Error installing cvxopt using Conda

I'm attempting to install cvxopt using Conda (which comes with the Anaconda python distribution), and I received the error message below. Apparently my Anaconda installation is using python 3.6, whereas cvxopt wants python 3.5*. How can I fix this and install cvxopt using Conda?

After typing conda install cvxopt at the Anaconda prompt, the message I received was:

Fetching package metadata ...........

Solving package specifications: .

UnsatisfiableError: The following specifications were found to be in conflict:

- cvxopt -> python 3.5*
- python 3.6*

Use "conda info < package >" to see the dependencies for each package.

Here's a screenshot of the error message: enter image description here

It would appear that cvxopt requires Python 3.5. Easiest solution would be to use conda to create a separate environment for python 3.5 and then install cvxopt (and any other desired python packages). For example...

conda create -n cvxopt-env python=3.5 cvxopt numpy scipy matplotlib jupyter

...depending on your operating system you can then activate this environment using either...

source activate cvxopt-env

...or...

activate cvxopt-env

...you can then switch back to your default python install using...

deactivate

...check out the conda docs for more details. In particular the docs for the conda create command.
