I had to use
return 1 - np.asarray(dprod.multiply(magnitude))

Am I doing something wrong? I'm using python 2.7 and virtualenv.

Thanks for the feedback! For my own sanity, did you install with requirements.txt?

cd pysparnn
pip install -r requirements.txt
python setup.py install

I have noticed that the sparse matrix methods change a bit from version to version. If you have a patch that works on the latest versions of scipy/numpy I'd be happy to update the code!

I used requirements.txt. Will try once again. If it still doesn't work will send a PR.

@spencebeecher so I tried again and it worked, so may be I installed one of the modules without requirements.txt. Sorry my bad. I can still send PR with latest version of scipy/numpy.

Would love that!
