The device you should use is either “cpu” or “mps” for Mac

Anyone managed to run it?

Macbook pro m2 32 gb ram - not enough?

The following works for me. The Python process seems to take ~21 GB when using float16 in my M1.

import requests
import torch
from PIL import Image
from transformers import AutoTokenizer, FuyuForCausalLM, FuyuImageProcessor, FuyuProcessor

device = "mps"

# Metal supports `bfloat16` in Sonoma, but it still doesn't work
dtype = torch.bfloat16 if device != "mps" else torch.float16

model_id = "adept/fuyu-8b"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = FuyuForCausalLM.from_pretrained(model_id, device_map=device, torch_dtype=dtype)
processor = FuyuProcessor(image_processor=FuyuImageProcessor(), tokenizer=tokenizer)

prompt = "Generate a coco-style caption.\n"
url = "https://huggingface.co/adept/fuyu-8b/resolve/main/bus.png"

image = Image.open(requests.get(url, stream=True).raw)

model_inputs = processor(text=prompt, images=[image])
model_inputs = {k: v.to(dtype=dtype if torch.is_floating_point(v) else v.dtype, device=device) for k,v in model_inputs.items()}
prompt_len = model_inputs["input_ids"].shape[-1]

generation_output = model.generate(**model_inputs, max_new_tokens=10)
print(tokenizer.decode(generation_output[0][prompt_len:], skip_special_tokens=True))

@pcuenq Which transformers version is this running with? I tried and when you're doing v.to(dtype=...) , v is a list of tensors. In order for that call to work v must have been a tensor.

model_inputs = processor(text=prompt, images=[image])
for k, v in model_inputs.items():
if isinstance(v, list):
model_inputs[k] = [item.to(dtype=dtype if torch.is_floating_point(item) else item.dtype, device=device) for item in v]
else:
model_inputs[k] = v.to(dtype=dtype if torch.is_floating_point(v) else v.dtype, device=device)

Works like this. The else is not needed on my part but I wanted to keep the original case as well.
