nbpapaya not working in jupyter notebook tutorial

@akeshavan --

nbpapaya's Overlay is giving an error in our jupyter notebook tutorial.
Here is the code:

import os
import pandas as pd
from nbpapaya import Overlay

df = pd.DataFrame(depths, columns=["depth"])
df.to_csv('depths.csv', index=False)

def getMeshOpts(vtk_file, csv_file, vmin, vmax, threshold):
    cols = pd.read_csv(csv_file).columns.tolist()
    MeshOpts = {}
    MeshOpts[os.path.abspath(vtk_file)] = {  
                      "filename": os.path.abspath(csv_file),
                      "colormin": "#0000FF", 
                      "colormax": "#FF0000",
                      "vmin": vmin,
                      "vmax": vmax,
                      "key": cols[0],
                      "key_options": cols,    
                      "threshold": threshold,
                      "mesh_transparency": 1,
                      "mesh_visible": True,
                      "overlay_transparency": 1
                  }
    return MeshOpts

MeshOpts = getMeshOpts(surface_file, "depths.csv" , 2,10,2)
Overlay(MeshOpts)

And here is the resulting error:

Could it be due to the difference in installations below?:

In the Dockerfile.mindboggle.complete file, nbpapaya is installed here:

USER $NB_USER
WORKDIR /opt
RUN conda install -y flask && \
    git clone https://github.com/akeshavan/roygbiv && \
    cd /opt/roygbiv && \
    git checkout fbbf31c29952d0ea22ed05d98e0a5a7e7d0827f9 && \
    python setup.py install && \
    cd /opt && \
    git clone https://github.com/akeshavan/nbpapaya && \
    cd /opt/nbpapaya && \
    git checkout 60119b6e1de651f250af26a3541d9cb18e971526 && \
    python setup.py install && \
    rm -rf /opt/roygbiv /opt/nbpapaya

whereas in our original MIT nipype workshop tutorial, you installed nbpapaya as follows:

RUN git clone https://github.com/akeshavan/nbpapaya && cd nbpapaya && git submodule update --init --recursive && python setup.py install
