Do I need to changed CudnnLSTM to basic LSTM cells before converting to TensorRT engine

I have train my model with CudnnLSTM, and would like to convert to TensorRT engine, I wonder if I need to convert the CudnnLSTM to BasicLSTMCell or BlockLSTMCell before doing so.

I’m using Tensorflow 1.8, is there any example of conversion if that is required.

Thanks Joseph
