Key Questions Answered
What layers does TensorRT support for RNNs?
TensorRT supports RNNv2, MatrixMultiply, ElementWise, and TopK layers, allowing for flexible model configurations. This support enables developers to create efficient inference engines tailored to their specific deep learning applications.
How do you set weights for RNNv2 layers in TensorRT?
For RNNv2 layers in TensorRT, weights for each gate and layer must be set separately. The input format required for RNNv2 is BSE, which stands for Batch, Sequence, and Embedding, ensuring proper data handling during inference.
How can you serialize a TensorRT engine?
You can serialize the TensorRT engine to a memory block, which can then be saved to a file or streamed. This process eliminates the need to perform the optimization step again, thus saving time during deployment.
Can TensorRT be used with Python?
Yes, although the sample in the video is built using C++, the same implementation can be achieved using the TensorRT Python API, providing flexibility for developers who prefer Python over C++.

Common Pitfalls
1
Failing to set weights for each gate and layer separately in RNNv2 can lead to incorrect model behavior.
This mistake often occurs when developers assume a single weight configuration is sufficient. Properly configuring weights is essential for the RNN to function correctly.
