运行服务器上的 TensorFlow Federated 时出错

Question

当我尝试在服务器上加载 Tensorflow Federated 库时出现以下错误。我正在使用 tensorflow_federated 版本 0.13.1

我服务器上的Cuda版本是10.2。 Cudnn库7.6以上.

问的 "libnvinfer.so.6" 是什么？

我认为您缺少一些库 "libvinfer"，例如要继续安装 cuda 10.1，您必须安装这些包

# Install TensorRT. Requires that libcudnn7 is installed above.
sudo apt-get install -y --no-install-recommends \
    libnvinfer6=6.0.1-1+cuda10.1 \
    libnvinfer-dev=6.0.1-1+cuda10.1 \
    libnvinfer-plugin6=6.0.1-1+cuda10.1
