Hello, guys!
I ran numba tests with macos Catalina 10.15.17, Intel-based CPU, Python 3.9.2 version and Numba 0.53.0rc3 and got the following:

Hi @AlexanderUp,

Many thanks for testing. It seems like all these errors are floating point related. Questions:

  • Which version of NumPy are you using?
  • Where did you get the packages in the environment from? (Mainly interested in Numba and NumPy and whether it’s conda or wheels).

Thanks for your help.

24

I tried to replicate this as I am also on Catalina 10.15.7 – but I have not been able to do so yet. Here are the commands I used to setup the environement and run the tests:

$ conda create -n numba_test -c numba numba=0.53.0rc3 python==3.9.2
...
$ conda activate numba_test
...
$ python3 -m numba.runtests -v -m 4 numba.tests.test_array_reductions.TestArrayReductions

Can you add information about how you installed Python and Numba too, please? Thank you!

25

Tests for cudf branch-0.19 and dask-cudf branch-0.19 are looking good with Numba 0.53.0RC3.

26

Bodo’s test suite (~6600 multi-part tests) and several large end-to-end applications pass with Numba 0.53.0RC3.

27

Great to hear this, thanks for testing @gmarkall @ehsantn !

28

Hi, @stuartarchibald!

Which version of NumPy are you using?

My NumPy version is 1.20.1

Where did you get the packages in the environment from?

Numba and NumPy got from pip.

I hope it will help you to investigate this matter.

29

Hello, @esc!

Can you add information about how you installed Python and Numba too, please?

Python was installed by official pkg-file from python.org, Numba - from pip.

Hope it will help.

30

Hi @AlexanderUp,

thank you for submitting this additional information. Did you use any environment management software, like pyvenv or virtualenv?

best,

31

@AlexanderUp thank you again for submitting this. I can reproduce this and have narrowed it down to Numpy 1.20.1 – I used Python from miniconda/conda and obtained Numpy 1.20.1 from conda-forge. I only obtained 8 failures, but they look very similar to the ones you posted.

Can you try to just downgrade Numpy to 1.19.2 and re-run the tests to see if helps? Thank you!

32

Hi @esc!

No, I don’t use neither pyenv nor virtualenv for numba tests.

Of course, will do it today later.

33

For the record, here is trace of the errors I received:

$ python3 -m numba.runtests -v -m 4 numba.tests.test_array_reductions.TestArrayReductions

I can report the same issue arises on Numpy 1.20.0

RE: Regressions for Numba 0.53.0rc* unit tests against NumPy 1.20.x. I think it’s due to this (quite possibly due to a NumPy bug fix)…

Reproducer:

import numpy as np

print(f"Version: {np.__version__}")

a = np.array([-np.inf, 1],)
q = np.array([0.0, 0.1,])

print(np.nanquantile(a, q))

With 1.19:

$ python numpy_bug.py 
Version: 1.19.2
[-inf -inf]

with 1.20

Version: 1.20.0
<path>/site-packages/numpy/lib/function_base.py:3963: RuntimeWarning: invalid value encountered in multiply
  lerp_interpolation = asanyarray(add(a, diff_b_a*t, out=out))
<path>/site-packages/numpy/lib/function_base.py:3963: RuntimeWarning: invalid value encountered in add
  lerp_interpolation = asanyarray(add(a, diff_b_a*t, out=out))
[nan nan]

Numba’s implementation matches NumPy 1.19.

Suspect this PR as the root cause of the change: https://github.com/numpy/numpy/pull/16273 and would guess at Update numpy/lib/function_base.py · numpy/numpy@2b7f671 · GitHub being the patch that changes the behaviour.

With regards to Numba 0.53.0RC3, I’m of the view that this is not a release blocking issue.

Hi, @esc!

Tried to test today (under pyvenv) with Numpy version 1.19.2, but another error occured. Anyway I treat this error as my system specific, and suggest do not take into mind.

$ python3 -m numba.tests.test_runtests --verbose

Best regards.

@AlexanderUp that looks like an error with Numpy, since it is crashing on NumPy import?
