- - conda create -q -n thinkstats2-py27 python=2.7 scipy numpy matplotlib statsmodels patsy future jupyter
- - conda create -q -n thinkstats2-py36 python=3.6 scipy numpy matplotlib statsmodels patsy future jupyter

+ - conda create -q -n thinkstats2-py36 python=3.6 scipy numpy matplotlib statsmodels patsy future jupyter seaborn
 
 Each of these commands will take a bit of time -- give it a few minutes
 to download and install the packages and their dependences. Once complete,
 switch to each and install additional packages needed to run and test.
