kandi X-RAY | nb_conda_kernels Summary
This extension enables a Jupyter Notebook or JupyterLab application in one conda environment to access kernels for Python, R, and other languages found in other environments. When a kernel from an external environment is selected, the kernel conda environment is automatically activated before the kernel is launched. This allows you to utilize different versions of Python, R, and other languages from a single Jupyter installation. The package works by defining a custom KernelSpecManager that scans the current set of conda environments for kernel specifications. It dynamically modifies each KernelSpec so that it can be properly run from the notebook environment. When you create a new notebook, these modified kernels will be made available in the selection list.

QUESTION
When JupyterLab tries to start, in some occasions, the config file may be invalid, and Jupyterlab starts regardless in default port 8888
.
Currently I have a JupyterLab service defined as follows, but I also try to start it manually and got the same results. An example when config file may be invalid is when a library is not available to be imported. I want to prevent Jupyter to start and fail gracefully.

(see docs); on Linux this can be done by prepending the startup command like so:

I'm new to Docker. The image I am using is kaggle/python https://github.com/Kaggle/docker-python/blob/main/Dockerfile
Using this image, I would like to create a new image which:
(1) Has some more packages
(2) Prevents Jupyter from starting up automatically each time the container is run (the source image does this - I can't seem to find the command in the docker file where this is invoked)
Edit: I have found the line where Jupyter is invoked, however I am unsure as to how it can get ignored in my new image

QUESTION
All of my virtual environments work fine, except for one in which the jupyter notebook won't connect for kernel. This environment has Zipline in it, so I expect there is some dependency that is a problem there, even though I installed all packages with Conda.
I've read the question and answers here, and unfortunately downgrading tornado to 5.1.1 didn't work nor do I get ValueErrors. I am, however, getting an AssertionError that appears related to the Class NSProcessInfo.
I'm on an M1 Mac. Log from terminal showing the error below, and my environment file is below that. Can someone help me get this kernel working? Thank you!

I'm trying to automatically start jupyter server on boot. (ec2, amazon linux)
I got the jupyter server working and correctly loading all the conda kernels.
and I tried to run jupyter on boot. (tried rc.local, systemd, crontab and all fails to load conda kernels and only loads basic python2 and python3 kernels)
I've traced it down to the nb_conda_kernels not finding being able to call 'conda' on boot, as below:

I installed snorkel using conda and when I try to run - from snorkel.labeling import labeling_function
it throws the following error - ModuleNotFoundError: No module named 'snorkel.labeling'
.
I tried looking up for a solution on Github, but unfortunately, I couldn't follow through. I have also tried installing nb_conda_kernels
, to make all your conda environments available in jupyterbut it didn't help. Also tried creating a separate env, installing snorkel and launching jupyter notebook from the snorkel's environment, and it didn't work either. Any form of help is much appreciated!
Thanks in advance!
