Welcome to the world of visual question answering (VQA) with InternLM-XComposer 2.5! This powerful model enables the integration of text and image comprehension, allowing you to analyze video frames and images effectively. In this blog, we’ll walk you through using the InternLM-XComposer, exploring its capabilities, and troubleshooting common issues. Let’s dive in!

What is InternLM-XComposer 2.5?

InternLM-XComposer 2.5 is a state-of-the-art model designed for text-image comprehension and composition, reaching the impressive capabilities akin to GPT-4V while utilizing a backend of just 7 billion parameters. With training on 24,000 interleaved image-text contexts, it can seamlessly extend to 96,000 long contexts through RoPE extrapolation, providing it with remarkable effectiveness in tasks demanding extensive input and output.

Quick Start Guide

To get started with the InternLM-XComposer 2.5 model, follow these simple steps:

• Import Required Libraries: First, ensure you have the necessary packages.
• Load the Model: You can load the model with the code provided below:

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

# Set the path to the model
ckpt_path = "internlm/internlm-xcomposer2d5-7b"

# Load the tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(ckpt_path, trust_remote_code=True).cuda()
model = AutoModelForCausalLM.from_pretrained(ckpt_path, torch_dtype=torch.bfloat16, trust_remote_code=True).cuda()
model = model.eval()

Using InternLM-XComposer 2.5

Let’s take a deeper look into how you can engage with the model. Below, we’ll explore how to analyze video content and images with examples.

Analyzing Videos

Imagine watching a thrilling sports event and wanting to describe the action in detail. With InternLM-XComposer, you can feed the model video frames to extract rich narratives!

query = "Here are some frames of a video. Describe this video in detail."
image = "path/to/your/video.mp4"

with torch.autocast(device_type='cuda', dtype=torch.float16):
    response, _ = model.chat(tokenizer, query, image, do_sample=False, num_beams=3, use_meta=True)

print(response)

In this example, the model processes the video clips, similar to a sports commentator breaking down a match track by track, detailing the athletes’ performances and emotional highs.

Multi-Image Analysis

You can also compare images for decision-making, like choosing the best car to buy based on their attributes.

query = "Image1; Image2; Image3; Analyze their advantages and weaknesses one by one."
image = ["path/to/image1.jpg", "path/to/image2.jpg", "path/to/image3.jpg"]

with torch.autocast(device_type='cuda', dtype=torch.float16):
    response, _ = model.chat(tokenizer, query, image, do_sample=False, num_beams=3, use_meta=True)

print(response)

This is akin to having a knowledgeable friend help you weigh the pros and cons of a variety of choices, guiding you towards a thoughtful decision.

Troubleshooting Common Issues

While utilizing InternLM-XComposer, you might encounter a few hiccups. Here are some troubleshooting tips:

• Out of Memory Errors (OOM): If you run into OOM errors when loading model weights, consider using less memory-intensive settings, such as torch_dtype=torch.float32 instead of torch.bfloat16.
• Installation Issues: Make sure you have the latest versions of transformers and torch installed. You can install or update them using pip.
• Model Not Found: If the model fails to load, check your ckpt_path and ensure your internet connection is stable.
