[Numpy-discussion] GSOD-NumPy 2023: Review at next Community Meeting

[Mars Lee]

Hi all! 
I'll be hosting Review #3 for the 'NumPy Contributor Comics'. It will be hosted 
at the next NumPy Community Meeting on Dec 6. It will take about 15 minutes. 
You can also comment on Github: https://github.com/numpy/numpy/issues/25318. 

The review will be open for the next two weeks and close on Dec 20.

I also gave a talk about this project at the PyData NYC conference. Here's a 
link to the video: https://youtu.be/Gv_Ea94wquM?si=drLkjdN_0A75Jshn&t=40

See you there!
- Mars

Great, thanks for confirming!

[Numpy-discussion] Re: complex_ imported by numexpr, but seems no longer supported by numpy

[腾刘]

Ah, sorry I don't know why I searched in the documentation but it didn't
come out or something went wrong to my eyes , anyways I searched in doc now
and it's right there.

The reason numexpr.test() fails is because I'm using numpy 2.0.0.dev where
complex_ has been removed.

So problem solved, I should change the behavior of numexpr.test().
