@frankaging can you please check.

[AkashGhosh]

Hi @frankaging I tried the demo code as well and it was giving same error .

[frankaging]

@AkashGhosh Hey, do you have multiple GPUs in your env? Could you try a single GPU setting by adding CUDA_VISIBLE_DEVICES=0 before your command (e.g., notebook init command, or script running command)? Current library is not integrated well with DDP yet.

(minor: i removed your HF token from your original ticket to mask out sensitive data)
