Dataset Size: 0 ZeroDivision error

Hey, I'm training my custom dataset of four classes and for some reason .train() throws the following error
cfg/yolo_custom.cfg parsing /home/iot/darkflow/data/ann/
Parsing for ['Apple', 'Cucumber', 'Tomato', 'Carrot']

Statistics:
Dataset size: 0
Dataset of 0 instance(s)

ZeroDivisionError: division by zero

I've rechecked my dataset and all the jpg files have a corresponding text file.
My options dictionary looks like this
options = {"model": "cfg/yolo_custom.cfg",
"load": "bin/yolo.weights",
"batch": 8,
"epoch": 100,
"gpu": 0,
"train": True,
"verbalize":True,
"annotation":"/home/iot/darkflow/data/ann/",
"dataset": "/home/iot/darkflow/data/images/"}

I figured that the my annotation file format is different from yours. While my is as in .txt format yours is .xml.
could it be because of this?

Hi If you made .txt format, you have to convert to .xml with same parameter

After convert, if raise same problem, you also change some DarkNet code.

See this link,
thtrieu/darkflow#879

That's why, most of people occured Zero division error
