Many of the algorithms present in pybgs raise an exception when invoked on Google Colab

[ghost]

Describe the bug
Many of the algorithms raise an exception when invoked. I have commented such algorithms in the code attached.
The error for one of these algorithms is pasted below:

OpenCV Version: 3.4.15
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
[<ipython-input-7-a2ee577a945b>](https://localhost:8080/#) in <module>
     41 algorithms.append(bgs.ViBe())
     42 algorithms.append(bgs.CodeBook())
---> 43 algorithms.append(bgs.FuzzySugenoIntegral())
     44 #algorithms.append(bgs.FuzzyChoquetIntegral())
     45 #algorithms.append(bgs.LBSimpleGaussian())

AttributeError: module 'pybgs' has no attribute 'FuzzySugenoIntegral'

To Reproduce
I have attached a publicly accessible Google Colab notebook that reproduces the error. Google Colab Notebook

Expected behavior
Algorithms mentioned in the demo2.py should run without exception. demo2.py
