I run:
python train.py --config configs/maml/bandit/bandit-k5-n10.yaml --output-folder bandit/bandit-k5-n10/ --seed 1 --num-workers 8
but fail:
Process SamplerWorker-1:
Process SamplerWorker-2:
Process SamplerWorker-3:

what's wrong with this?
I am not able to reproduce this error. The script is running on my end with the command you give, with the latest version of the code. Did you change anything in the code, or are you running it straight from master? This error should not happen, because infos is not a list but a dict
