Hi @bweinstein123
The snippet below should enable multi-GPU inference:

+ import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
 
model_id = "mistralai/Mixtral-8x7B-v0.1"
tokenizer = AutoTokenizer.from_pretrained(model_id)
+ model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.float16, device_map="auto")
- model = AutoModelForCausalLM.from_pretrained(model_id)
- model.half().cuda()

inputs = tokenizer(text, return_tensors="pt")
inputs_gpu = {key: value.to("cuda") for key, value in inputs.items()}

outputs = model.generate(**inputs_gpu, max_new_tokens=500)

Hi @ybelkada
I try this code, get the error like below:

@barbery Did you solve this error? If so, can you share how?

No, I have no idea how to solve it @ofir408
