Darknet: Couldn't open file while trainning

Created on 2 Oct 2018 · 5Comments · Source: pjreddie/darknet

I wish to train a model to detect traffic speed sign 110km/h with the darknet v3 weights
./darknet detector train cfg/110.data cfg/speed-sign-yolov3-tiny.cfg yolov3.weights
However, I am getting this error which saying my dataset is not found

Loading weights from yolov3.weights...Done!
Learning Rate: 0.001, Momentum: 0.9, Decay: 0.0005
Saving weights to backup//speed-sign-yolov3-tiny_final.weights

The problem is all the filename stated in train / test.txt were replaced. Note on the following snippet of my train.txt

The jpg in the middle of each filename was replaced by YOLO to txt
What actually happens?

try:
dos2unix data/train.txt
if you were using files created in windows

You can try this: https://github.com/AlexeyAB/darknet
I trained successfully by using AlexeyAB darknet.
The paths in tutorial is for Windows, pay attention about it if you are in Linux.
