Hello,

Currently using trial kdb version, it’s working well.

KDB+ 4.1 2024.10.16 Copyright (C) 1993-2024 Kx Systems
l64/ 4(24)core 7461MB rr local 127.0.1.1 EXPIRE 2025.12.14 @gmail.com KDB PLUS TRIAL #xxxx365

Tried installing PyKX and it’s dependencies.

Linux local 6.8.0-50-generic #51~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Nov 21 12:03:03 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

Python 3.10.12 (main, Nov 6 2024, 20:22:13) [GCC 11.4.0] on linuxType "help", "copyright", "credits" or "license" for more information.

When I have tried for first time, that is, importing pykx, it worked.

import pykx as kx

kx.license.install('/home/rr/q/l64/kc.lic')
PyKX license successfully installed!

However after installing kdb+ license, started throwing the below error. How to fix this issue? appreciate your help! Thanks

kx.q.til(5)
