ray: General error on game PongNoFrameskip-v4

When I run with Pong-ram-v4 it works but when I run with PongNoFrameskip-v4 as shown below:

python/ray/rllib/train.py --run=IMPALA --config-file=my.yaml Why is the selection of the game cause this kind of error? I am going to try to update my cudnn and see if that fixes it…

My config-file is

pong-impala:
    env: Pong-ram-v4 
#    env: PongNoFrameskip-v4    
    run: IMPALA
    config:
        sample_batch_size: 50
        train_batch_size: 500
        num_workers: 7
