Question

When I run Python from the terminal and from Atom, different versions of python are called. As a consequence, there are packages that I can call without problems fr

Ok, I had actually to change the Path in the .json file of the jupyter kernel. First I checked the list of jupyter kernel:

$ jupyter kernelspec list
julia-0.6    /Users/mymac/Library/Jupyter/kernels/julia-0.6
julia-1.0    /Users/mymac/Library/Jupyter/kernels/julia-1.0
python3      /Users/mymac/Library/Jupyter/kernels/python3

I then cd the above python path and, I found the file kernel.json inside and opened it:

{
 "argv": [
  "/path/to/python",
  "-m",
  "ipykernel_launcher",
  "-f",
  "{connection_file}"
 ],
 "display_name": "Python 3",
 "language": "python"
}

In that file, I then changed the line /path/to/python by the python path I got when typing the following in Terminal:

$ which python
/Users/mymac/anaconda3/bin/python

Relaunched Atom and it finally worked!

The hints of the github page of jupyter helped also a lot!
