Hello, the platform may not have data in MINERL_DATA_ROOT at the submit time. I have the following error:

Code in train.py (from baseline actually):

MINERL_GYM_ENV = os.getenv('MINERL_GYM_ENV', 'MineRLObtainDiamond-v0')
MINERL_DATA_ROOT = os.getenv('MINERL_DATA_ROOT', 'data/')
data = minerl.data.make(MINERL_GYM_ENV, data_dir=MINERL_DATA_ROOT)

I understand that training timeout is 15 minutes, but reading data at the beginning of my train.py and it take less than a minute locally.
