Я пытался установить tenorRT 7.0 в ubuntu 18.4 (nv-tensorrt-repo-ubuntu1804-cuda10.2-trt7.0.0.11-ga-20191216_1-1_amd64.deb) debian.

документация https://docs.nvidia.com/deeplearning/tensorrt/install-guide/index.html#installing -debian .

Я получаю следующую ошибку с libnvinfer7. Искал это вокруг pl anet, не смог найти, потерял время и сон. Пожалуйста, помогите мне с этим:

Ну, попробовал «sudo apt-get install python3 -libnvinfer-dev»

В разделе установки TensorRT из https://docs.nvidia.com/deeplearning/tensorrt/install-guide/index.html есть это предложение:

требует, чтобы CUDA Toolkit и cuDNN также были установлены с использованием пакетов Debian или RPM

Если вы устанавливаете инструментарий CUDA и cuDNN с использованием файлов deb, должна быть устранена ошибка неудовлетворенных зависимостей .

ПРИМЕЧАНИЕ: Перед установкой проверьте версии Ubuntu, CUDA и cuDNN, которые вы хотите установить. В приведенных ниже советах по установке использовались CUDA 10.2 и cuDNN 7.6.5. Это протестировано для TensorRT 7.0.0.

CUDA .deb install 

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 install

Сначала загрузите файлы .deb:

  1. Библиотека разработчика cuDNN для Ubuntu18.04 (Deb)
  2. Библиотека времени выполнения cuDNN для Ubuntu18.04 (Deb)

После этого установите загруженные пакеты: 

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

ПРИМЕЧАНИЕ: Эти инструкции по установке взяты с официальных веб-сайтов nvidia
