We can make this file beautiful and searchable if this error is corrected: It looks like row 9 should actually have 11 columns, instead of 8 in line 8.

installing and running jupyter notebooks on miniconda

I had some trouble running jupyter notebooks with miniconda from a new env. The key is miniconda doesn't install a fresh python install for each new env. This leads to unable to create process /blah/Miniconda3/python.exe from /blah/Miniconda/envs/myenv/Scripts/jupyter-notebook.py

So install another version of python (can be same release) into your env, install jupyter, and run jupyter notebook. Copy the token and paste it into the url bar.

Then follow directions http://jupyter-notebook.readthedocs.io/en/latest/public_server.html and setup your password using jupyter_notebook_config.json

Then you can run, and log into your notebook session securely from there on out.
