the plot function does not work properly

I am following the documentation on beat.editor (https://www.idiap.ch/software/beat/docs/beat/docs/master/beat.editor/doc/user.html). I have a working conda environment with all the necessary packages and python 3.6 installed. I could run the experiment in the tutorial but when I wanted to plot the results I got the following error. Any idea what might be the problem? Thanks.

beat exp plot --show test/test/iris/1/iris
