Having trouble importing REBOUND in Jupyter Notebook

[Dean Sayre]

I usually use Atom as a text editor when coding, but I need to use the notebook to make use of its widget capabilities. First off, running a notebook in my home directory, I'm able to import Rebound but for some reason it doesn't recognize one of the functions I jot down. I'm certain that I have it typed in correctly, I've attached the screenshot.

Then I try running rebound outside of my home directory, and it doesn't even recognize at all, leaving me unable to import it.

I find this odd since I'm not having these problems in Atom.

I'm running Jupyter Notebook 5.0.0. If you'd like to know more about rebound, here is the link: http://rebound.readthedocs.io/en/latest/index.html

Further, I've checked to make sure that the attribute 'Simulation' was in the rebound module and it was. This leads me to believe that the error involves Jupyter and Rebound not communicating.

You may have a file called rebound.py in your home directory which you're importing instead of the real rebound package.

If you can't import it at all, that probably means that Jupyter is running on another Python installation or environment from the one on which you installed rebound. Packages have to be installed in each Python environment you want to use them from. Check sys.executable to see which Python you're running, and sys.path to see where it imports from.

The executable spits out: /Users/Dean/anaconda3/bin/python

and the path: ['', '/Users/Dean/anaconda3/lib/python36.zip', '/Users/Dean/anaconda3/lib/python3.6', '/Users/Dean/anaconda3/lib/python3.6/lib-dynload', '/Users/Dean/anaconda3/lib/python3.6/site-packages', '/Users/Dean/anaconda3/lib/python3.6/site-packages/Sphinx-1.5.6-py3.6.egg', '/Users/Dean/anaconda3/lib/python3.6/site-packages/aeosa', '/Users/Dean/anaconda3/lib/python3.6/site-packages/setuptools-27.2.0-py3.6.egg', '/Users/Dean/anaconda3/lib/python3.6/site-packages/IPython/extensions', '/Users/Dean/.ipython']

I'm a bit of a mediocre programmer here, so I don't really know how to analyze the two.

I ran sys.path in Atom and got: ['/Users/Dean', '/Users/anaconda/lib/python35.zip', '/Users/anaconda/lib/python3.5', '/Users/anaconda/lib/python3.5/plat-darwin', '/Users/anaconda/lib/python3.5/lib-dynload', '/Users/anaconda/lib/python3.5/site-packages', '/Users/anaconda/lib/python3.5/site-packages/Sphinx-1.4.1-py3.5.egg', '/Users/anaconda/lib/python3.5/site-packages/aeosa', '/Users/anaconda/lib/python3.5/site-packages/setuptools-23.0.0-py3.5.egg']

The difference is in the python/package versions. My terminal is also running this same path.

[Thomas Kluyver]

It looks like you have two Anaconda installations; Jupyter is running in one, and Atom (and your terminal) in another.
