How to run multiple rollouts

  • Medium: It contributes to significant difficulty to complete my task, but I can work around it.

Howdy! I’m attempting to run a set of tests that relies on repeated rollouts. Unfortunately I’m experiencing an error on the second run, on ray.init:
ValueError: Attempting to start raylet with 1 GPUs, but CUDA_VISIBLE_DEVICES contains [].

Everything runs correctly the first time, and I do not expect to use a GPU for any of these rollouts.

The problem line of code is specifically:

ray.init(
    num_cpus=1,
    num_gpus=1,
    local_mide=True,
    log_to_driver=True)

Anyone know what is causing this?
