我试图在 ubuntu 18.4 (nv-tensorrt-repo-ubuntu1804-cuda10.2-trt7.0.0.11-ga-20191216_1-1_amd64.deb( debian 中安装 tensorRT 7.0
。按照文档 https://docs.nvidia.com/deeplearning/tensorrt/install-guide/index.html#installing-debian 进行操作。
我在 libnvinfer7 中遇到以下错误。在地球上寻找这个，找不到，失去了时间和睡眠。请帮我解决这个问题：
amarnath@amarnath-Precision-T3610:/opt/pixuate$ sudo apt install tensorrt

好吧，尝试了"sudo apt-get install python3-libnvinfer-dev">
amarnath@amarnath-Precision-T3610:/opt/pixuate$ sudo apt-get install python3-libnvinfer-dev

在 https://docs.nvidia.com/deeplearning/tensorrt/install-guide/index.html 的 TensorRT 安装部分有这样一句话：
要求 CUDA 工具包和 cuDNN 也已使用 Debian 或 RPM 软件包安装
如果使用 deb 文件安装 CUDA 工具包和 cuDNN，则应解决未满足的依赖项错误。
注意：在安装之前，请检查您要安装的 Ubuntu、CUDA 和 cuDNN 版本。在下面的安装提示中，使用了 CUDA 10.2 和 cuDNN 7.6.5。这是针对 TensorRT 7.0.0 进行测试的。
库达.deb安装
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804x86_64cuda-ubuntu1804.pin
sudo mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget http://developer.download.nvidia.com/compute/cuda/10.2/Prod/local_installers/cuda-repo-ubuntu1804-10-2-local-10.2.89-440.33.01_1.0-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu1804-10-2-local-10.2.89-440.33.01_1.0-1_amd64.deb
sudo apt-key add /var/cuda-repo-10-2-local-10.2.89-440.33.01/7fa2af80.pub
sudo apt-get update
sudo apt-get -y install cuda
CUDNN .deb安装
首先下载.deb文件：
- cuDNN Developer Library for Ubuntu18.04 (Deb(
- cuDNN Runtime Library for Ubuntu18.04 (Deb(
之后安装下载的软件包：
sudo dpkg -i libcudnn7_7.6.5.32-1+cuda10.2_amd64.deb
sudo dpkg -i libcudnn7-dev_7.6.5.32-1+cuda10.2_amd64.deb
注意：这些安装说明来自 nvidia 官方网站
默认情况下，系统将尝试将libnvinfer版本升级到最新版本(包括将 CUDA 升级到版本 11.x(。
因此，我们首先需要安装必要的版本，然后保留它们以限制可能导致未满足依赖项的任何自动升级尝试。
sudo apt-get install libnvinfer7=7.0.0-1+cuda10.2 libnvonnxparsers7=7.0.0-1+cuda10.2 libnvparsers7=7.0.0-1+cuda10.2 libnvinfer-plugin7=7.0.0-1+cuda10.2 libnvinfer-dev=7.0.0-1+cuda10.2 libnvonnxparsers-dev=7.0.0-1+cuda10.2 libnvparsers-dev=7.0.0-1+cuda10.2 libnvinfer-plugin-dev=7.0.0-1+cuda10.2 python3-libnvinfer=7.0.0-1+cuda10.2
sudo apt-mark hold libnvinfer7 libnvonnxparsers7 libnvparsers7 libnvinfer-plugin7 libnvinfer-dev libnvonnxparsers-dev libnvparsers-dev libnvinfer-plugin-dev python3-libnvinfer python3-libnvinfer-dev
之后，您可以毫无问题地安装张量：
sudo apt-get install tensorrt
我在tensorrt 8.2.5-1和cuda11.6有这个问题：
张量：取决于：libnvinfer-samples(= 8.2.5-1+cuda11.4(，但它不会被安装
通过安装cuda 11.7和tensorrt 8.4.1.5来解决。
TensorRT 安装失败，缺少 libnvinfer 样本
