I also changed 'jupyter_config.json' file.

{
"JupyterApp": {
"kernel_spec_manager_class": "nb_conda_kernels.CondaKernelSpecManager"
},
"CondaKernelSpecManager": {
"kernelspec_path": "--user"
}

}

These are the versions I have.

And I created 'jupyter_notebook_config.py' and added the sentence below.

c.EnvironmentKernelSpecManager.conda_env_dirs=['C:\Users\Yusuke\AppData\Roaming\jupyter\kernels\python3']

I wrote

python -m ipykernel install --user

but it did not work for me.

This took me two weeks! Thank you!

Hmm. I just noticed something that I didn't dawn on me at the time in https://github.com/jupyter/notebook/issues/4079 and that is that EnvironmentKernelSpecManager is from a different project - similar to nb_conda_kernels. It clearly looks like you're using nb_conda_kernels but I wonder if there's a mixture of settings between these two "custom" kernel spec managers.

Also, you should probably stick with a single source for your configuration and try to eliminate this message:

as this may be leading to some confusion as well.

Thank you, kevin-bates. Is this what you mentioned before? I changed the file name of "jupyter_notebook_config.py".

There are a few odd things going on. It appears you have a mixture of Lab >= 3 (which uses jupyter_server) vs notebook. I'm curious what is produced if you run jupyter lab --debug. (also, it would be good to add --debug in general when troubleshooting).

I'm hoping someone here knows what's going on with the nb_conda handlers in the traceback. Looks like some executable is not available.

And, yes, it appears as though the mention of EnvironmentKernelSpecManager has been eliminated, so that's a good simplification to resolving this.

Is this what you metioned?

Are there other options listed in the dropdown list? This is showing the kernel option associated with your base conda environment. Is that the conda environment in which you want your kernel to run?

In the Jupyter Lab launcher, you should see a tile for all of your conda envs, plus tiles corresponding to other configured kernels: image

@yuskeaita the feature you want to use is related to this package. If you want to manage your conda environments. I suggest you give a try to gator. :warning: it has integration with the classical notebook up to v4. Starting from v5, you could still manage your conda environments but either from JupyterLab or from a standalone tool.

Indeed, this looks like an issue with nb_conda and not nb_conda_kernels. I agree with @fcollonval 's suggestion about gator, which is a great package.
