issue with cvxpy.Variable functions in example code

[b-ganesh]

Hi there, I am running into an issue during the allocation step when I try to run your example code. I am currently using Python 3 and I am getting the following error. Any help on this issue would be much appreciated- thanks so much!

TypeError Traceback (most recent call last)
