ubuntu - ImportError : libcublas. so.9.0 : cannot open shared object file: No such file or directory (UBUNTU 16. 04)

Question

我正在尝试通过原生 pip3 安装方法安装 Tensorflow GPU 版本。安装成功，没有任何错误。但是，在验证安装时，我收到了上述错误。

ImportError: libcublas.so.9.0: cannot open shared object file: No such file or directory

During handling of the above exception, another exception occurred:

假设目标系统(您的计算机)已安装 CUDA 9 并因此可在运行时动态加载，您通过 pip(官方)下载的轮子已创建。

错误评估 libcublas.so.0无法导入( ImportError )，这意味着 .so找不到文件(动态库)。
因此，您只需在系统上安装 CUDA 9 即可使其正常工作。
沉迷于cuda，然而，你还需要安装cudnn v7.0 是 NVIDIA 创建的深度神经网络库(tensorflow 在内部使用)。

官方指南中列出了所有安装步骤:https://www.tensorflow.org/install/install_linux
