Jetson安装Python3.8 tensorrt库

背景

我在运行项目：https://github.com/wang-xinyu/tensorrtx/tree/master/yolov7/yolov7_trt.py时，遇到报错：

Traceback (most recent call last):
  File "yolov7_trt.py", line 17, in <module>
    import tensorrt as trt
ModuleNotFoundError: No module named 'tensorrt'

在执行完：

sudo apt update
sudo apt install nvidia-tensorrt

还是出现如下类似错误：
