Darknet: Cannot load image

[anornotan]

I'm trying to reproduce this tutorial to make sure I understand how things work before training on my data, so I am using his dataset and labels.
I am not very sure how to structure the files so I guess the issue has something to do with it.
I am training on an AWS EC2 server with CUDA 8 and OpenCV 3 pre-installed.

main directory darknet

• cfg
  
  
  
  • obj.data
  
  
  • yolo-obj.cfg (copied yolo-voc.2.0.cfg and changed batch to 64, subdivisions to 8, classes to 1 and filters to 30)
  
  
  • obj.names (has exactly one word 'NFPA')
  
  
• data
  
  
  
  • nfpa
    
    
    
    
    
    • all the .jpg files and their corresponding .txt files (bounding box)
    
    
    
  
  

I am guessing obj.data is the culprit

classes= 1
train = data/nfpa/train.txt
valid = data/nfpa/test.txt
names = data/obj.names
backup = backup/

Part of my Makefile

GPU=1
CUDA=1
CUDNN=1
OPENCV=1
OPENMP=0
DEBUG=0

My issue is
I have checked the text files and the values are normal (not infinity).

Please help. Thank you!

From the screenshot it seems like you have labels (.txt) and images in same folder it should be in the form of:

• datafolder/
  
  
  
  • images/
  
  
  • labels/
  
  

train.txt should contain paths to:

• datafolder/images/000.jpg
• datafolder/images/001.jpg
• datafolder/images/XXX.jpg

and then your labels should be placed and have the structure like this:

• datafolder/labels/000.txt
• datafolder/labels/001.txt
• datafolder/labels/XXX.txt

To be able to provide better help I would like the following:

• Post a small snippet of train.txt
• Post all contents of cfg/yolo-obj.cfg
• Absolute path data folder
• Absolute path to darknet folder (I guess your screenshot answer this: home directory)
• Post one-three label files (their content)

Sorry, I forgot to update. I downloaded the VOC dataset and set it up as instructed in the README and things are working now. Before, I got my images and labels folders all mixed up. Thank you for your help :)

It doesn't have to do with the CUDA or cuDNN versions.

I have the same problem, and it worked when I used a png format, but why this happened
