Error: No module named arma

[cdeil]

A colleague of mine asked me to install spectrum.

I get a few errors with Python 3 and an ImportError for arma (that is also there for Python 2).

Hi,
This may not be relevant anymore but looking at this issue 6 months later, I cannot reproduce this bug under Python 3.4.1 with the current version of spectrum (0.6.1) using either the source code or the version posted on pypi.

Same issue with Raspberry pi + python 3.5. Works fine under Windows.

[JanCBrammer]

@ergindemir, @cokelaer, same issue here (Python 3.5 on Raspbian and spectrum 0.9 as well as 0.7.5). Did you find a solution?

[PokerMakyo]

I'm also experiencing this issue on Raspbian GNU/Linux 10 (buster).

[adessein]

I have tried again with the master version from this git repository (0.7.5), as well as from pip (0.7.5) and I have no problem since in __init__.py
import arma
has been changed for
from .arma import *
tested both with Python 2.7.16 and Python 3.7.3 on Debian (4.19.0-6-amd64).
How can that be a problem related to Raspbian ?

[EvanKat]

The same problem with spectrum using python 3.11.2 at a raspberry pi4 model b (version 12 bookworm).
Using pip install spectrum at 31/10/23, the spectrum module installed is 0.9 .
While looking around to the files and comparing it to the github's version 0.8.1 witch is saying is the latest (?) I detect some differences that didn't make sense (i suppose so).
After all using the commands
pip install git+https://github.com/cokelaer/spectrum.git
or
pip install spectrum==0.8.1
the problem gone and no dependencies errors.
