python 3 7 anaconda

1conda install python=3.7 anaconda=custom

1As suggested here, with an installation of the last anaconda you can create an environment just like Cleb explained or downgrade python :
2
3conda install python=3.6.0
4With this second solution, you may encounter some incompatibility issues with other packages. I tested it myself and did not encounter any issue but I guess it depends on the packages you installed.

6If you don't want to handle environments or face incompatibilities issues, you can download any Anaconda version here: https://repo.continuum.io/archive/. For example, Anaconda3-5.1.0-XXX or Anaconda3-5.2.0-XXX provides python 3.6 (the suffix XXX depends on your OS).
