jax.numpy package
|
|
=================
|
|
|
|
.. currentmodule:: jax.numpy
|
|
|
|
.. automodule:: jax.numpy
|
|
|
|
Implements the NumPy API, using the primitives in :mod:`jax.lax`.
|
|
|
|
While JAX tries to follow the NumPy API as closely as possible, sometimes JAX
|
|
cannot follow NumPy exactly.
|
|
|
|
* Notably, since JAX arrays are immutable, NumPy APIs that mutate arrays
|
|
in-place cannot be implemented in JAX. However, often JAX is able to provide a
|
|
alternative API that is purely functional. For example, instead of in-place
|
|
array updates (:code:`x[i] = y`), JAX provides an alternative pure indexed
|
|
update function :func:`jax.ops.index_update`.
|
|
|
|
* NumPy is very aggressive at promoting values to :code:`float64` type. JAX
|
|
sometimes is less aggressive about type promotion.
|
|
|
|
A small number of NumPy operations that have data-dependent output shapes are
|
|
incompatible with :func:`jax.jit` compilation. The XLA compiler requires that
|
|
shapes of arrays be known at compile time. While it would be possible to provide
|
|
a JAX implementation of an API such as :func:`numpy.nonzero`, we would be unable
|
|
to JIT-compile it because the shape of its output depends on the contents of the
|
|
input data.
|
|
|
|
Not every function in NumPy is implemented; contributions are welcome!
