Unable to init server: Could not connect: Connection refused. YOLO on Google Colab

Question

I'm trying to test out YOLO on google colab for the first time and keep running into this odd error:

This is the line of code that I run:

!./darknet detector test data/obj.data cfg/yolov3_custom.cfg /mydrive/yolov3/backup/yolov3_custom_last.weights /mydrive/images/I5.png -thresh 0.3

Answer 1

I also faced the same, but resolved by updating "config file". There might be some unbalanced "[" or "#" characters.

Solution 1: Update your config file as in this format 👉 https://github.com/pjreddie/darknet/blob/master/cfg/yolov3.cfg

Solution 2: For some, using -dont_show flag in detection command has worked.

eg: !./darknet detector test data/obj.data cfg/yolov3_V1_config.cfg /mydrive/yolov3_V1_config_last.weights /mydrive/yolov3/Poachers/pic2.jpg -thresh 0.3 -dont_show

Answer 2

In yolov3_custom.cfg file, uncomment the two lines under # Testing

# Testing
batch=1
subdivisions=1
