在Mac OS（10.12.1）上安装TensorFlow的问题

Question

我花了三个多小时安装启用GPU的TensorFlow，但是还没有成功。

我按照"pip"安装指南进行操作。

以下是我完成的任务列表： 1.1 下载并安装CUDA工具包（.dmg v8.0版本） 1.2 下载并解压CUDA深度神经网络（cuDNN v5版本） 1.3 复制文件

cd ~/Downloads/cuda
sudo mv include/cudnn.h /Developer/NVIDIA/CUDA-8.0/include/
sudo mv lib/libcudnn* /Developer/NVIDIA/CUDA-8.0/lib
sudo ln -s /Developer/NVIDIA/CUDA-8.0/lib/libcudnn* /usr/local/cuda/lib/

2.1 设置变量

export CUDA_HOME=/usr/local/cuda
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$CUDA_HOME/lib64:$CUDA_HOME/extras/CUPTI/lib64"
export DYLD_LIBRARY_PATH="$CUDA_HOME/lib"
export PATH="$CUDA_HOME/bin:$PATH"

export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/mac/gpu/tensorflow_gpu-0.12.0rc0-py2-none-any.whl

3.1 安装pip

sudo easy_install pip

3.2 安装TensorFlow

sudo pip install tensorflow --ignore-installed numpy

3.3 安装二进制文件

sudo pip install --upgrade $TF_BINARY_URL

最后，当我想检查TensorFlow是否正常工作时，我会进入Python并导入它：

>>> import tensorflow as tf

这里是我收到的完整错误信息：

有什么想法吗？

看起来很简单

sudo pip uninstall tensorflow
sudo pip install tensorflow --ignore-installed numpy

解决了问题...
