Cannot infer shapes or values for node "output/YoloRegion"
I was trying to convert the yolo v2 model to IR representation.
In the YOLO cfg file, I could see softmax is 0 in the detection layer. After setting 0 in do_softmax param in the region layer in the JSON file, I could see the following error in the conversion of IR representation.
[ ERROR ] Cannot infer shapes or values for node "output/YoloRegion". [ ERROR ] 'do_softmax' [ ERROR ] [ ERROR ] It can happen due to bug in custom shape infer function <function RegionYoloOp.regionyolo_infer at 0x7fa37426a598>. [ ERROR ] Or because the node inputs have incorrect values/shapes. [ ERROR ] Or because input shapes are incorrect (embedded to the model or passed via --input_shape). [ ERROR ] Run Model Optimizer with --log_level=DEBUG for more information. [ ERROR ] Stopped shape/value propagation at "output/YoloRegion" node.
