How do we implement QKNN algorithm on our dataset

What could be the steps to implement a distance based classifier (eg Qknn) on our dataset using quantum computing?

I read a paper on "Distance based classifier using Iris dataset". I wanted to implement the same on my machine considering any random dataset taking 2 datapoints and 2 features as considered in the paper. SO do i need to make some changes in the gates or where do i need to put my data values?
