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,没有任何问题:TensorFlow 使用 CPU。但是,如果在 Linux 机器上我运行 pythonimport tensorflow as tf
,则由于未安装 CUDA,TensorFlow 无法导入:
Traceback (most recent call last):

如何在 Linux 上使用没有 CUDA 的 TensorFlow?
I use tensorflow-gpu==1.0.0
.
我知道这个参数device_count
in tensorflow.ConfigProto
,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]))
但这没有帮助,因为import tensorflow as tf
是问题所在。
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
但更愿意在这两台机器上避免它。
