Help us testing 0.52.0 RC

Announcements
1

We are inviting the boarder community and downstream projects to help us test Numba 0.52.0 and llvmlite 0.35.0 release candidates.

We would appreciate downstream projects to test our release candidates in their respective CI infrastructure and report regressions to our issue tracker.

We are also experimenting with the idea of getting sign-offs from the following opensource projects that have, in previous releases, reported regression issues:

  • Awkward
  • UMAP
  • librosa
  • RAPIDS
  • SDC
  • pydata sparse
  • clifford

Please comment in this thread if you can help with testing our packages and mention the project that you are associated with (if you can).

We are currently at RC2. Conda packages are in the numba channel. Wheels are available on PyPI.

Thanks in advance for everyone helping us test Numba.

I ran the Awkward Array integration tests, which includes all of our tests of Numba’s extension mechanism (extending it to recognize and correctly navigate Awkward Arrays). There were no errors.

hi!

I tested 0.52.0rc2 at work and it passed CI. No changes in performance

Update: it turns out that mamba is using numba 0.51.2 instead of numba 0.52.0rc2. So we haven’t really tested 0.52.0rc2 yet.

Update2: after switching to conda for the environment creation, numba 0.52 is correctly installed. The execution time was reduced by 10%.

Hi! (@esc brought me here)

I ran the poliastro test suite with numba 0.52.0rc2 and all tests passed without errors. I unfortunately don’t have the capacity to run proper time benchmarks today, but from a couple of quick runs with both versions I don’t see much difference in performance.

Hi Siu

I’ve tested RBC with Numba 0.52 RC2 and there were no errors

>>> import numba
nu>>> numba.__version__

The clifford azure CI run against numba master appears to be passing still

Many thanks to all those who have replied so far, this is very encouraging.

8

0.52 RC2 seems to work fine with PyData/Sparse as well on macOS. Thanks for the awesome work!

9

I didn’t run any test suite, but I’ve used it casually for a bit and haven’t observed any issues

10

RC3 is now available.

conda-packages: numba and llvmlite
wheels and source tarballs: numba and llvmlite

Please see the RC3 milestone for a list of changes: https://github.com/numba/numba/milestone/49?closed=1. The changes in RC3 are minor or opaque to user-facing API—adjustment of optimization passes, changes of internal C code.

11

I’ve tested locally with the RAPIDS libraries branch-0.17 (cuDF, cuSpatial, cuML, cuGraph) with single- and multi-GPU with 0.52.0RC3 and not encountered any issues.

12

I re-ran my tests with RC3 and it passed CI (and kept the 10% performance improvements from RC2).

13

Thank you everyone for testing. You have helped us make sure that the final release is smooth and stable.
