The following folder structure is required to run the retraining process.
#### Before Preprocessing:
Assumption: Your pictures from coco is in jpg files in the `cocoapi/images/train/` subfolder and the coco annotation files are in the `cocoapi/annotations/train/` subfolder.
```
cocoapi/
images/
train/
*.jpg
annotations/
train/
instances_train2017.json
captions_train2017.json
```
#### After Preprocessing:
*[exract_multilabel_pics.py](/preprocessing/coco_preprocessing/extract_multilabel_pics.py) will create the following folders and files (images for multilabel training):
```
cocoapi/
multilabel_outer/
multilabel_images/
*.jpg
```
*[categories_of_pictures.py](/preprocessing/coco_preprocessing/categories_of_pictures.py) will create the following folders and files (labels for multilabel training):
```
cocoapi/
images_txt/
*.txt
```
*[categories_labels.py](/preprocessing/coco_preprocessing/categories_labels.py) will create the following file (categories of coco):
```
cocoapi/
labels.txt
```
