ubuntu 18.4 (nv-tensorrt-repo-ubuntu1804-cuda10.2-trt7.0.0.11-ga-20191216_1-1_amd64.deb) debian に tensorRT 7.0 をインストールしようとしていました。

ドキュメントhttps://docs.nvidia.com/deeplearning/tensorrt/install-guide/index.html#installing-debianに従いました。

libnvinfer7 で以下のエラーが発生します。これを世界中で探して、見つけることができず、時間と睡眠を失いました。これで私を助けてください：

さて、「sudo apt-get install python3-libnvinfer-dev」を試してみました

デフォルトでは、システムはlibnvinferのバージョンを最新のものにアップグレードしようとします (CUDA のバージョン 11.x へのアップグレードを含む)。

そのため、最初に必要なバージョンをインストールしてから、依存関係が満たされない原因となる可能性のある自動アップグレードの試行を制限するためにそれらを保留する必要があります。

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

その後、問題なく tensorrt をインストールできます。

sudo apt-get install tensorrt
