Hello there,
I'm trying to convert an mxnet model to openvino.
The input shape of the images is 96x96 in grayscale.
When I'm trying to convert it with mo_mxnet.py then I get the following error:

As I can see the converter thinks that the weight is 32, but in fact the convolution conv_rd1_down does have an input with the weight conv_rd1_down_w and the bias conv_rd1_down_b.
So the weights conv_rd1_down_w do have the right size of [32 1 3 3] so how does the model optimizer get the weight size of 32?
I attached the params file and the symbol for completeness.
The Command I called the optimizer:
python mo_mxnet.py --input_model hybridNet-0000.params --input_shape [1,1,96,96] --input Input --log_level=DEBUG
thanks in advance

I have asked our developers to take a look at this
I will let you know what they say.
Thanks
