mac安装tensorflow遇到问题

tensflow安装参考(http://www.tensorfly.cn/tfdoc/get_started/os_setup.html)
执行如下：

pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl

出现如下问题：

Installing collected packages: numpy, six, tensorflow
  Found existing installation: numpy 1.8.0rc1
    DEPRECATION: Uninstalling a distutils installed project (numpy) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
    Uninstalling numpy-1.8.0rc1:

You are using pip version 9.0.1, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

接下来先升级pip

pip install --upgrade pip

重新执行安装命令

pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl

出现如下问题：

matplotlib 1.3.1 requires nose, which is not installed.
matplotlib 1.3.1 requires tornado, which is not installed.

Cannot uninstall 'numpy'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
Installing collected packages: six, tensorflow
  Found existing installation: six 1.4.1
Cannot uninstall 'six'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

看到出现了2个问题，其中一个是nose，tornado没有安装，第三个是不能安装numpy，six，因为存在旧的版本。
从而执行如下解决:

pip install nose
pip install tornado
pip install numpy --upgrade --ignore-installed
pip install six --upgrade --ignore-installed

最后再次执行安装成功：
