转换命令如下：

trtexec --onnx=glintr100.onnx --minShapes=input:1x3x112x112 --optShapes=input:4x3x112x112 --maxShapes=input:8x3x112x112 --workspace=2048 --saveEngine=glintr100.onnx_dynamic.engine --fp16

环境信息

TensorRT版本：7.2.2.3
系统：Ubuntu16.04

解决办法

是因为TensorRT版本的原因，所以通过更换版本可以解决这个问题。这个7.2.2.3的版本是我从NVIDIA官网下载的TensorRT，由于我的TensorRT需要与我triton-server的版本匹配，所以我从NVIDIA上pull一个对应版本的镜像

#拉取tensorrt镜像
docker pull nvcr.io/nvidia/tensorrt:21.03-py3
#激活镜像
docker run --gpus all -it --rm -v model:/model nvcr.io/nvidia/tensorrt:21.03-py3
#将onnx模型转换为engine
cd /model
trtexec --onnx=glintr100.onnx --minShapes=input:1x3x112x112 --optShapes=input:4x3x112x112 --maxShapes=input:8x3x112x112 --workspace=2048 --saveEngine=glintr100.onnx_dynamic.engine --fp16

这个版本镜像的TensorRT能够转换成功
