ASR model to TensorRT
Recently, I want to convert my NeMo ASR model to TensorRT. My model was trained with NeMo v0.10.2 and when I tried to quantify it to int8, it came up with an error:

> [TensorRT] WARNING: Int8 calibration in TensorRT won't be used on networks containing boolean operators or loops. Please use quantization-aware training to generate a network with Quantize/Dequantize nodes.

Then, I transform my model into NeMo v1.2.0 following [the code here](https://github.com/NVIDIA/NeMo/discussions/1680#discussioncomment-321962). It works well without any quantification. But there are still some errors when converting to int8 following [sample code](https://github.com/NVIDIA/NeMo/tree/main/examples/asr/quantization)  without any changes except model weight parameters.

> [TensorRT] ERROR: ModelImporter.cpp:720: While parsing node number 39 [QuantizeLinear -> "687"]:

And there are also many warnings like

Is there anything wrong? I would appreciate it if any help is offered!
