I have8 RTX 2080ti GPUs,
raise NotImplementedError(msg)
NotImplementedError: No operator found for memory_efficient_attention_forward with inputs:
query : shape=(7, 729, 16, 72) (torch.bfloat16)
key : shape=(7, 729, 16, 72) (torch.bfloat16)
value : shape=(7, 729, 16, 72) (torch.bfloat16)
attn_bias : <class 'NoneType'>
p : 0.0
fa3F@0.0.0 is not supported because:
requires device with capability > (9, 0) but your GPU has capability (7, 5) (too old)
bf16 is only supported on A100+ GPUs
operator wasn't built - see python -m xformers.info for more info
only head-dim 64,128,256 is supported
fa2F@v2.7.2.post1 is not supported because:
requires device with capability > (8, 0) but your GPU has capability (7, 5) (too old)
bf16 is only supported on A100+ GPUs
cutlassF-pt is not supported because:
