安装tensorflow后导入错误

Question

我尝试安装链接Installing Tensor flow中给出的tensorflow

我将它安装在虚拟环境中。我收到了编辑最后给出的导入错误。

我设置了以下环境变量。

PATH=/usr/local/cuda-8.0/bin:rest/of/the/path
LD_LIBARY_PATH=/home/harshit/Drivers/cudnn5.0/cuda/:/usr/local/cuda-8.0/lib64/:/usr/local/cuda/lib64/

此外，我还尝试手动复制 cudnn 的文件，但仍然没有运气。也就是说，我在 /usr/local/cuda/lib64 和 /usr/local/cuda-8.0/lib64 中都有 libcudnn.so.5。

正如其他相关帖子中所给出的，问题通常是由于环境路径造成的，但我觉得它们在我的情况下是完全正确的，但仍然存在错误。

请帮忙！

我认为您的 libcudnn.so 文件链接不正确。

请做

$ sudo ldconfig

这将显示 /path/to/cuda-8.0/lib64 中未正确链接的文件。 这些应该是 libcudnn.so 和 libcudnn.so.5（根据您的错误）。

尝试在终端上尝试以下命令： 如果你有 cudnn v6（像我一样）：

$ cd /path/to/cuda-8.0/lib64

如果您从 NVIDIA CUDNN 包中手动复制了 libcudnn.so.6 和 libcudnn.so，请从该文件夹中删除它们。

$ sudo ln -s libcudnn.so.6.0.21 libcudnn.so.6
$ sudo ln -s libcudnn.so.6 libcudnn.so
$ sudo ldconfig

请根据您使用的cudnn版本更改文件名。
