Connection issues with own metakernel
freifrauvonbleifrei opened this issue · comments
Hi,
I have recently ported my own Python-based Jupyter kernel to derive from metakernel instead of ipykernel.
Since then, I had the following issues:
- I get "forbidden" errors such as
[W 14:42:21.580 NotebookApp] Forbidden
[W 14:42:21.580 NotebookApp] 403 GET /api/config/common?_=1520862141398 (127.0.0.1) 1.43ms referer=http://localhost:8889/notebooks/ ...
which is possibly resolved by using the --NotebookApp.token=''
flag
- The %connect_info magic gives this info:
{
"stdin_port": UNKNOWN,
"shell_port": UNKNOWN,
"iopub_port": UNKNOWN,
"hb_port": UNKNOWN,
"ip": "UNKNOWN",
"key": "UNKNOWN",
"signature_scheme": "UNKNOWN",
"transport": "UNKNOWN"
}
which should be more sensible, comparing to the metakernel echo example.
- when playing around with matplotlib, I got errors saying that there are no
comm
and interactive shell instances - but then I am not sure if there should be.
Any ideas on what is happening here?
I think that I have adapted the necessary lines from the examples to my kernel.
Do you have recommendations on how to debug these errors?
Looking into this...
