduce the behavior (always include the command you ran):

1. After building a manifest from LibriSpeech, I tried training a base model Wav2Vec2.0
2. Use the configuration wav2vec/config/wav2vec2_base_librispeech.yml
3. Add task.data directly in the config file instead of passing the argument to the CLI
4. Run command HYDRA_FULL_ERROR=1 fairseq-hydra-train --config-dir ~/src/fairseq_dev --config-name wav2vec2_base_config

says it doesnt have a model field?
actually i am not sure if hydra supports "yml" extensions, can you try yaml? if that doesnt work plz share your config

@alexeib simple as that ! it was due to the yml extension.. changed to yaml and it works fine. Thanks
