[dependabot[bot]]

Bumps jaxlib from 0.1.61 to 0.1.68.

Changelog

Sourced from jaxlib's changelog.

jaxlib 0.1.61 (February 12 2021)

jaxlib 0.1.60 (Febuary 3 2021)

• Bug fixes:
  • Fixed a memory leak when converting CPU DeviceArrays to NumPy arrays. The memory leak was present in jaxlib releases 0.1.58 and 0.1.59.
  • bool, int8, and uint8 are now considered safe to cast to bfloat16 NumPy extension type.

jax 0.2.9 (January 26 2021)

• GitHub commits.
• New features:
  • Extend the {mod}jax.experimental.loops module with support for pytrees. Improved error checking and error messages.
  • Add {func}jax.experimental.enable_x64 and {func}jax.experimental.disable_x64. These are context managers which allow X64 mode to be temporarily enabled/disabled within a session.
• Breaking changes:
  • {func}jax.ops.segment_sum now drops segment IDs that are out of range rather than wrapping them into the segment ID space. This was done for performance reasons.

jaxlib 0.1.59 (January 15 2021)

jax 0.2.8 (January 12 2021)

• GitHub commits.
• New features:
  • Add {func}jax.closure_convert for use with higher-order custom derivative functions. ({jax-issue}[#5244](https://github.com/google/jax/issues/5244))
  • Add {func}jax.experimental.host_callback.call to call a custom Python function on the host and return a result to the device computation. ({jax-issue}[#5243](https://github.com/google/jax/issues/5243))
• Bug fixes:
  • jax.numpy.arccosh now returns the same branch as numpy.arccosh for complex inputs ({jax-issue}[#5156](https://github.com/google/jax/issues/5156))
  • host_callback.id_tap now works for jax.pmap also. There is a optional parameter for id_tap and id_print to request that the device from which the value is tapped be passed as a keyword argument to the tap function ({jax-issue}[#5182](https://github.com/google/jax/issues/5182)).
• Breaking changes:
  • jax.numpy.pad now takes keyword arguments. Positional argument constant_values has been removed. In addition, passing unsupported keyword arguments raises an error.
  • Changes for {func}jax.experimental.host_callback.id_tap ({jax-issue}[#5243](https://github.com/google/jax/issues/5243)):
    • Removed support for kwargs for {func}jax.experimental.host_callback.id_tap. (This support has been deprecated for a few months.)
    • Changed the printing of tuples for {func}jax.experimental.host_callback.id_print to use '(' instead of '['.
