RuntimeError: FlashAttention backward for head dim > 64 requires A100 or H100 GPUs as the implementation needs a large amount of shared memory.
Are it referring to the head dimension of vicuna-7b being more than 64?

I used A6000 for training, but I didn't have this issue, which flash-attention version are you using?
