The progress bar doesn't increase at all

[seolhokim]

after pip install -r requirements.txt,

I ran
python train.py --config configs/maml/halfcheetah-vel.yaml --output-folder maml-halfcheetah-vel --seed 1 --num-workers 8

but progress doesn't increase after �a day.
0%| | 0/500 [00:00<?, ?it/s]

I found that is waiting valid_futures.

pytorch-maml-rl/maml_rl/metalearners/maml_trpo.py

Line 96 in 21d4ba1

valid_episodes = await valid_futures

but how can i fix it?

It is too difficult for me to find the exact line where the error occurs because even one worker is stuck at another point.
