ImportError：libcublas.so.9.0：无法打开共享对象文件：即使路径中存在libcublas.so.9.0，也没有这样的文件或目录

Question

我的机器信息：

• nvcc --version:

  nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2017 NVIDIA Corporation Built on Fri_Sep__1_21:08:03_CDT_2017 Cuda compilation tools, release 9.0, V9.0.176

• cuda驱动版本

  • 版本 - 9.2
  • 文件 - nvidia-diag-driver-local-repo-rhel7-396.26-1.0-1.x86_64.rpm

• cat /etc/redhat-release：CentOS Linux 版本 7.5.1804（核心）

cat .bashrc 包括以下内容

PATH=$PATH:/usr/local/cuda/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64
CUDA_HOME=$CUDA_HOME:/usr/local/cuda

在此之后，如果我尝试导入 torch 或 torchvision，它工作正常。但是我导入了tensorflow，它没有导入

我的tensorflow版本如下：

• 张量板==1.8.0
• tensorflow-gpu==1.8.0

我收到以下错误：

>>> import tensorflow

    return _load(spec)
ImportError: libcublas.so.9.0: cannot open shared object file: No such file or directory

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.

See https://www.tensorflow.org/install/install_sources#common_installation_problems

for some common reasons and solutions.  Include the entire stack trace
above this error message when asking for help.

但是/usr/local/cuda/lib64 有以下内容：

• libcublas_device.a
• libcublas.so
• libcublas.so.9.0
• libcublas.so.9.0.176
• libcublas_static.a

我无法找出问题所在。许可与此有关吗？后来我将上述文件的所有者和权限更改为当前和755。仍然得到同样的错误。

只需将上述路径添加到您的 LD_LIBRARY_PATH 为：

 export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
