conda and python default kernel

[testb...@gmail.com]

Hi,

Could anyone provide some details on the below?

I have anaconda2 and anaconda3 installed. In Jupyter Notebook, I see conda and python [default] kernel.

1. What is this conda kernel? When this would be useful?

2. How to remove the conda kernel if I don't need it and add it back later?

3. I see the python [default] kernel. This is confusing as I will be using only the anaconda2 and anaconda3 python kernels.

3.1 When this default kernel will be used or will be useful?

3.2 Can I remove this kernel if I don't need it?

3.3 If I remove now, can I add it back later?

Thanks in advance!

You shouldn't need to. You can use Python2 and Python3 at the same
time regardless of the anaconda you install.

Conda notebook ships with custom extension that will auto-discover
kernels based on available conda environments. It won't
autodiscover across anaconda install AFAICT.

You might have to uninstall nb_conda_kernels IIRC, just reinstall it
to get things back.

- IIRC that's the same Python than the one the notebook is started
with. That's needed to be sure we have at least one kernel available.

- Yes (see above)

- Yes. See above, or install the kernelspec by hand.


I'm just confused by the having both anaconda 2 and 3 both installed.
