Reloading saved model in gluon

I have symbol file and parameters file saved using .export method.
So now how can I reload that same model??
According to documentation I can do so using gluon.SymbolBlock.imports, but it’s throwing error as SymbolBlock has no attribute 'imports'.

What version of MXNet are you using and how did you build/install mxnet.

Seems to work fine for me.

>>> import mxnet

>>> mxnet.__version__

'1.4.1'

>>> 'imports' in dir(mxnet.gluon.SymbolBlock)

True

Actually I had python 3.7 where the latest mxnet version is 1.2… switching to python 3.6 solved the issue with mxnet 1.5 (or 1.4)
