Stuck in "kernel status: initializing" with ipykernel

giuli9 · October 18, 2024, 11:03am

When I run the Jupyter Notebook I receive this error

    Traceback (most recent call last):
      File "/Users/sauron/opt/anaconda3/lib/python3.9/site-packages/tornado/web.py", line 1790, in _execute
        result = await result
      File "/Users/sauron/opt/anaconda3/lib/python3.9/site-packages/aext_assistant_server/handlers.py", line 117, in get
        raise HTTPError(403, reason="missing nucleus_token")
    tornado.web.HTTPError: HTTP 403: missing nucleus_token

When I try to connect to a kernel, this is what happens:

I have MacOS BigSur 11.7.10

Any suggestions would be appreciated

Edit your ‘/Users/sauron/opt/anaconda3/lib/python3.9/site-packages/aext_assistant_server/handlers.py’
and in the class ‘NucleusTokenRouteHandler’, change it to be:

class NucleusTokenRouteHandler(APIHandler):
    @tornado.web.authenticated
    async def get(self):
        api_key = _load_api_key()

        #if not api_key:
        #    raise HTTPError(403, reason="missing nucleus_token")

        #expires_at = get_expires_at(api_key)
        expires_at = 0
        self.finish(
            {
                "access_token": api_key,
                "expires_at": expires_at,
            }
        )

comment those lines and adding line ‘expires_at = 0’, that’s all!
