I'm trying to convert mxnet model to tensorflow, so at first, I'm trying to convert my mxnet model to IR and it got stuck.

It seems that the UpSampling op is not supported in mxnet parser, is there any plan to add it for mxnet parser? or could you please provide other suggestion to convert this mxnet model to tensorflow? Thanks!
