Welcome to our guide on JAXopt—a tool designed to streamline the process of optimization in machine learning. With its recent shift into maintenance mode as it’s being merged into Optax, it’s important to discuss how you can make the most out of its current capabilities while understanding its installation process.

What is JAXopt?

JAXopt provides hardware-accelerated, batchable, and differentiable optimizers that work seamlessly with JAX. Think of JAXopt as your particularly skilled engineer who can work on multiple projects at once, efficiently managing different optimization tasks without breaking a sweat!

Key Features of JAXopt

• Hardware Accelerated: Allows implementations to run on GPU, TPU, and CPU.
• Batchable: Automatically vectorizes multiple instances of the same optimization problem using JAX’s vmap.
• Differentiable: Solutions can be differentiated with respect to their inputs, either implicitly or through autodiff of unrolled algorithm iterations.

Installation Steps

Ready to dive in? Here’s how to install JAXopt based on your needs:

1. Installing the Latest Release

To install the latest stable version of JAXopt, simply run the command below in your terminal:

pip install jaxopt

2. Installing the Development Version

If you’re interested in the cutting-edge features, you can install the development version using this command:
