【问题标题】:Tensorflow with CUDA: ImportError带有 CUDA 的 TensorFlow:ImportError
【发布时间】:2017-06-04 10:25:45
【问题描述】:

我已经按照 NVIDIA(Ubuntu 16.04 Desktop,GTX 970)本教程中的说明逐步安装了 TensorFlow:

http://www.nvidia.com/object/gpu-accelerated-applications-tensorflow-installation.html

每个步骤都没有错误地完成,但是如果我之后尝试在 Python 中导入 TensorFlow,我总是会收到以下错误消息:

>>> import tensorflow as tf
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/tensorflow/__init__.py", line 24, in <module>
    from tensorflow.python import *
  File "/usr/local/lib/python2.7/dist-packages/tensorflow/python/__init__.py", line 72, in <module>
    raise ImportError(msg)
ImportError: Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/tensorflow/python/__init__.py", line 61, in <module>
    from tensorflow.python import pywrap_tensorflow
  File "/usr/local/lib/python2.7/dist-packages/tensorflow/python/pywrap_tensorflow.py", line 28, in <module>
    _pywrap_tensorflow = swig_import_helper()
  File "/usr/local/lib/python2.7/dist-packages/tensorflow/python/pywrap_tensorflow.py", line 24, in swig_import_helper
    _mod = imp.load_module('_pywrap_tensorflow', fp, pathname, description)
ImportError: libcudart.so.8.0: cannot open shared object file: No such file or directory


Failed to load the native TensorFlow runtime.

我已将 CUDA-Toolkit 安装到 /opt/cuda/toolkit(也是 cuDNN)。 我已经尝试过符号链接:

sudo ln -s /opt/cuda-toolkit /usr/local/cuda
sudo ln -s /opt/cuda-toolkit /usr/local/cuda-8.0

或者这个:

sudo export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/opt/cuda-toolkit/lib64:/opt/cuda-toolkit/extras/CUPTI/lib64
sudo export CUDA_HOME=/opt/cuda-toolkit

但错误仍然存​​在。谁能给我提示为什么会发生此错误? 非常感谢:)

【问题讨论】:

  • 你安装的是什么版本的TensorFlow?可通过python -c 'import tensorflow;print tensorflow.__version__'查询

标签: python ubuntu tensorflow


【解决方案1】:

我在具有类似硬件 (GTX 970M) 的机器上遇到了类似的问题,我使用以下帖子中提供的步骤解决了它: https://askubuntu.com/a/278840

在我的情况下,唯一的区别是在 nvidia.conf 文件中我只添加了以下行: /usr/local/cuda-8.0/lib64

然后运行:sudo ldconfig

希望对你有帮助:)

【讨论】:

  • 就是这样 :D 非常感谢!
