为什么找不到cudnn.h

Question

我通过anaconda安装了cudnn7.1.2，然后在https://caffe2.ai/docs/getting-started.html?platform=mac&configuration=prebuilt之后通过anaconda安装了coffe2，但它报告找不到cudn.h。

错误报告包括：

我不是Caffe2专家，但是这个错误意味着您没有安装CUDNN库。这意味着您正在尝试使用支持CUDA的咖啡馆框架，并希望安装CUDA (可能是9+版本)和相关的CUDNN库。https://docs.nvidia.com/cuda/cuda-installation-guide-mac-os-x/index.html
