[bioone]

i try the fllow code： `from transformers import AutoConfig, AutoModelForCausalLM

model_name = 'togethercomputer/evo-1-8k-base'

model_config = AutoConfig.from_pretrained(model_name, trust_remote_code=True) model_config.use_cache = True

model = AutoModelForCausalLM.from_pretrained( model_name, config=model_config, trust_remote_code=True, )`

raise error ：AssertionError: rotary_emb is not installed

however，the rotary_emb v0,1 installed，flash attentation also installed

can you share more info / stack trace? It might be the flash attention version.

I believe the source of this error is this line in flash-attention codebase. In my case, the import statement encapsulated in the try-except block failed with the following error: ModuleNotFoundError: No module named 'triton'. Installing triton fixed the problem.
