How to Get Started with InternVL 2.0: A Guide for Developers

Welcome to the world of InternVL 2.0, a state-of-the-art multimodal large language model designed to seamlessly integrate text, images, and video analysis! In this guide, we’ll walk you through the steps to utilize this powerful model, how to implement it, and troubleshoot issues you might encounter along the way.

Understanding InternVL 2.0: The Smart Assistant

Imagine you have a super-smart assistant that can not only read and write but also understand images and videos, all at once. InternVL 2.0 embodies this idea perfectly, utilizing 1 billion to 108 billion parameters across its various models, enabling it to handle tasks from document interpretation to video content comprehension seamlessly.

Quick Start: Load and Use InternVL 2.0

Here’s how to get started with the InternVL2-1B model quickly:

• Install the required libraries: Before running the model, ensure you have the specified version of transformers:

pip install transformers==4.37.2

• Set up the model: Load the model using the code below:

python
import torch
from transformers import AutoTokenizer, AutoModel

path = "OpenGVLab/InternVL2-1B"
model = AutoModel.from_pretrained(
    path,
    torch_dtype=torch.bfloat16,
    low_cpu_mem_usage=True,
    use_flash_attn=True,
    trust_remote_code=True
).eval().cuda()

Making Predictions: A Walkthrough

Once your model is loaded, it’s time to make predictions. Consider how a chef creates a dish: each ingredient represents an input—be it text, image, or video—and the final dish is your model’s output—the insights and answers you need!

Here’s a simple example of how to chat with the model using an image:

pixel_values = load_image("examples/image1.jpg", max_num=12).to(torch.bfloat16).cuda()
response = model.chat(tokenizer, pixel_values, question="Please describe the image in detail.")

Troubleshooting Common Issues

Even the best ingredients can sometimes lead to unexpected results. Here are some common issues and their solutions:

• Import Error: If you encounter an import error, ensure all necessary packages are installed, and versions match the specified requirements.
• CUDA Errors: If your model runs into CUDA memory errors, consider reducing the batch size or using model quantization techniques.
• Unexpected Outputs: Given the model’s probabilistic nature, outputs can vary. Try changing the input or rephrasing queries for different results.
