How to use ybelkada/bloom-1b7-8bit with Transformers:
# Use a pipeline as a high-level helper
from transformers import pipeline
pipe = pipeline("text-generation", model="ybelkada/bloom-1b7-8bit") # Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM
tokenizer = AutoTokenizer.from_pretrained("ybelkada/bloom-1b7-8bit")
model = AutoModelForCausalLM.from_pretrained("ybelkada/bloom-1b7-8bit")How to use ybelkada/bloom-1b7-8bit with vLLM:
# Install vLLM from pip:
pip install vllm
# Start the vLLM server:

This repository contains 8bit weights of bloom-1b7 model. You can load this model using transformers==4.28.0 and bitsandbytes>0.37.2 out of the box !
# pip install accelerate bitsandbytes
from transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("ybelkada/bloom-1b7-8bit")
First, make sure you are using transformers & bitsandbytes versions stated above. Then load your 8bit model as usual using load_in_8bit=True!
# pip install accelerate bitsandbytes
from transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("bigscience/bloom-1b7", device_map="auto", load_in_8bit=True)
Then just call push_to_hub method or save_pretrained method if you want to save your 8bit model locally
model.push_to_hub("{your_username}/bloom-1b7-8bit")
That's it!

Inside the state dict of the model (pytorch_model.bin file) you have
