Cannot run misle example

Hi. I have successfully installed the misle package using your instructions, but trying to run the example code produces the following output (with trace). The virtualenv is running Python3.6 on ubuntu 18.04.

Is there possibly something wrong with the shape call on line 11?

Thanks, Brandon
