Need help performance issues transformers.AutoModelForCausalLM.from_pretrained( 'mosaicml/mpt-7b-instruct'

I’m building a chatbot using the following python code

Required imports

import os
import streamlit as st
import torch
import transformers
from torch import cuda, bfloat16
from transformers import StoppingCriteria, StoppingCriteriaList

Checking if CUDA is available

device = f’cuda:{cuda.current_device()}’ if cuda.is_available() else ‘cpu’

Print if CUDA is available or not

if cuda.is_available():
print(“CUDA is available. PyTorch is using GPU.”)
print(“Device ID:”, device)
print(“Device Name:”, torch.cuda.get_device_name(device))
print(“CUDA is not available. PyTorch is using CPU.”)

Model Loading

model = transformers.AutoModelForCausalLM.from_pretrained(
‘mosaicml/mpt-7b-instruct’, # replace with path to your model directory

Move the model to GPU device


tokenizer = transformers.AutoTokenizer.from_pretrained(“EleutherAI/gpt-neox-20b”)

Stopping Criteria

stop_token_ids = tokenizer.convert_tokens_to_ids([“”])

class StopOnTokens(StoppingCriteria):
def call(self, input_ids: torch.LongTensor, scores: torch.FloatTensor, **kwargs) → bool:
for stop_id in stop_token_ids:
if input_ids[0][-1] == stop_id:
return True
return False

stopping_criteria = StoppingCriteriaList([StopOnTokens()])

HF Pipeline

generate_text = transformers.pipeline(
model=model, tokenizer=tokenizer,


st.title(‘:robot: Jarvis Assistant’)

Define a conversation history

conversation_history = [
“Question: Jarvis, do a system check.\nAnswer: Sir, all systems are functional.\n”,
“Question: Jarvis, what’s our status?\nAnswer: Sir, all systems are operational and ready for deployment.\n”,
“Question: Jarvis, where are we?\nAnswer: Sir, you are currently in your Malibu residence.\n”,
“Question: Jarvis, activate the security protocols.\nAnswer: Security protocols activated, sir.\n”,
“Question: Jarvis, what’s the weather like today?\nAnswer: Sir, the weather today is sunny with a high of 75.\n”,
“Question: Jarvis, run a diagnostic.\nAnswer: Running diagnostic, sir. All systems are functioning optimally.\n”,
“Question: Jarvis, what’s our ETA?\nAnswer: Sir, we will arrive at our destination in 15 minutes.\n”,

Prompt Text Box

prompt = st.text_input(‘Ask me anything’)

if we hit enter do this

if prompt:
# Add the new question to the conversation history
conversation_history.append(f"Question: Jarvis, {prompt}\nAnswer: ")

# Pass the conversation history to the generate_text pipeline
response = generate_text("".join(conversation_history))

# Extract the model's response
model_response = response[0]['generated_text'].split("Answer: ")[-1]

# Add the model's response to the conversation history

# Print the model's response

But it keeps saying it’s using CPU not GPU even tho GPU is available

Here is the output

CUDA is available. PyTorch is using GPU.
Device ID: cuda:0
Device Name: NVIDIA GeForce RTX 4090 Laptop GPU
You are using config.init_device=‘cpu’, but you can also use config.init_device=“meta” with Composer + FSDP for fast initialization.

Thanks, Any help would be Appreciated.
