Brutus cannot be imported in both python2 and python3

[xnaxe29]

Dear Developer,

I cannot run brutus in either of my python versions - 2.7 and 3.7. here are the related errors -

Python3 -

import brutus

PS: I must say that I have installed pyqz using pip install pyqz without any issues, but it cannot be imported. Not sure what can be done here.

Python2.7

Hi @xnaxe29,

Thanks for the interest in brutus. The bug you are seeing is linked to the underlying pyqz module (see fpavogt/pyqz#4).

Unfortunately, both pyqz and brutus are deprecated, and I do not expect to revive either of them. Instead, I would suggest that you look at brutifus and nebulabayes. The first one is the successor to brutus, and the second one superseded pyqz.

If you decide to try brutifus and encounter any trouble with it, please submit a new issue over there. I've been handing over responsibility of the code, so knowing that there are other people interested in this might help keep it operational.

(P.S.: I realize that the brutus doc is not very explicit regarding the deprecation of the code. I'll fix that in the coming days.)
