one possibility for getting the notebook filepath is finding and parsing /home/sagemaker-user/.jupyter/lab/workspaces/default-37a8.jupyterlab-workspace I think, but I don't know if I can tie that to a specific session

@<1532532498972545024:profile|LittleReindeer37> nice!!! 😍
Do you want to PR? it will be relatively easy to merge and test, and I think that they might even push it to the next version (or worst case quick RC)

At the top there should be the URL of the notebook (I think)

the problem is here: None

so notebook path is empty

Try to add here:
None

server_info['url'] = f"http://{server_info['hostname']}:{server_info['port']}/"

I've poked around both the internal URL that Jupyter kernel is running on and some of the files in /sagemaker/.jupyter but no luck so far - I can find plenty of kernel info, but not session

and the only calls to "uri": "/api/sessions" are the ones I made during testing - sagemaker doesn't seem to ever call that itself

yeah, even then it'll run but return 0 notebooks

and cat /var/log/studio/kernel_gateway.log | grep ipynb comes up empty

as best I can tell it'll only have one .ipynb in $HOME with this setup, which may work...

if I change it to 0.0.0.0 it works

but the only exception handler is for requests.exceptions.SSLError

poking around a little bit, and clearml.backend_interface.task.repo.scriptinfo.ScriptInfo._get_jupyter_notebook_filename() returns None

nice! Just tested it on my end as well, looks like it works!

nope, that's wrong

Nice

lots of things like {"__timestamp__": "2023-02-23T23:49:23.285946Z", "__schema__": "sagemaker.kg.request.schema", "__schema_version__": 1, "__metadata_version__": 1, "account_id": "", "duration": 0.0007679462432861328, "method": "GET", "uri": "/api/kernels/6ba227af-ff2c-4b20-89ac-86dcac95e2b2", "status": 200}

which I looked at previously to see if I could import sagemaker.kg or kernelgateway or something, but no luck

at least in 2018 it returned sessions! None

Hmm what do you have here?

os.system("cat /var/log/studio/kernel_gateway.log")

but even then the sessions endpoint is still empty

it does return kernels, just not sessions

This is very odd ... let me check something

right now I can't figure out how to get the session in order to get the notebook path

you mean the code that fires "HTTPConnectionPool" ?

Hmm and you are getting empty list for thi one:

server_info['url'] = f"http://{server_info['hostname']}:{server_info['port']}/"

api/kernels does report back the active kernel, but doesn't give notebook paths or anything
