When using axolotl in HPC environments, commonly without access to the internet, HF_DATASETS_OFFLINE enviroment variable need to be set. This causes data loading, even for a JSON file, to throw an uncatched error and impeding the training run to begin.
This addition catches
ConnectionError
and continues treating it as if it was aFileNotFoundError
, checking for local files next.You can test the difference just by adding
HF_DATASETS_OFFLINE=1
to the training command. The run must use a local JSON file.
