[Numpy-discussion] Documentation Team meeting - Monday July 18 **NEW TIME** 2pm UTC

[Melissa Mendonça]

Hi all!

Our next Documentation Team meeting will happen on *Monday, July 18th*
at ***2PM
UTC***.

We are experimenting with this new time as a few contributors reached out
and mentioned that the original time didn't work for them.

*Please note that changes in the calendar may take a while to propagate.*

All are welcome - you don't need to already be a contributor to join. If
you have questions or are curious about what we're doing, we'll be happy to
meet you!

If you wish to join on Zoom, use this link:

Here's the permanent hackmd document with the meeting notes (still being
updated):

Hope to see you around!

[Numpy-discussion] Question about specifying structured dtype alignment

[Keith Morley]

Hello,

I have looked around for an answer to this, but havent found exactly what I
need.  I want to be able to create a structured dtype representing a C
struct with non-default alignment.  An example struct:

struct *__attribute__((aligned(8)))* float2
{
float x;
float y;
};


I can create dtype with two floats easily enough:

float2_dtype = np.dtype( [ ( 'x', 'f4' ), ( 'y', 'f4' ) ], align=True )


but the alignment for this dtype (float2_dtype.alignment) will be 4.  This
means that if I pack this dtype into another structured dtype I will get
alignment errors.  What I would really like to do is

float2_dtype.alignment = 8 # gives AttributeError: readonly attribute

or

float2_dtype = np.dtype( [ ( 'x', 'f4' ), ( 'y', 'f4' ) ], align=True,
*alignment=8* ) # Invalid keyword argument for dtype()


Is there a way to to this?  I apologize if I have missed an obvious
solution to this issue -- I have grepped around the internet and this
mailing list with no success.

Thanks
keith
