Error when running first example

[realSAH]

I followed installation instructions but have failed to run the first example.
I'm glad to contribute with a slick script that install all the requirements with one command when I can successfully run it.

Can you tell me what it is about?

Can you tell me what it is about?

[realSAH]

I ran python inside repo directory and it worked.
