Getting Started
================

Setup
-----

Begin by creating a new Python environment or activating an existing one for working with the `piQture` library. You set up a Python virtual environment `venv` or a Conda environment and use `pip` or `conda` to install the `piQture` package.

Here's how you can create a conda environment and manage a Python environment:

.. code:: sh
# Create a new conda environment
conda create -n piqture_env python=3.x
# Activate the conda environment
conda activate piqture_env
Installation
------------

Once the Python environment is activated, the required `piQture` package can be installed using `pip`. You can install the latest version directly from PyPI.

.. code:: sh
pip install piqture
To create a development environment, and install `piQture` from source, you can refer to section :ref:`Install from Source <installation_from_source>`.

.. _installation_from_source:

Installation from Source
------------------------

To set up a development environment and install `piQture` from source, follow these steps:

1. Start by cloning the `piQture` repository from GitHub.

.. code:: sh
# Clone the GitHub repository.
git clone https://github.com/SaashaJoshi/piQture.git
2. Activate the Python environment and navigate to the `piQture` repository directory. Then, inside the Python environment, install the required dependencies from the `requirements.txt` configuration file.

.. code:: sh
# Install the required dependencies
pip install -r requirements.txt
3. Install `piQture` in editable mode to make changes to the source code.

.. code:: sh
# Install from source in editable mode
pip install -e .
Your development environment is set up, and `piQture` is installed from source. You can now start making changes to the code, running tests, and contributing to the project as a developer.

Welcome to piQture's documentation!
===================================

**piQture** is a Python and Qiskit-based toolkit designed to simplify the development, execution, and training of Quantum Machine Learning (QML) models tailored for image processing tasks. This library seamlessly integrates with the Qiskit SDK, providing a convenient and user-friendly workflow for leveraging the potential of quantum computing for advanced image processing.

Data Loader
============================

`piqture.data_loader.mnist_data_loader` module
-----------------------------------------------

This module provides a `load_mnist_dataset` function that simplifies loading the MNIST dataset for machine learning and deep learning experiments. It supports custom batch sizes, label selection, image resizing, and normalization options.

.. automodule:: piqture.data_loader.mnist_data_loader
:members:
:undoc-members:
:show-inheritance:

Overview
--------

The `load_mnist_dataset` function in this module is designed to streamline the process of loading and preparing the MNIST dataset for image-based machine learning models, especially those involving quantum machine learning or custom image processing workflows.

Features
--------

- Supports custom image resizing to specified dimensions.
- Optionally filters specific labels from the MNIST dataset.
- Integrates custom normalization using `MinMaxNormalization`.
- Provides separate training and testing DataLoaders.

.. note::

Make sure that the `torch` and `torchvision` libraries are installed, as these are used internally for dataset handling and transformations.

Function Documentation
----------------------

**`load_mnist_dataset`**

.. autofunction:: piqture.data_loader.mnist_data_loader.load_mnist_dataset

Usage Example
-------------

Here's an example of how to use the `load_mnist_dataset` function to load the MNIST dataset and apply custom configurations:

.. code-block:: python
from piqture.data_loader import mnist_data_loader
# Load MNIST dataset with custom configurations
train_loader, test_loader = mnist_data_loader.load_mnist_dataset(
img_size=(32, 32), # Resize images to 32x32
batch_size=64, # Set batch size to 64
labels=[0, 1, 2], # Include only labels 0, 1, and 2
normalize_min=0.0, # Normalize minimum value to 0.0
normalize_max=1.0 # Normalize maximum value to 1.0
)
# Print some batch information
for images, labels in train_loader:
print(f"Batch image shape: {images.shape}")
print(f"Batch labels: {labels}")
break
Parameters
----------

- **`img_size`** (*int* or *tuple[int, int]*, optional):
- Size to which MNIST images will be resized.
- If an integer, images will be resized to a square of that size.
- If a tuple, it should specify `(height, width)` for the images.
- **Default:** `28` (images are resized to 28x28 pixels).

- **`batch_size`** (*int*, optional):
- Specifies the number of samples per batch for training and testing DataLoaders.
- If not specified, the batch size defaults to `1`.

- **`labels`** (*list[int]*, optional):
- A list of integers representing the labels to include in the dataset.
- For example, setting `labels=[0, 1]` will include images of digits 0 and 1 only.

- **`normalize_min`** (*float*, optional):
- Minimum value for pixel normalization.
- **Default:** `None` (no normalization).

- **`normalize_max`** (*float*, optional):
- Maximum value for pixel normalization.
- **Default:** `None` (no normalization).

Returns
-------

- **`Tuple[torch.utils.data.DataLoader, torch.utils.data.DataLoader]`**:
- A tuple containing:
- **Training DataLoader**: A PyTorch DataLoader for training data.
- **Testing DataLoader**: A PyTorch DataLoader for testing data.

Related Functions and Classes
-----------------------------

**`collate_fn`**

The `collate_fn` function is used to filter and organize batches based on the specified `labels`. It only includes images that match the desired labels.

.. autofunction:: piqture.data_loader.mnist_data_loader.collate_fn

Dependencies
------------

- **torch**: Required for creating PyTorch DataLoaders.
- **torchvision**: Required for dataset loading and transformations.
- **piqture.transforms.MinMaxNormalization**: Custom normalization transform available in the `piqture.transforms` module.

Handling Edge Cases
-------------------

The function performs type checking and validation to ensure that the input parameters are valid:

- **`img_size`**: Raises a `TypeError` if the value is not of type `int` or `tuple[int, int]`.
- **`batch_size`**: Raises a `TypeError` if the value is not an integer.
- **`labels`**: Raises a `TypeError` if the value is not a list.

Refer to the `source code <https://github.com/SaashaJoshi/piqture>`_ for additional implementation details and advanced configurations.
