如何在Linux上使用没有CUDA的TensorFlow？

问题描述

我有两台没有CUDA的计算机：一台在Microsoft Windows上运行，另一台在Linux上运行（Ubuntu 14.04 64bit / Linux 3.13.0-100-generic））

我可以在Microsoft Windows上使用没有CUDA的TensorFlow而没有任何问题：TensorFlow使用CPU。 但是，如果在Linux机器上我运行python import tensorflow as tf ，那么由于未安装CUDA，TensorFlow无法导入：

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):

    from tensorflow.python import pywrap_tensorflow

    _pywrap_tensorflow = 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

如何在Linux上使用没有CUDA的TensorFlow？

我使用tensorflow-gpu==1.0.0 。

我知道tensorflow.ConfigProto中的参数device_count ，它允许禁用GPU，例如：

import tensorflow as tf

a = tf.constant(1, name = 'a')
b = tf.constant(3, name = 'b')
c = tf.constant(9, name = 'c')
d = tf.add(a, b, name='d')
e = tf.add(d, c, name='e')

config = tf.ConfigProto(device_count={'CPU': 1, 'GPU': 0})
sess = tf.Session(config=config)
print(sess.run([d, e]))

但它没有帮助，因为import tensorflow as tf是问题。

我也知道如何安装CUDA 8：

# Install Nvidia drivers, CUDA and CUDA toolkit, following some instructions from http://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html
wget https://developer.nvidia.com/compute/cuda/8.0/Prod2/local_installers/cuda-repo-ubuntu1404-8-0-local-ga2_8.0.61-1_amd64-deb
sudo dpkg -i cuda-repo-ubuntu1404-8-0-local-ga2_8.0.61-1_amd64-deb
sudo apt-get update
sudo apt-get install cuda

但我宁愿在这两台机器上避免使用它。
