Issues running the kernel

[jdenver13]

After installing on my Mac, I cant get the hass-pyscript-jupyter to work
Running 'jupyter kernelspec list':

[ListKernelSpecs] WARNING | Native kernel (python3) is not available
[ListKernelSpecs] WARNING | Native kernel (python3) is not available
Available kernels:
  pyscript    /usr/local/share/jupyter/kernels/pyscript

Running 'jupyter pyscript info':

hass_pyscript_kernel version 1.0.0 installed
Kernel pyscript installed in /usr/local/share/jupyter/kernels/pyscript
Config settings from /usr/local/share/jupyter/kernels/pyscript/pyscript.conf:
    hass_host = 192.168.1.63
    hass_url = http://192.168.1.63:8123
    hass_token = 6MTYxNzE5MDI1OSwiZXhwIjoxOTMyNTUwyoPnHd8vvF0upJAKRCzsek
    hass_proxy = None

If I run 'juptyer notebook', all seems ok:

     or http://127.0.0.1:8888/?token=8c639d693d8f0

If I then select 'hass pyscript' in Jupyter notebooks 'New' menu I get:

Any ideas where to go from here or what to try please.

Came across the same problem. The kernelspec refers to python as the python binary to use, but it's not using the one which the shell points to when in a virtualenv. Not sure if this is a problem with jupyter or with this tool.

This can be 'fixed' by setting the binary to the one which has access to the hass_pyscript_kernel module.

1. Run jupyter kernelspec list
2. Open the file kernel.json in the folder which is listed next to pyscript in the previous command's output
3. Change python in argv to whatever comes out of which python when running that in your virtualenv

On to the next problem, connection refused... 😞

Any update on this? I also have this problem. HTTP 400, 401 and 403s
