Welcome to the captivating world of vision-language foundation models! Today we’ll delve into the ins and outs of using the InternVL-14B model, which seamlessly integrates image and text data processing for a variety of tasks. Whether you’re interested in zero-shot classification, image-text retrieval, or generating captions, this guide will provide you with everything you need to get started.

Getting Started with InternVL-14B

The InternVL-14B model is a state-of-the-art framework designed for multitasking across vision and language domains. Before jumping into the code, let’s check out the essential components.

Model Specifications

• Model Type: Vision-Language Foundation Model
• Parameters: 14 Billion
• Image Size: 224 x 224
• Pretraining Dataset: LAION-en, LAION-COCO, COYO, CC12M, CC3M, SBU, Wukong, LAION-multi

Installation

To leverage the capabilities of InternVL-14B, you’ll need to have PyTorch and Transformers libraries installed in your environment. Ensure you have the following:

• PyTorch
• Transformers

Using the Model

Now, let’s break down the Python code necessary to implement the InternVL-14B model. You can think of using this model like preparing a gourmet meal. Each ingredient (the code) adds complexity but is essential for making a delicious dish (outcome).

The Code

import torch
from PIL import Image
from transformers import AutoModel, CLIPImageProcessor, AutoTokenizer

# Load the model
model = AutoModel.from_pretrained(
    'OpenGVLab/InternVL-14B-224px',
    torch_dtype=torch.bfloat16,
    low_cpu_mem_usage=True,
    trust_remote_code=True
).cuda().eval()

image_processor = CLIPImageProcessor.from_pretrained('OpenGVLab/InternVL-14B-224px')
tokenizer = AutoTokenizer.from_pretrained('OpenGVLab/InternVL-14B-224px', use_fast=False, add_eos_token=True)
tokenizer.pad_token_id = 0  # essential setting

# Preparing images
images = [
    Image.open('examples/image1.jpg').convert('RGB'),
    Image.open('examples/image2.jpg').convert('RGB'),
    Image.open('examples/image3.jpg').convert('RGB')
]
prefix = "summarize: "
texts = [
    prefix + "a photo of a red panda",  # English
    prefix + "一张熊猫的照片",  # Chinese
    prefix + "二匹の猫の写真"  # Japanese
]

# Processing image values
pixel_values = image_processor(images=images, return_tensors='pt').pixel_values
pixel_values = pixel_values.to(torch.bfloat16).cuda()
input_ids = tokenizer(texts, return_tensors='pt', max_length=80, truncation=True, padding='max_length').input_ids.cuda()

# Make predictions
logits_per_image, logits_per_text = model(image=pixel_values, text=input_ids, mode='InternVL-C')
probs = logits_per_image.softmax(dim=-1)

Analogy Explanation

Imagine you are painting a masterpiece. Each brush stroke symbolizes the lines of code you write. The images are the canvas, and the captions are the colors adding depth and texture to your artwork. In our code, we first load the canvas (images) and the paintbrush (model) before blending colors (processing text) to create a stunning visual interpretative piece!

Troubleshooting

Here are some common issues you might face and tips to resolve them:

• Model Not Loading: Make sure your internet connection is active, and the model name is correctly typed.
• CUDA Errors: Ensure your CUDA version is compatible with the installed PyTorch version.
• Image Processing Issues: Verify that the image paths provided are correct, and that the images are in the right format.
• Tokenization Problems: Ensure that the tokenizer.pad_token_id is set to 0, as omitting it may cause abnormal results.
