In this user-friendly guide, we will walk you through how to work with the Visual BERT model finetuned on the Easy VQA dataset. This model opens up exciting possibilities for visual question answering tasks. It enables computers to understand images while also interpreting natural language questions, a feat that mimics human reasoning.

What Is Visual BERT?

Visual BERT is a multi-modal vision and language model that performs tasks such as visual question answering, multiple-choice, and visual reasoning.

For further insights into Visual BERT, refer to the documentation.

Understanding the Easy VQA Dataset

The Easy VQA dataset serves as a training ground for our model. Imagine it as a set of flashcards with images that depict very simplistic shapes—rectangles, triangles, and circles—all dyed in a handful of colors. Each flashcard is linked to questions like “What shape is this?” or “What color is the triangle?”

• Each instance in the dataset comprises:
  • A question about the image.
  • The answer (label).
  • The ID of the related image.
• Possible questions include:
  • What is the blue shape?
  • What color is the triangle?
  • Is there a red shape?
• Answers can be:
  • The three possible shapes.
  • The eight possible colors.
  • Yes or No.

How to Use Visual BERT with Easy VQA

To get started, you’ll need to load the image processor and the model. Below is the Python code needed:

python
processor = ViltProcessor.from_pretrained('dandelin/vilt-b32-finetuned-vqa')
model = VisualBertForQuestionAnswering.from_pretrained('daki97/visualbert-finetuned-easy-vqa')

This code snippet can be compared to a chef reaching for their go-to ingredients. The processor acts like the sous chef who prepares the ingredients (images) for the main dish (the model) to serve various questions effectively.

Troubleshooting

Running into issues? Here are some common troubleshooting tips:

• Ensure that you have installed the Easy VQA package correctly with the command:

  pip install easy_vqa

• If you face any problems with data loading, check if you have the correct paths set for your images and questions.
• For any unexpected behavior, revisit the model’s configurations and ensure you are using the correct pretrained weights.
