Bumps jax from 0.2.8 to 0.2.18.

Changelog

Sourced from jax's changelog.

jax 0.2.18 (July 21 2021)

• GitHub commits.

• Breaking changes:

  • Support for Python 3.6 has been dropped, per the deprecation policy. Please upgrade to a supported Python version.
  • The minimum jaxlib version is now 0.1.69.
  • The backend argument to {py:func}jax.dlpack.from_dlpack has been removed.

• New features:

  • Added a polar decomposition ({py:func}jax.scipy.linalg.polar).

• Bug fixes:

  • Tightened the checks for lax.argmin and lax.argmax to ensure they are not used with invalid axis value, or with an empty reduction dimension. ({jax-issue}[#7196](https://github.com/google/jax/issues/7196))

jaxlib 0.1.69 (July 9 2021)

• Fix bugs in TFRT CPU backend that results in incorrect results.

jax 0.2.17 (July 9 2021)

• GitHub commits.
• Bug fixes:
  • Default to the older "stream_executor" CPU runtime for jaxlib <= 0.1.68 to work around #7229, which caused wrong outputs on CPU due to a concurrency problem.
• New features:
  • New SciPy function {py:func}jax.scipy.special.sph_harm.
  • Reverse-mode autodiff functions ({func}jax.grad, {func}jax.value_and_grad, {func}jax.vjp, and {func}jax.linear_transpose) support a parameter that indicates which named axes should be summed over in the backward pass if they were broadcasted over in the forward pass. This enables use of these APIs in a non-per-example way inside maps (initially only {func}jax.experimental.maps.xmap) ({jax-issue}[#6950](https://github.com/google/jax/issues/6950)).

jax 0.2.16 (June 23 2021)

• GitHub commits.

jax 0.2.15 (June 23 2021)

• GitHub commits.
• New features:
  • #7042 Turned on TFRT CPU backend with significant dispatch performance improvements on CPU.
  • The {func}jax2tf.convert supports inequalities and min/max for booleans ({jax-issue}[#6956](https://github.com/google/jax/issues/6956)).
