Issue

• What did you do?

• Converted TensorFlow model to ONNX over this command python -m tf2onnx.convert --saved-model ./checkpoints/yolov4.tf --output model.onnx --opset 11 --verbose and then imported the output file and then i changed the input and output from the sample provided by Microsoft

• What happened?

• This is the output

• Model location: .....assets\Model\nsfw_mobilenet.onnx
  Default parameters: image size=(416,416)
  System.InvalidOperationException: Input shape mismatch: Input 'input' has shape 1,224,224,3, but input data is of length 519168.

• What did you expect?

• it should work

and here is the onnx file
