Hi @herveyrobot and @nbqu , #51

          Hi @herveyrobot and @nbqu ,

The example.py code was written with the assumption that it would be run on a mac, sorry about that! As the error message notes:

[d != torch.device("cpu") and d >= 0 for d in devices]
TypeError: 'NoneType' object is not iterable
[engine.py: 1861]

the parameter devices passed to the TwoPhaseRGBBaseExperimentConfig.stagewise_task_sampler_args function is None by default which is fine when you're not using Linux but causes issues otherwise. Can you try changing:

task_sampler_params = TwoPhaseRGBBaseExperimentConfig.stagewise_task_sampler_args(
    stage="train", process_ind=0, total_processes=1,
)

to

task_sampler_params = TwoPhaseRGBBaseExperimentConfig.stagewise_task_sampler_args(
    stage="train", process_ind=0, total_processes=1, devices=[0]
)

and trying again?

It can't work for me. The errors that occurred are as follows：
