HuggingFacePipeline Llama2 load_in_4bit from_model_id the model has been loaded with `accelerate` and therefore cannot be moved to a specific device

đŸ€—Accelerate

Hello
Trying to load Llama2 model with the HuggingFacePipeline
In an AWS g5.4xlarge (1 Gpu-16Cpu-64GoCpu-24GoGpu) instance.
with the code below I have the below error.

I tried also
-With other type of instances
-Specifying 1 GPU
-Removing device-Auto
and I have the same errors.

I tried also just loading with
model = AutoModelForCausalLM.from_pretrained(“meta-llama/Llama-2-7b-chat-hf”, device_map=“auto”)
and this loads the model well.
I think is the pipeline issue or link between langchain & accelerate?

Any Idea to use the pipeline?
thanks
JD

It’s probably the pipeline on langchain side. Just like you said, loading with model = AutoModelForCausalLM.from_pretrained(“meta-llama/Llama-2-7b-chat-hf”, device_map=“auto”) works. There is nothing we can do on our side.

Juand-David, were you able to solve this issue? I’m facing the same error when I try to load the model into MLflow, and have taken out device-auto or any device specifications. Thanks!
