🐛 Bug

A recent commit: 2513524 added two new fine-tuned Wav2Vec2 checkpoints, however it seems like there is a problem with the saved config as one cannot load those checkpoints. E.g. the following code cannot be run:

import fairseq
model, _, _ = fairseq.checkpoint_utils.load_model_ensemble_and_task([checkpoint_path], arg_overrides={"data": "path/to/dict"})

To Reproduce

The following colab reproduces the error (one just has to run all cells):
