The Mixtral-8x7b-Instruct-v0.1 model is a powerful tool for language inference, optimized using OpenVINO™. In this guide, we will walk you through the steps to start using this model effectively while explaining key concepts in a user-friendly manner.

What is This Model?

The Mixtral-8x7b-Instruct-v0.1 model, created by Mistral AI, represents an updated variant designed for performance enhancements with weights compressed to INT8. Think of it like a suitcase that’s been packed to be as light as possible while still holding all the essentials you need for your trip.

Getting Started

Follow these steps to set up and run inference on the Mixtral-8x7b-Instruct-v0.1 model.

1. Prerequisites

• Ensure you have Python and pip installed.
• OpenVINO version should be 2024.2.0 or higher.
• Optimum Intel version should be 1.17.0 or higher.

2. Install Required Packages

For using Optimum Intel integration with the OpenVINO backend, install the required packages by executing:

pip install optimum[openvino]

3. Running Model Inference with Optimum Intel

Use the following code to run your inference:

from transformers import AutoTokenizer
from optimum.intel.openvino import OVModelForCausalLM

model_id = "OpenVINOmixtral-8x7b-instruct-v0.1-int8-ov"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = OVModelForCausalLM.from_pretrained(model_id)
inputs = tokenizer("What is OpenVINO?", return_tensors='pt')
outputs = model.generate(**inputs, max_length=200)
text = tokenizer.batch_decode(outputs)[0]
print(text)

In this code, you’re setting up a conversation with the model, asking “What is OpenVINO?” and the model responds just like a knowledgeable friend would in a chat—plugging in its understanding and generating a coherent answer.

4. Running Model Inference Using OpenVINO GenAI

If you prefer using the OpenVINO GenAI setup, follow these steps:

1. Install the required packages:

pip install openvino-genai huggingface_hub

2. Download the model from HuggingFace Hub:

import huggingface_hub as hf_hub

model_id = "OpenVINOmixtral-8x7b-instruct-v0.1-int8-ov"
model_path = "mixtral-8x7b-instruct-v0.1-int8-ov"
hf_hub.snapshot_download(model_id, local_dir=model_path)

3. Run the model inference:

import openvino_genai as ov_genai

device = "CPU"
pipe = ov_genai.LLMPipeline(model_path, device)
print(pipe.generate("What is OpenVINO?", max_length=200))

In essence, this is akin to turning on a really sophisticated library assistant who fetches the information you need in a timely manner.

Troubleshooting

If you encounter issues while running the model, here are some troubleshooting tips:

• Ensure that all package versions are correct and compatible.
• Check if your Python environment is properly set up to include the required libraries.
• If you experience memory issues, consider reducing the model’s maximum length during inference.
