Error upon attempting to start kernel (p.q:8) #38
Comments
|
Hi Michael,
It looks like jupyter lab is looking at the wrong version or path. Could
you provide us with more details about your installation?
- Windows or Linux install?
- If conda installation, could you provide the versions?
- $conda list "embedpy|jupyterq|kdb|python"
- Paths where they are installed (Linux / Windows):
- $ which q / $ where q
- $ which python3 / $ where python3
- $ which jupyter / $ where jupyter
Thanks,
Espe.

Hey, I did originally have the trial 32-bit version installed, but I thought I had removed all references (even the binary itself). Let me know if you see something off:

Everything seems fine there. Maybe the issue is with the jupyter-lab path.
Could you check that path too, please?
$ which jupyter-lab

This path seems okay too, but I just noticed our possible issue, in our particular setup, it's using python2.7 to run the Lab. Would we need to switch this to 3.6 for it to work? |

Yes, that's the problem. At the moment we don't support python 2.7 so it
won't work. I recommend you to install jupyter-lab in your environment
using 3.6 and it should work then. Anyway, you may find some issues when
using jupyter lab since some functionalities haven't been tested yet. You
can check this here (#12).

Could you double-check the python version that jupyter lab is running in a
console or notebook opened from JupyterLab instead of running python
directly from the terminal, please? This could be different and it may be
causing the issue. The error seems to be associated to jupyterlab only
since everything else works fine and p.q can be loaded from a q process.

I am working on this project as well, after this change it is working. looks like the system python was causing the issue, we will look into getting the python3 version in the correct path it needs thanks! |
