Hi, I use Spyder myself, so I am not sure how the atom or Sublime Text Editor works.
How did you install pydna the first time? and which version?
I assume you are on linux?
Import pydna
pydna.__version__
Are you using the system python installation or some environment like conda or virtualenv ?
The fact that you have an installation on your machine but atom seem not to be able to find it
suggests that some environment variable somewhere is wrong?
