Hydrogen just gives me this error message when trying to run python code:

No kernel for grammar Python found

Check that the language for this file is set in Atom, that you have a Jupyter kernel installed for it, and that you have configured the language mapping in Hydrogen preferences.

To detect your current Python install you will need to run:

python -m pip install ipykernel
python -m ipykernel install --user

I have a Jupyter Kernel installed. It is not clear, why this does not work, while when started form the console it just works.

Also it is totally not clear what a user should do to solve that situation. It is not clear where or how to execute python -m pip install ipykernel . Also the install instructions on https://nteract.io/kernels do not cover how to install a kernel to Hydrogen.

The startup experience is very, very disappointing. I am searching for simple tools that I could use to teach a little bit Python and both, nteract and hydrogen can not be used with python beginners because they will hit a big frustrating wall with nothing working. I want to avoid first having them to teach how to use the "scary terminal" to get a JupyterLab running, but nteract and hydrogen, not working out of the box, make it even more complicated.

Please try yourself to install and run nteract and / or hydrogen and see how it just does not work and produces the typical beginner frustration wall, leaving the user with a situation that he will be not able to solve. Please provide software that just works so it can be used with unexperienced users and does not force teachers to spend a lot of time to debug scholar workstations.

I understand your experience. When I first tried to install hydrogen, it left me so extremely frustrated and upset and messed up my whole day. It took me 3 days to get hydrogen installed. The biggest thing is that hydrogen is a tool for jupyter kernels, but we do not force you to use a certain kernel and because of this, if you don't understand kernels and how they work or how Atom's paths work, it is extremely difficult for beginners to figure out what to do and where they went wrong. As far as installing goes, those commands are meant to be run in your terminal.

It'd be nice if hydrogen detected the kernels generated automatically by nb_conda_kernels
