numpy array returns as foreign

[estradajke]

Hi. I am unable to return a numpy array as anything but foreign. Am I missing some syntax to force the conversion? I've downloaded the latest embedPy files and running a recent version of kdb and python.

Just noticed the formatting was unclear.

Hi,

It looks to be an issue with either the use of Python 3.10 or an update to numpy.

Can you provide the version of numpy that you're using please and we'll aim to take a look.

Thanks for the quick reply Conor. It's 1.22.1. I'm happy to move to another recent version if that helps.

q)np:.p.import[numpy];np[:version]`
"1.22.1"

I've confirmed it's the numpy version that is the issue, it looks like the underlying representation at the C level has changed somewhat which we'll need to investigate. If you downgrade numpy to <1.22 the behaviour should resolve itself, at the present time there isn't an explicit workaround

Rolled back to 1.21.

q)arange[12]`
0 1 2 3 4 5 6 7 8 9 10 11

Thanks!
