batch size is zero in tiny_yolov2 model

[jinz2014]

I got the following error when calling the import_onnx_model function. Thanks for the instruction on the modification.

ng_function = import_onnx_model(model.SerializeToString()) RuntimeError: Check '(batch_size.is_dynamic() || static_cast<size_t>(batch_size) > 0)' failed at /root/ng/src/ngraph/validation_util.cpp:316: While validating node 'Convolution[Convolution_51](Add_50: float{0,3,416,416}, C onstant_2: float{16,3,3,3}) -> (??)': Batch size is zero.

@jinz2014 did you had any luck on that? I reached the same point, not sure if ngraph supports dynamic batch size.
