Can't start training?

[foreversolar]

After following the instructions to download and convert the data, I run the program as

export EXPNAME=baseline_imagenet
for BACKBONE in resnet mamlconvnet mamlresnet
do
  export JOBNAME=${EXPNAME}_${BACKBONE}
  python -m meta_dataset.train \
    --records_root_dir=./converted_data \
    --train_checkpoint_dir=./output/checkpoints/${JOBNAME} \
    --summary_dir=./output/summaries/${JOBNAME} \
    --gin_config=meta_dataset/learn/gin/best/${JOBNAME}.gin \
    --gin_bindings="Trainer.experiment_name='$EXPNAME'"
done

but then the error says

it seems that something wrong with the gin?

in the gin->resource_reader.py

def _parse_config_path(config_path: str) -> str:
  head, filename = os.path.split(config_path)
  pkg = head.replace('/', '.')
  spec = importlib.util.find_spec(pkg)                                  #  this line return a spec with None origin ! !
  if spec is None:
    raise ValueError('Package not found', pkg)
  file_sys_path = spec.origin
  # file_sys_path often ends with __init__.py.
  path = os.path.join(os.path.dirname(file_sys_path), filename)    # input None here cause the error 
  return path
