Hi, I’m trying to apply a Bisenetv2 model based on Python TensorRT 7. The model I’ve used is Bisenetv2, and it’s already converted from TensorFlow pb to onnx with tf2onnx. The model worked fine when I used FP32 and FP16 model.
However, when I use INT8, TensorRT outputs an error message “IndexError: _Map_base::at” when executing “builder.build_engine(network, config)”.
The following information is the setting in my computer:
- Linux distribution: Ubuntu 16.04
- GPU: 2080Ti
- Nvidia driver version: 440.33.01
- CUDA version: 10.2
- CuDNN version: 8.0.4
- Python version: Python 3.5.2
- TensorFlow version: 1.14.0
- onnx version: 1.6.0
- tf2onnx version: 1.5.4
- TensorRT version: 184.108.40.206
The attachment contains the code and the model I’ve used.

I inspect the dimension of the input image and the model, but still cannot figure out the problem. Can someone help? Thank you.
