Welcome to our step-by-step guide on leveraging the power of FasterViT for your vision tasks! In this article, we’ll cover how to install, use, and troubleshoot the FasterViT framework. Let’s dive in!

Understanding FasterViT

FasterViT excels in achieving state-of-the-art performance in image classification without requiring additional training data. To comprehend its functionality, let’s consider the following analogy:

Imagine FasterViT as a skilled librarian organizing books in a vast library. The librarian implements a unique filing system, enabling accurate and rapid access to both new books and those tucked away in the back. This filing system represents the Hierarchical Attention (HAT) mechanism, which connects disparate sections of the library for efficient retrieval based on user needs (or, in technical terms, cross-window carrier tokens).

Quick Start Guide

The following steps will help you set up FasterViT and get started on your image classification tasks smoothly.

Installation

• Make sure you have Python installed on your system.
• Install the FasterViT package using pip:

pip install fastervit

• If you previously installed FasterViT, upgrade to the latest version:

pip install fastervit==0.9.8

Using Pre-trained Models

Once installed, you can import a pre-trained FasterViT model with just one line of code:

from fastervit import create_model

To create a FasterViT-0 model, use the following code:

model = create_model('faster_vit_0_224', pretrained=True, model_path='tmp/faster_vit_0.pth.tar')

Running Inference

By preparing a dummy input image, you can execute inference:

import torch
image = torch.rand(1, 3, 224, 224)
output = model(image)  # Resulting shape: torch.Size([1, 1000])

Troubleshooting

If you encounter issues during installation or execution, consider the following:

• Ensure you’re using an updated version of NVIDIA TensorRT, as specified in the documentation.
• If you receive errors relating to missing dependencies, double-check that you have installed all required Python packages.
• In case of inconsistent model weights, re-initialize the model or download fresh pre-trained weights.
