Unit test failure

[3rw4n0]

Hello,

Sorry to bother you with my issue, but I don't think I've seen anyone else report the same problem as mine.
I'm still very much a neophyte when it comes to python and, by extension, anaconda.
So, I hope that perhaps my problem is actually trivial.

I seem to have succeeded in installing PhySO because when I list the modules installed for python in the Anaconda prompt, physo appears in the list.
I was also able to install all the requirements.

However, when I run the unit test, I get a failure.

Also, despite installing MiKTeX and the necessary packages, I get question marks instead of mathematical symbols in the Anaconda Prompt.

My results are below.
I'd be very grateful if you could help me understand what's wrong.

Kind regards.
