[Deleted user]

I would like to use my own dataset to train the mode, in order to do that i need to create my own data_manager function.
Here's how my dataset looks like

Train Folder:
image-1.jpg
image-2.jpg
image-3.jpg

Test Folder:
image-1.jpg
image-2.jpg
image-3.jpg

---

JSON files for test and train look like

{
"train": {
"cat": [
--------Train Images----
--------Train Images----
]
},
"test": {
"cat": [
--------Test Images----
--------Test Images----
]
}
}
