KeyError: 'HF_HOME'

[fallcat]

Hi!
I was trying to run the example in README, but it says KeyError: 'HF_HOME'
This is the script I used: python -m src.pl_train -c t03b.json+rte.json -k save_model=False exp_name=first_exp
I can't find anywhere in the code that sets the value of this environment variable.

Mark experiment first_exp as claimed
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
Using bfloat16 Automatic Mixed Precision (AMP)

I have encountered the same problems! @dptam @muqeeth @jmohta

Same error in python -m src.pl_train -c t011b.json+rte.json -k save_model=False exp_name=first_exp

Hi,
HF_HOME is an environment variable that can be set running the following command in terminal:
export HF_HOME=/<directory_path_for_huggingface_cache>/

where <directory_path_for_huggingface_cache> can be any directory that can store huggingface cache.

This link https://stackoverflow.com/questions/63312859/how-to-change-huggingface-transformers-default-cache-directory is to set transformers cache directory but the idea is the same for huggingface cache too.
I hope it helps.
