".yml" file "prefix" question (How to Implement Yolo V3 Object Detection on Windows with GPU)

Question

(This is my 1st attempt with Anaconda / Python / YOLO / Object Detection)

I follow this YouTube tutorial. (as said from time-tag 2:00) I downloaded Anaconda Python 3.7.3, copied yolo.yml from the tutorial repository to C:\yolo\, & run conda create env -f yolo.yml. Until here: OK.

But, at this point, I realized that the last line in yolo.yml file is: prefix: C:\Users\Ritesh\Anaconda3.1\envs\yolov3. The first line is: name: yolov3.

My computer C:\Users\ folder has Amit folder (my name) and not Ritesh and, as it seems, conda create env -f yolo.yml created the env under C:\Users\Amit\Anaconda3\envs\yolov3\.

Shortly, my question is: What is the meaning/purpose of the prefix line? How it comes to play? Do I have to fix something at this point? & if the answer is YES, than how do I do it?
