The problem Patron Augury solves

The banks can use it to analyze how many churners are there so that they can inprve themselves.It makes easier for the banks to analyze and understand where they are lagging so that they can improve themselves.

Challenges we ran into

We as a team created a code to test the number of churners.We faced a bug in the code regarding the usage of various Python libraries ,which we solved later by understanding the problems.
We also had little confusion about the algorithm which we later resolved by further research.
We also had very less knowledge about the scikit learn library which we further improved by learning more about the methods in the library.
