I'm having trouble loading YOLOv3's into OpenCV's dnn module. I'm following this tutorial but instead of using the full YOLOv3 I'm using Tiny YOLOv3 trained on my own dataset. I run into the following error:
[ERROR:0] global /io/opencv/modules/dnn/src/dnn.cpp (3066) getLayerShapesRecursively OPENCV/DNN: [Concat]:(concat_20): getMemoryShapes() throws exception. inputs=2 outputs=1/1

Traceback (most recent call last):

layerOutputs = net.forward(ln)
cv2.error: OpenCV(4.2.0) /io/opencv/modules/dnn/src/layers/concat_layer.cpp:102: error: (-201:Incorrect size of input array) Inconsistent shape for ConcatLayer in function 'getMemoryShapes'I suspect the problem is with the network and the input loading image - but I'm loading a 416x416 image which should be resized in darknet. I suspect there's another problem with slicing or the cfg file. When running it through darknet works well.
Steps to reproduce
- Load code from this link
- cfg file can be found here
- weights etc can be found here
