Question

我正在尝试使用Nvidia Docs中的说明在NVidia jetson平台上安装tensorflow。我最初按照文档中的描述运行follwong命令来安装依赖项：

pip3 install -U numpy grpcio absl-py py-cpuinfo psutil portpicker six mock requests gast h5py astor termcolor protobuf keras-applications keras-preprocessing wrapt google-pasta

此后，我运行命令使用“ --extra-index-url”和提供的URL从NVidia安装特定版本的tensorflow-gpu：

pip3 install --extra-index-url https://developer.download.nvidia.com/compute/redist/jp/v42 tensorflow-gpu==1.13.1+nv19.5

每次我运行此命令时，都会引发一个错误，我相信这是因为似乎要检查NVidia URL上的某个依赖项（它们显然不存在于此）。我重新安装了依赖关系，或者安装了错误中提到的特定依赖关系，当我再次运行该命令时，它将为另一个（看似随机的）依赖关系引发错误。错误消息示例：

使用“ --extra-index-url”安装pip3无法解决依赖关系
