DNN/TF(EfficientNet): add Fill layer, ONNX: add Split layer default axis + const-propagation #19696
Description
System information (version)
- OpenCV => 4.5.1
- Operating System / Platform => Mac OS
- Compiler => Xcode
Detailed description
Using efficient lite model trained in Keras, then exported through tf crashes upon load using DNN. I've tried several different avenues. tf1 / tf2/ onnx. None seem to work. I've included 2 attempts through tensor flow. Both have different crashes.
Attempt 1.
.1/modules/dnn/src/tensorflow/tf_importer.cpp:591: error: (-2:Unspecified error) Input [batch_normalization_1/cond/ones_like] for node [batch_normalization_1/cond/FusedBatchNorm] not found in function 'getConstBlob'
Empty model can be accessed here.

Attempt 2.
/opencv/opencv-4.5.1/modules/dnn/src/dnn.cpp:614: error: (-2:Unspecified error) Can't create layer "model_2/global_max_pooling2d_1/Max" of type "Max" in function 'getLayerInstance'

Attempt 3.
This was done using tf2Onnx. So converting directly from Keras to Onnx.
