How to categorize image with Python and Tensorflow?

I am new to using Machine Learning with Tensorflow in CNN. I have a problem, when I try to make a CNN they give me the images in a folder and the labels in a CSV and I don’t know how to categorize the images based on that CSV to then train the model with Tensorflow.

​

Images are in a single training folder with the names a bit random.

​

Labels are in CSV that contains two columns: Image name and the associated label.
