MY INTRODUCTION TO NumPy COMMUNITY
by Nkep Kerlyn March 13, 2019

March 13, 2019

Hello everyone, I am a Computer Engineer(Telecoms major) from Buea, Cameroon. I recently completed undergraduate studies from the University of Buea. I am interested in contributing to NumPy during and after the upcoming session of Outreachy 2019. I am proficient in Python and fluent in English speaking and communication. I am also a beginner in NumPy but I am ever ready to learn. I have looked at the Outreachy Ideas page. I have setup my development environment and will start solving issues immediately. I will be grateful if i can be pointed out to a good first bug. I look forward to interacting with you all and contributing to this awesome community. Regards, Kerlyn Nkep.

No idea yet. I suspect that either the PSF or NumFOCUS (or both) will though.

NEP-18 comment
by Frederic Bastien March 7, 2019

March 7, 2019

Hi, I was told recently about the NEP-18. I like it, but I have a comment. At first, it is enabled in a release by setting an environment variable. Then in the following release, it is enabled by default. Is it possible to allow for the second release to disable it by an environment variable? This would allow to disable it for people that would be inconvenienced by this change. Who could be negatively impacted by this? Small array operation. I recall many years ago of much effort to speed up small array, including at least one GSoC. I didn't do timing, but I'm pretty sure the change needed for NEP-19 raise the default overhead for all operation that it impact. I also recall people in the mailing list asking how to speed up the small array case. So giving people a way to not pay for that overhead would make sure that for people that care about the small array cases won't pay that extra overhead price. So they won't see a slowdown by updating NumPy. Probably less than 1% of user will enable the new functionality in the current release as it is not enabled by default. Making it easy to try is great, but doesn't guaranty that it will be tested in all corner cases. So it isn't sure we would heard before the second release about regression this change does. What do you think about that small changes? Thanks for the great work on such important library.

hello just a notice to help preventing future problems... python-3.8.0 (alpha) emits the following warning on numpy/ma/core.py (verified up to official 1.16.2): ----8<---- /usr/python3/site_python3/lib64/numpy.egg/numpy/ma/core.py:4466: SyntaxWarning: "is" with a literal.
