TensorFlow GPU Linux 安装

Question

这是我得到的错误：

import tensorflow
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.5/dist-packages/tensorflow/__init__.py", line 23, in <module>
from tensorflow.python import *
File "/usr/local/lib/python3.5/dist-packages/tensorflow/python/__init__.py", line 48, in <module>
from tensorflow.python import pywrap_tensorflow
File "/usr/local/lib/python3.5/dist-packages/tensorflow/python/pywrap_tensorflow.py", line 28, in <module>
_pywrap_tensorflow = swig_import_helper()
 File "/usr/local/lib/python3.5/dist-packages/tensorflow/python/pywrap_tensorflow.py", line 24, in swig_import_helper
_mod = imp.load_module('_pywrap_tensorflow', fp, pathname, description)
 File "/usr/lib/python3.5/imp.py", line 242, in load_module
return load_dynamic(name, filename, file)
File "/usr/lib/python3.5/imp.py", line 342, in load_dynamic
return _load(spec)
ImportError: libcudart.so.7.5: cannot open shared object file: No such file or directory

谁能告诉我如何在ubuntu 16.04平台上一步一步安装？

Answer 1

您丢失了环境变量。请参阅github issue。更多信息请参考post。

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

Answer 2

如果您使用的是 anaconda，请在您的 anaconda 提示符下运行此命令

conda install -c anaconda tensorflow-gpu

这还将为您安装cuda toolkit 和cudnn，一切顺利
