Hardware accelerated, batchable and differentiable optimizers in JAX.

  • Hardware accelerated: our implementations run on GPU and TPU, in addition to CPU.
  • Batchable: multiple instances of the same optimization problem can be automatically vectorized using JAX's vmap.
  • Differentiable: optimization problem solutions can be differentiated with respect to their inputs either implicitly or via autodiff of unrolled algorithm iterations.


To install the latest release of JAXopt, use the following command:

$ pip install jaxopt

To install the development version, use the following command instead:

$ pip install git+https://github.com/google/jaxopt

Alternatively, it can be installed from sources with the following command:

$ python setup.py install
