* trailing-whitespace
* dangerous-default-value. None of these appear to be bugs in practice, but the potential for accidentally mutating the default value is there, and the cost of avoiding the problem is small.
* invalid-envvar-default. Pass strings as getenv() defaults.
* unnecessary-semicolon. Use tuples instead for this one-liner.
* invalid-hash-returned. Raise an exception rather than asserting false.
* pointless-string-statement. Use comments instead.
* unreachable. Use @unittest.skip() decorator rather than raising as first line in test.
* logging-not-lazy. Make the logging lazy.
* bad-format-string-type. Use f-string instead.
* subprocess-run-check. Pass check=...
PiperOrigin-RevId: 400858477
fixed some bugs in the bicgstab method and adjusted tolerance for scipy comparison
fixed flake8
added some tests for gradients, fixed symmetry checks, modified lax.cond -> jnp.where
comment out gmres grad check, to be addressed on future PR
increasing tolerance for bicgstab grad test
change to order 1 checks for bicgstab (gmres still fails in order 1) for internal CI check
remove grad checks for now
changing tolerance to pass numpy comparison test
The permutation is more efficiently computed during the decomposition on TPU, and the only use case that would not require us to compute it would be for evaluating determinants.

Now we check tree structure and leaf shapes separately. This allow us to
support pytrees that either don't define equality or that define it
inconsistently (e.g., elementwise like NumPy) with builtin data structures like
list/dict.
* Use precision=HIGHEST in expm repeated squaring
This will improve the output accuracy on TPUs, and doesn't currently affect other platforms.
Also remove a spurious duplicate line.
* Also use HIGHEST precision in Pade approximants
* Update linalg.py
* Update linalg.py
* Implement Frechet derivatives for expm.
* Update expm to use the current custom gradients API.
Make some stylistic fixes.
