通过Anaconda安装TensorFlow环境

安装 Anaconda :
参考 Anaconda安装

1、建立环境

建立一个 conda 计算环境名字叫tensorflow:

# Python 2.7
$ conda create -n tensorflow python=2.7
# Python 3.4
$ conda create -n tensorflow python=3.4

2、激活
激活tensorflow环境,然后使用其中的 pip 安装 TensorFlow. 当使用easy_install使用–ignore-installed标记防止错误的产生。

URL of the TensorFlow Python package
$ source activate tensorflow
(tensorflow)$  # Your prompt should change
# Ubuntu/Linux 64-bit, CPU only, Python 2.7:
(tensorflow)$ pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.8.0rc0-cp27-none-linux_x86_64.whl
# Ubuntu/Linux 64-bit, GPU enabled, Python 2.7. Requires CUDA toolkit 7.5 and CuDNN v4.
# For other versions, see "Install from sources" below.
(tensorflow)$ pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.8.0rc0-cp27-none-linux_x86_64.whl
# Mac OS X, CPU only:
(tensorflow)$ pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.11.0rc0-py2-none-any.whl

对于 Python 3.x :

$ source activate tensorflow
(tensorflow)$  # Your prompt should change
# Ubuntu/Linux 64-bit, CPU only, Python 3.4:
(tensorflow)$ pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.8.0rc0-cp34-cp34m-linux_x86_64.whl
# Ubuntu/Linux 64-bit, GPU enabled, Python 3.4. Requires CUDA toolkit 7.5 and CuDNN v4.
# For other versions, see "Install from sources" below.
(tensorflow)$ pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.8.0rc0-cp34-cp34m-linux_x86_64.whl
# Mac OS X, CPU only:
(tensorflow)$ pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.8.0rc0-py3-none-any.whl

conda 环境激活后,你可以测试:

$ python
>>> import tensorflow as tf
>>> print(tf.__version__)
# 0.11.0rc0

3、开启或关闭环境
当你不用 TensorFlow 的时候,关闭环境:

(tensorflow)$ source deactivate
$ # Your prompt should change back

再次使用的时候再激活 :

$ source activate tensorflow
(tensorflow)$  # Your prompt should change.
# Run Python programs that use TensorFlow.
...
# When you are done using TensorFlow, deactivate the environment.
(tensorflow)$ source deactivate
