Hi, 

I am new to pykx.

What license do I need to install pykx . At the moment I only have q license 


Error:

shutil.SameFileError: '/home/xxx/q/kc.lic' and '/home/xxx/q/kc.lic' are the same file

2

PyKX and q/kdb+ use the same license. 


1. What command is giving you that error?

It suggests you are trying to install the license a second time.

2. What output do you see when you 'import pykx' in your python session?

1>>> import pykx as kx

You appear to be using a non kdb Insights license.
Captured output from initialization attempt:

License location used:

Running PyKX in the absence of a kdb Insights license has reduced functionality.

Your license does not have a needed flag to enable PyKX.


Go to: https://kx.com/kdb-insights-sdk-personal-edition-download/

Download  this new license and install it and this new license will work for kdb+ and PyKX for you.

thank you.


I downloaded a new lic but it is only valid for 4 days.


>>> import pykx as kx
WARNING:root:PyKX license set to expire in 4 days, please consider installing an updated license


Are all licenses only valid for 4 days now ?

6

What is the output of: kx.q.take(4,kx.q.z.l) ? Normally it should be issued with a longer duration. 

7

hi this is the output

>>> kx.q.take(4,kx.q.z.l)
pykx.List(pykx.q('
"24"
"2025.03.17"
"2025.03.17"
,"1"
'))

I checked and if you previously registered for that type of licence and you request a new one before the previous is expired you will be sent the original license. When this one expires you can request a new one on the 18th which will be valid for a further 90 days.

I requested a new lic but here is the message:

Your download request could not be completed.
We are sorry but at this time we cannot grant you access to the kdb Insights SDK Personal Edition. Please contact sales@kx.com for further assistance.
