module 'spartan' has no attribute 'SpecGreedy'

[Longyichen]

When I use the SpecGreedy in https://github.com/BGT-M/spartan2-tutorials/blob/master/SpecGreedy.ipynb as this:

# create a anomaly detection model
sg = st.SpecGreedy(stensor)
sg.run(bipartite=True, T=3)

It has error that:

  1 # create a anomaly detection model

----> 2 sg = st.SpecGreedy(stensor) 3 sg.run(bipartite=True, T=3)

AttributeError: module 'spartan' has no attribute 'SpecGreedy'
