This repository contains code for fine-tuning OpenAI's Contrastive Language–Image Pretraining (CLIP) model on a custom dataset. In this example, we use the Indian Fashion Apparel Dataset available on Kaggle.

The dataset consists of 106K images and 15 unique cloth categories. There's an equal distribution of the classes in the validation and the test set consisting of 500 samples per class for fine-grained classification of Indian ethnic clothes.

The CLIP model is designed to understand images in context with natural language. By training the model on a large number of images and their associated texts, CLIP learns to generate meaningful embeddings for both images and texts that are aligned in semantic space.

The code in this repository demonstrates how to fine-tune the CLIP model on a Indofashion dataset. This is done to adapt the pre-trained CLIP model to better understand specific domains or types of data that may not be well-covered in its original training set.

Before you begin, ensure you have met the following requirements:

• Python 3.6 or later
• PyTorch 1.7.1 or later
• transformers and clip libraries installed
• Access to a GPU is recommended but not required

The dataset used in this example is the Indian Fashion Apparel Dataset, available on Kaggle. Modify the image_path and json_path with your own and you're good to go.

Running the Code The main script for training the model is fine_tune_clip.py. This script loads the CLIP model, sets up a DataLoader for the dataset, and fine-tunes the model using backpropagation and gradient descent.

To run the script, navigate to the repository directory and enter:

python indofashion_clip.py

The script will run for a number of epochs specified by the num_epochs variable. The batch size and learning rate can be modified by changing the batch_size and lr parameters in the DataLoader and optimizer setup respectively.
