jupyter kernelspec list does not show the tslab kernel

[danvln]

Is anything that's broken in this solution, I installed it but I do not see the kernel running. Anything special that I should do to get it running? There is no error, or issue that I see. How do I investigate it?

Any input on this?

Could you share your information about your environment and what command you run?

Internally, tslab install invokes python/install.py with python3 (python in Windows) internally (source).

One possible reason of the problem is the Python tslab used to install the kernel is different from the Python used from your jupyter command (e.g. python3 and python2 are mixed). In Unix-like system, the kernel configs are usually installed under $HOME/.local/share/jupyter/kernels/tslab.

Hi we684123,

You have to run tslab install after npm install -g tslab. https://github.com/yunabe/tslab#installing-tslab-1
