Assignment 3 Part 2: YOLO Object Detection on PASCAL VOC
Due date: Thursday, November 5th, 11:59:59PMCreated by Daniel McKee and Maghav Kumar. Updated by Aiyu Cui and Jeffrey Zhang.
Part 2 Task
In this part of the assignment you will implement a YOLO-like object detector on the PASCAL VOC 2007 dataset to produce results like in the above image. The goal is to help you understand the fundamentals of training an object detector, gain experience with PyTorch as well as teaching how to use pretrained models provided by the deep learning community.
How to start

As you start this part, you will realize that this is a more computationally intensive assignment than what you are used to. We will soon be providing some initial expectations of mAP values as a function of epoch so you can get an early idea whether your implementation works without waiting a long time for training to converge.
You will need a GPU for this assignment, hence you should use the provided Google Cloud credits.
Environment Setup (Local)
If you will be working on the assignment on a local machine then you will need a python environment set up with the appropriate packages. We suggest that you use Conda to manage python package dependencies (https://conda.io/docs/user-guide/getting-started.html).
Unless you have a machine with a GPU, running this assignment on your local machine will be very slow and is not recommended. Please use Google Cloud for this assignment.
Be careful using GOOGLE CLOUD!! Do not use all your credits! We will soon post on Piazza how long the training is expected to take on the Cloud, but initial estimates tell us a fully trained model should take around 7-8 hours.
Data Setup (Local)Once you have downloaded the zip file, go to the Assignment3 folder and execute the download_data script provided:
