The kernel appears to have died. It will restart automatically

Hi,

I'm really new to this, but I've followed the instruction how to install samuROI on my mac, but when I tried to run from the setup in a jupyter notebook:

%matplotlib qt4
import samuroi
import numpy

#create some random data
data = numpy.random.normal(size=(100,100,30))
morphology = numpy.random.normal(size = (100,100))

#show the gui 
app = samuroi.SamuROIWindow(data = data,morphology=morphology)
app.show()

I get the following message:

The kernel appears to have died. It will restart automatically

With python crashing and nothing else happening. I've installed all the required packages from the list into my environment.

What am I doing wrong?

Cheers, Ben
