为 TensorFlow 安装 prettytensor 无法在 OSX 上运行

Question

我无法安装prettytensor。我已经尝试通过pip 以及通过安装源代码并在目录中执行python setup.py install 来实现它。

我更新了我的 tensorflow 。有没有人知道如何在我的机器上安装prettytensor？

pip install prettytensor
Requirement already satisfied (use --upgrade to upgrade): prettytensor in ./anaconda/lib/python2.7/site-packages/prettytensor-0.6.0-py2.7.egg
Requirement already satisfied (use --upgrade to upgrade): enum34>=1.0.0 in ./anaconda/lib/python2.7/site-packages (from prettytensor)
Requirement already satisfied (use --upgrade to upgrade): six>=1.10.0 in ./anaconda/lib/python2.7/site-packages (from prettytensor)
Collecting tensorflow>=0.7.1 (from prettytensor)
  Could not find a version that satisfies the requirement tensorflow>=0.7.1 (from prettytensor) (from versions: )
No matching distribution found for tensorflow>=0.7.1 (from prettytensor)

当我尝试导入 prettytensor

请检查 tensorflow 的版本。

如果你的 tensorflow 不是 0.7.1，你可以像下面这样升级。

（另见https://www.tensorflow.org/versions/r0.7/get_started/os_setup.html）

# Mac OSX, CPU only:
$ pip install --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.7.1-cp27-none-any.whl

然后再次安装 prettytensor。

$ pip uninstall prettytensor
$ pip install prettytensor

供您参考。 这是我的结果。（OSX 10.11.3）

In [1]: import tensorflow as tf

In [2]: tf.__version__
Out[2]: '0.7.1'

In [3]: import prettytensor as pt

In [4]: pt.PrettyTensor
Out[4]: prettytensor.pretty_tensor_class.PrettyTensor
