Welcome to your guide on using the Qwen-VL model—Alibaba Cloud’s advanced visual multimodal machine learning model! This article will walk you through setup, usage, and troubleshooting so you can maximize the capabilities of Qwen-VL in your projects.

Getting Started with Qwen-VL

Before diving into using Qwen-VL, you need to ensure that your environment is correctly set up with the necessary dependencies. Here is what you’ll need:

• Python 3.8 or above
• PyTorch 2.0 or above
• CUDA 11.4 or above

Quickstart Setup

Let’s get your environment ready!

Install the required libraries and clone the necessary repository using the commands below:

pip install -r requirements.txt
pip install optimum
git clone https://github.com/JustinLin610/AutoGPTQ.git
cd AutoGPTQ
pip install -v .

Using Qwen-VL in Code

Think of using Qwen-VL like giving instructions to a highly trained chef. You need to provide the right ingredients (inputs like images and text) in a precise manner to get the best dish (output). Here’s how to input data into the model:

python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

torch.manual_seed(1234)

# Load the tokenizer
tokenizer = AutoTokenizer.from_pretrained("Qwen-Qwen-VL-Chat-Int4", trust_remote_code=True)

# Load the model using CUDA
model = AutoModelForCausalLM.from_pretrained("Qwen-Qwen-VL-Chat-Int4", device_map="cuda", trust_remote_code=True).eval()

# Input image and text query
query = tokenizer.from_list_format([{
    "image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen-VL/assets/demo.jpeg",
    "text": "",
}])
response, history = model.chat(tokenizer, query=query, history=None)

print(response)

# To continue the dialogue
response, history = model.chat(tokenizer, history=history)
print(response)

In this code, you set a manual seed for reproducibility, load the necessary tokenizer and model, and then input your data. The chef (model) will respond with the best output depending on your query (ingredients).

Troubleshooting Common Issues

It’s common to encounter a few bumps along the way. Here are some troubleshooting ideas:

• Environment Issues: Ensure you have the correct versions of Python, PyTorch, and CUDA. If installations fail, check your internet connection or permissions.
• Model Not Found: If the model cannot be found, verify you entered the correct name and ensure it is properly installed.
• CUDA Errors: If you face CUDA-related errors, make sure your GPU drivers are up to date and compatible with the version of PyTorch you’re using.
