* ENH: Faster numpy.load (try/except _filter_header) (#22916)Michael2023-01-131-4/+18
| | | | | | | This pull requests speeds up numpy.load. Since _filter_header is quite a bottleneck, we only run it if we must. Users will get a warning if they have a legacy Numpy file so that they can save it again for faster loading. Main discussion and benchmarks see #22898 Co-authored-by: Sebastian Berg <sebastian@sipsolutions.net>

| * MAINT: Ensure graceful handling of large header sizesSebastian Berg2022-10-061-9/+50
| | | | | | | | | | | | | | | | | | This ensures graceful handling of large header files. Unfortunately, it may be a bit inconvenient for users, thus the new kwarg and the work-around of also accepting allow-pickle.

| | | Follow up to [this commit](https://github.com/numpy/numpy/commit/36f71788620bb17d123669cf03f086fb2b87b3a8), which missed the second pronoun in this sentence.

* BUG: np.load does not handle empty array with an empty descr (#15397)Sha Liu2020-01-271-7/+10
| | | | | | | The bug occurs since numpy 1.16. Before that empty descr corresponds to `np.dtype([])`. This fixes the problem by following numpy 1.15's behavior. Closes gh-15396

| | | | | | | | | | | | | | | | This version encodes the dtype as utf8 instead of latin1. Unfortunately we need to create a new version to make this change, because we did not limit ourselves to ASCII in versions 1 and 2. Fixes gh-7391

* BUG: Fix errors in string formatting while producing an errorEric Wieser2019-03-021-13/+13
| | | | | | | | | | `"Invalid version %r" % (1, 2)` would fail with `TypeError: not all arguments converted during string formatting` The `Header is not a dictionary` error had a similar problem. Fixed by changing this entire function to use `.format` in place of `%`, which does not have this gotcha. Found using LGTM.com
* MAINT: Move pickle import to numpy.compatCharles Harris2019-02-211-2/+1
| | | | | | | The pickle module was being imported from numpy.core.numeric. It was defined there in order to use pickle5 when available in Python3 and cpickle in Python2. The numpy.compat module seems a better place for that.
