CuPy - 导入错误 - 未找到 nvidia lib

尝试导入 CuPy 时出现以下错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/cupy/__init__.py", line 20, in <module>

original error: libnvidia-fatbinaryloader.so.375.82: cannot open shared object file: No such file or directory

我尝试按照建议重新安装 CuPy。此外，我尝试将 libnvidia-fatbinaryloader.so.375.82 文件从 /usr/lib/nvidia-375 复制到 /usr/local/cuda-8.0/lib64/，但没有成功。

事实上，当我将该文件复制到 /usr/local/cuda-8.0/lib64/ 时出现此错误（尝试创建数组时）：

>>> import cupy as cp

>>> x_gpu = cp.array([1, 2, 3])

我的 CUDA 版本：8.0

Ubuntu 16.04

Python：2.7

有人能帮忙吗？如果可能的话，我想避免重新安装 CUDA。如果您需要更多信息来解决问题，请随时询问。谢谢！
