lazyqml 0.1.23

LazyQML is a Python library designed to streamline, automate, and accelerate experimentation with Quantum Machine Learning (QML) architectures, right on classical computers.

With LazyQML, you can:

• 🛠️ Build, test, and benchmark QML models with minimal effort.

• ⚡ Compare different QML architectures, hyperparameters seamlessly.

• 🧠 Gather knowledge about the most suitable architecture for your problem.

✨ Why LazyQML?

• Rapid Prototyping: Experiment with different QML models using just a few lines of code.

• Automated Benchmarking: Evaluate performance and trade-offs across architectures effortlessly.

• Flexible & Modular: From basic quantum circuits to hybrid quantum-classical models—LazyQML has you covered.

Documentation

For detailed usage instructions, API reference, and code examples, please refer to the official LazyQML documentation.

Requirements

• Python >= 3.12

❗❗ This library is only supported by Linux Systems. It doesn't support Windows nor MacOS. Only supports CUDA compatible devices.

Installation

To install lazyqml, run this command in your terminal:

pip install lazyqml

This is the preferred method to install lazyqml, as it will always install the most recent stable release.

If you don't have pip installed, this Python installation guide can guide you through the process.

From sources

To install lazyqml from sources, run this command in your terminal:

pip install git+https://github.com/QHPC-SP-Research-Lab/LazyQML

Example

from sklearn.datasets import load_iris
from lazyqml          import QuantumClassifier
from lazyqml.Global   import Embedding, Ansatzs, Model

# Load data
data = load_iris()
X = data.data
y = data.target

classifier = QuantumClassifier(nqubits={4}, classifiers={Model.QNN, Model.QSVM}, embeddings={Embedding.ZZ, Embedding.ZZ_LOCAL}, epochs=10)

# Fit and predict
classifier.fit(X=X, y=y, test_size=0.4)
