Not able to generate IR for ssd_resnet50_512 using mxnet

Is this issue fixed? https://software.intel.com/zh-cn/node/814950

Receiving the same error while converting ssd_resnet50_512 from mxnet to IR.

@rohit167, could you try to follow the instruction here https://github.com/openvinotoolkit/openvino/blob/master/docs/MO_DG/prepare_model/convert_model/mxnet_specific/Convert_GluonCV_Models.md to convert the model?
