安装 tensorflow 时出错，在 ubuntu 中服务

Question

我正在安装 Tensorflow 服务，为此我必须在 ubuntu 中安装 tensorflow。我在tf 根目录中运行了./configure 命令。 这是输出：

Please specify the location of python. [Default is /usr/bin/python]:

Auto-Configuration Error: Cannot find cudnn.h at /usr/lib/x86_64-linux-gnu/include/cudnn.h
.

没有名为/usr/lib/x86_64-linux-gnu/include 的文件夹。我确实有libcudnn.so 文件在/usr/lib/x86_64-linux-gnu/ 和cudnn.h 在文件夹/usr/include 中。我不知道配置文件是如何生成路径的，但它找不到 cudnn，尽管我已经成功安装了 caffe，其 CMakeLists.txt 可以轻松找到 cuda 和 cudnn 安装的路径。我该如何解决这个问题？

Answer 1

假设您确实安装了cudnn。
使用 -
which nvcc

找到你的 cuda 的安装位置

在我的情况下它返回 - /usr/local/cuda-6.5/bin/nvcc

所以cudnn.h位于/usr/local/cuda-6.5/include（如果安装了cudnn）

在配置 tensorflow 时，系统会询问您 -
Please specify the location where cuDNN library is installed. Refer to README.md for more details. [Default is /usr/local/cuda]:

这里你必须明确指定cudnn的位置。
就我而言，它是/usr/local/cuda-6.5/include/。
