Converting torch.RNN to TVM Relay about tvm

[kaimast]

Oh d'uh. RNN also takes a regular tensor as input...

However, now I get this error. Can I not convert an entire neural network into a relay? Do i have to do it layer by layer?

I don't think we support RNN to relay now.

[kaimast]

I figured. Is it planned for a future release?

[yinghai]

As far as I understand, this is not planned. If you are interested, you are welcome to help.
