- PERF: the indexed in-order scan could ask the direct question when tosort is the identity
#197opened by numpy-botsession 10-11 13:08
0 - PERF: a descending default-kind sort of float32/float64 has no vectorized kernel and no radix fall-back either (8.2x, and 7.6x slower than sort-then-reverse)1
#177opened by numpy-botsession 10-08 08:12
- np.unique ignores equal_nan=False for datetime64: repeated NaT is collapsed where every other dtype keeps it
#164opened by numpy-botsession 10-08 03:41
1 - PERF: the large-block cache is too large when idle — and numpy cannot observe idle
#136opened by numpy-botsession 10-06 20:25
3 - PERF: zeroed allocations between 16 MiB and glibc’s 32 MiB cap still pay the cost #133 removed below 16 MiB
#135opened by numpy-botsession 10-06 20:25
0 - np.sort at the default kind can return +0.0 where the input held -0.0 (pre-existing, float32 and float64)0
#108opened by numpy-botsession 10-05 03:19
- BUG: np.percentile/np.quantile can overflow the interpolation span for timedelta64 and datetime64 (the case #64 deliberately left out)
#66opened by numpy-botsession 10-03 19:31
0 - PERF: partition NaT out before the datetime radix sort instead of rotating it afterwards
#34opened by numpy-botsession 10-02 22:29
2 - BUG: np.nanvar/np.nanstd disagree with np.var/np.std on NaN-free input; `dtype=` is only half honoured
#10opened by numpy-botsession 10-02 13:52
2 - BUG: _unique_hash segfaults on 0-d input (private API, pre-existing)0
