无法导入Tensorflow"没有名为copyreg的模块"

Question

El Capitan OS在这里.我一直试图找到一个解决方法,导入Tensorflow到我的ipython笔记本,但到目前为止没有运气.

像论坛中的很多人一样,由于六个包,我也遇到了安装张量流问题.我可以在使用brew进行一些烦躁之后安装

brew link gdbm
brew install python
rew linkapps python
sudo pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl

我收到一条消息,表明tensorflow已正确安装.即使我这样做,sudo pip install tensorflow我收到的消息:

Requirement already satisfied (use --upgrade to upgrade): tensorflow in /usr/local/lib/python2.7/site-packages
Requirement already satisfied (use --upgrade to upgrade): six>=1.10.0 in /Library/Python/2.7/site-packages (from tensorflow)
Requirement already satisfied (use --upgrade to upgrade): numpy>=1.9.2 in /usr/local/lib/python2.7/site-packages (from tensorflow)

但是,当我在我的ipython笔记本上并且我做了一个时,import tensorflow我收到了消息:ImportError: No module named tensorflow

我进一步挖了并在导入时发现了这个错误:

ImportError: No module named copyreg

Answer 1

正如乔纳评论的那样,它解决了这个问题:

在MacOSX上

如果遇到:

import six.moves.copyreg as copyreg

ImportError: No module named copyreg

解决方案:TensorFlow依赖于protobuf,需要6-1.10.0.Apple的默认python环境有6个1.4.1,可能很难升级.所以我们建议通过自制软件安装一个单独的python副本:

brew install python

但我强烈建议将virtualenv用于此目的.

# On Mac:
$ sudo easy_install pip  # If pip is not already installed
$ sudo pip install --upgrade virtualenv

接下来,建立一个新的virtualenv环境.要在目录中进行设置~/tensorflow,请运行:

$ virtualenv --system-site-packages ~/tensorflow
$ cd ~/tensorflow

然后激活virtualenv:

$ source bin/activate  # If using bash
$ source bin/activate.csh  # If using csh
(tensorflow)$  # Your prompt should change

在virtualenv中,安装TensorFlow:

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

然后,您可以运行TensorFlow程序,如:

(tensorflow)$ python tensorflow/models/image/mnist/convolutional.py

# When you are done using TensorFlow:
(tensorflow)$ deactivate  # Deactivate the virtualenv

$  # Your prompt should change back
