dataset was pretty straightforward since you only needed to parse the path. However, many scientific and open source datasets encode their labels into binary files.

dataset from the technical requirements section is one such example. It includes the label information in the annotation.bin
(binary) and annotation.txt
(human-readable) files under the ./data/test
and ./data/train
folders. Let’s focus on the binary file and only use the human-readable copy for troubleshooting.
We will perform the following steps to do this:
