numpy array conversion to q

t[12]~np[:arange][*][12.]
t[12]~np[:arange;*][12.]
t[12]~np[:arange][*;12.]
t[12]~np[:arange;*;12.]
t[12]~np[:arange][12.]
t[12]~np[:arange;12.]

used the test cases. the symbol is not shown in this post above t[12]~np[:arange][*][12.] get 0b

Hi,

Could you please provide the code for what t is?

If t[12] is equivalent to the q function q)til 12 then the following should rectify the problem:

q)t:{til x}

q)t[12]~(np[:arange;*][12])
1b

Thanks,
Diane

[ghlian]

the codes are simply the testcases in embedPy/tests/syntax.t

All return 0b.
q)t[12] is working fine.

[ghlian]

however, in numpy 1.14.3 and q version 3.5 64bit, all the testcases return 1b.

Hi,
I think there are were some issues with backticks "`" disappearing in the markdown.

I haven't been able to replicate this so far using the latest version of embedPy and kdb+ 3.6 on any of linux, macOS or windows.

Can you let us a few more details so we can try and replicate your issue.

• Which OS?
• Are you installing embedPy with the conda package?
• If not using conda, was embedPy installed from a release from the releases page or cloned and built from source?
• If you installed with a release, which version of embedPy was used?

Below is what I get by building from the latest version of the source (on linux in this case)

$ conda list numpy && conda list python
