Opening ipython and importing the installed version 0.9 of spectrum return errors.

Errors

[verbatim begin]

[verbatim end]

Roundabout way

To install without errors the version must be specified:

[verbatim begin]

pip install spectrum==0.8.1

[verbatim end]

dear @roitnedurp

thanks for reporting this issue. I am quite surprised since I have not released any version 0.9.0 The current version is indeed 0.8.1 both in the github and on pypi website (used when you type pip install commands). Have you maybe clone and install the package from source (and setting the version to 0.9.0 at some point) ? I see that it downloads from piwheel website, that I did not know. Yet, only v0.8.1 is available there as well. So, I do not know how come there is that specific version that interfers. sorry
