2 minutes to start a jupyterq kernel

[kimtang]

Hi all,

when starting the jupyterq kernel we can see that the jupyterq_server.q q process is trying to make a connection to the 'outside'. See the strace below. Our servers are all secured and do not allow any connection to the outside.
However this side effect will timeout in 2 minutes making the q kernel unresponsive. Is it possible to turn this off?

Thanks,
Kim

(base) $strace -p 4928
Process 4928 attached

Hi Kim,

Just to clarify, when you say connect to the ‘outside’ do you mean trying to connect to the internet? When initializing jupyterq, it attempts to access https://code.kx.com/ to display documentation for built-in functions while running the notebooks which could cause that issue if internet connection is not available.

Hi Diane,

Yes, there is no internet connection available. Is there a flag to turn it off?

We are currently working on a fix for this that will hopefully be included within a future release. In the meantime, you can use the following workaround as a temporary fix:

In the script jupyterq_help.q found in your QHOME - amend line 30

refcard:@[req:{"c"$.p.import[urllib.request][:urlopen][x][:read][]};(hb:"https://code.kx.com/v2/"),"ref";{0}];

to

refcard:0;

This is good. Let me try it and will confirm back if it is working.
Thanks for your quick reply.

Yes, this is working.
