libcublas.so.9.0：在 ubuntu 17.10 中运行 tensorflow 时无法打开共享对象文件

Question

我尝试过 cuda 9，但 tensorflow 似乎不起作用。现在，我安装了 cuda 8，设置了环境变量和其他一堆东西，但这个错误仍然存​​在。帮帮我！

>>> import tensorflow as tf

Failed to load the native TensorFlow runtime.

在您的系统中找到 libcublas.so.9.0，可能在 /usr/local/cuda-9.0/lib64 下。现在添加到您的~/.bashrc 文件中：

export LD_LIBRARY_PATH=/path/to/cuda/lib64

然后，您应该从该错误继续前进，并看到一个找不到 libcudnn.so 的错误。确保您已安装 CUDNN 库并按照与 libcudnn.so 相同的步骤进行操作（libcudnn 的实际名称类似于 libcudnn.so.7，具体取决于您的版本）。

这里的关键是正确设置LD_LIBRARY_PATH。

如果您仍然遇到问题，请确保重新启动终端会话并输入 echo $LD_LIBRARY_PATH 以验证所有设置更改均已正确应用。
