问题
I have added my python 3 executable to the system PATH (against the advice of Anaconda) to try and get Hydrogen (and really any Atom extension/plugin) to run lines or blocks of code in Atom. The 'scripts' atom plugin appears to work (I select some code and enter ctrl-shift-b), but I'd love to use more of the features in Hydrogen. When I execute (for example):
print('hello world')
I get the following error:
Python 3
Traceback (most recent call last):

ImportError: DLL load failed: The specified module could not be found.
I have reinstalled the package, I've tried using the Anaconda power shell and normal prompt to install and load Atom. My only guess is that its having trouble launching a kernel, or am I supposed to launch one and then connect?
End goal: run code block and it works.
回答1:
To use a Conda env as a kernel in Hydrogen you must register the env using ipykernel, e.g.,
conda activate myenv
python -m ipykernel install --user
This creates an entry for the kernel in a default user-level location that is generically visible to any Jupyter instances run by the user (such as Hydrogen). It is recommended to also include a --name NAME flag to distinguish your different envs. Please refer to the python -m ipykernel install -h for more options.
Also, note that the minimum requirement for using a Conda env as a kernel is to install ipykernel. And, yeah, clean up the PATH so that it conforms to Conda best practices - there should be no need for manually editing.
