Output not saving in json format

[saikrishnadas]

Hey, I need to save my image ouput in json format.

Code i ran: ( the same way it was mentioned in the page)

./darknet detect cfg/custom-yolov4-detector.cfg backup/custom-yolov4-detector_final.weights data/test_image.jpg -dont-show -out -out result.json < data/train.txt

But no ouput named result.json is saved.

It works with txt file but not with .json file

./darknet detect cfg/custom-yolov4-detector.cfg backup/custom-yolov4-detector_final.weights data/test_image.jpg -dont-show -out -out result.json < data/train.txt

Note that what you wrote is not like the example on the page.

• you have multiple -out parameters
• you have detect instead of detector
• you have a single test_image.jpg file instead of using the input in train.txt

Hey, @stephanecharette Thanks for the response. But how can I save the result to json for a single image instead of a batch of image paths written into data/something.txt

Because using the batch of images method happens to have problem while giving multiple call:

 161 yolo
[yolo] params: iou loss: ciou (4), iou_norm: 0.07, cls_norm: 1.00, scale_x_y: 1.05
nms_kind: greedynms (1), beta = 0.600000
Total BFLOPS 59.701
avg_outputs = 492276
 Allocate additional workspace_size = 52.43 MB
Loading weights from backup/custom-yolov4-detector_final.weights...
 seen 64, trained: 1920 K-images (30 Kilo-batches_64)
Done! Loaded 162 layers from weights-file
Enter Image Path:

It stops there.

So, is there any possible was to save result in json for one image instead of putting path in the .txt file

I use DarkHelp to get my json output. You can find out about it here: https://www.ccoderun.ca/darkhelp/api/ShellScripting.html
