Incubator-mxnet: How to get the symbol of gluon's RNN model by hybridizing

[everwind]

I follow the instruction of http://gluon.mxnet.io/P14-C05-hybridize.html#, but fail. the error message is:
File "/usr/lib/python2.7/site-packages/mxnet-0.11.0-py2.7.egg/mxnet/gluon/block.py", line 312, in __setattr__
super(HybridBlock, self).__setattr__(name, value)
File "/usr/lib/python2.7/site-packages/mxnet-0.11.0-py2.7.egg/mxnet/gluon/block.py", line 177, in __setattr__
self.register_child(value)
File "/usr/lib/python2.7/site-packages/mxnet-0.11.0-py2.7.egg/mxnet/gluon/block.py", line 327, in register_child
str(block), str(type(block))))
ValueError: Children of HybridBlock must also be HybridBlock, but RNN(100 -> 100, TNC, num_layers=2, dropout=0.2) has type . If you are using Sequential, please try HybridSequential instead.
I can not find the HybridSequential RNN in source code of gluon

RNN is not a HybridBlock so you cannot use it as a children of a HybridBlock.

This is currently a limitation due to sym.RNN doesn't support CPU. RNN will be changed to a hybridblock in the future.

@piiswrong Any ETA for this feature?

[aidan-plenert-macdonald]

@piiswrong Is this feature available now?

[Matafight]

looking forward to this new feature

same here. thanks!

same here.

[QiXuanWang]

is it still a limitation yet? Can someone post a workaround?
