* BUG: use explicit einsum_path whenever it is given (#21639)Toshiki Kataoka2022-06-091-4/+16
| | | | | | | | | | | * BUG: use explicit einsum_path whenever it is given For example, allow user to specify unary contractions in binary einsum as described in #20962. The commit also adds a sanity check on user-specified einsum_path. * fix lint * MAINT: refactor logic with explicit_einsum_path

* DOC: Misc numpydoc format fixesMatthias Bussonnier2021-01-271-5/+3
| | | | | | | | | Via prototype docstring autoreformatter; and cherry-picked to mostly include spacing issues around colons in parameters and see also. When no space is present numpydoc tend to miss-parse those sections A couple of typos are fixed as well.
* DOC: add references to einops and opt_einsumAlex Rogozhnikov2020-10-031-0/+11
| | | | | | Following discussion in mailing list, this PR adds mentions to third-party libs einops and opt_einsum to einsum documentation

* BUG: numpy.einsum indexing arrays now accept numpy int type (gh-16080)Ryan2020-05-161-8/+13
| | | | | | | | | | | | | * Using PyArray_PyIntAsIntp helper function instead * TST: add tests for einsum numpy int and bool list subscripts Added tests to check that einsum accepts numpy int64 types and rejects bool. Rejecting bools is new behaviour in subscript lists. I changed ValueError to TypeError on line 2496 in multiarraymodule.c as it is more appropriate. I also modified einsumfunc.py to have the same behaviour as in the C file when checking subscript list. (Reject bools but accept anything else from operator.index()) Closes gh-15961
* STY: use 'yield from <expr>' for simple cases (#15444)Mike Taves2020-01-271-2/+1
| | | | | | | | | This PR uses simple cases of PEP 380 to rewrite: for v in g: yield v into: yield from <expr>
* MAINT: Replace basestring with str.Charles Harris2020-01-231-4/+3

| | | | Now that 2.7 is gone, there is no need to pop manually from kwarg dictionaries.
* MAINT: Remove unnecessary 'from __future__ import ...' statementsJon Dufresne2020-01-031-2/+0
| | | | | As numpy is Python 3 only, these import statements are now unnecessary and don't alter runtime behavior.

* MAINT: set __module__ for more array_function_dispatch usesStephan Hoyer2018-10-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed a few more functions using ``array_function_dispatch`` where I had not set the module, using this script:: import types def check_module(module): for name in dir(module): item = getattr(module, name) if isinstance(item, types.FunctionType): print(f'{item.__module__}.{item.__name__}') >>> import numpy >>> check_module(numpy) ... Note that functions without overrides like ``numpy.ones`` still display the module in which they are defined, e.g., ``numpy.core.numeric.ones``. We should probably fix that, too, probably most cleanly adding a decorator that sets ``__module__``, e.g., def set_module(module): def decorator(func): func.__module__ = module return func return decorator ... @set_module('numpy') def ones(shape, dtype=None, order='C'): ...

* MAINT: Make einsum optimize default to False.Charles Harris2018-08-121-2/+2
| | | | | | | | | False is the documented value and the value used in 1.14, but 1.15.0 was turning optimization on when there were more than two arguments, resulting in slowdowns for small matrices. This choice can be revisited as the einsum optimization code matures. Closes #11714.
