Unable to import Tensorflow "No module named copyreg"
提问by Minh Mai
El Capitan OS here. I've been trying to find a workaround with import Tensorflow into my ipython notebook, but so far no luck.
El Capitan 操作系统在这里。我一直试图找到一种将 Tensorflow 导入到我的 ipython 笔记本中的解决方法，但到目前为止还没有运气。
Like many people in the forums, I've also had issues with install tensorflow because of the six package. I was able to install after some fidgeting with brew
像论坛中的许多人一样，由于六个包，我也遇到了安装 tensorflow 的问题。在对 brew 进行一些坐立不安之后，我能够安装
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
I got a message that tensorflow was installed correctly. Even when I did sudo pip install tensorflowI get the message:
我收到一条消息，表明 tensorflow 已正确安装。即使sudo pip install tensorflow我收到了消息：
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)
However, when I'm on my ipython notebook and I did an import tensorflowI get the message: ImportError: No module named tensorflow
但是，当我在 ipython 笔记本上执行操作时，import tensorflow我收到消息：ImportError: No module named tensorflow
I've dug further and found this error on the import as well:
我进一步挖掘并在导入中发现了这个错误：

As Jonah commented, it's solved by this:
正如约拿所评论的那样，它已通过以下方式解决：
On MacOSX
在 MacOSX 上
If you encounter:
如果您遇到：
import six.moves.copyreg as copyreg
ImportError: No module named copyreg
Solution: TensorFlow depends on protobuf which requires six-1.10.0. Apple's default python environment has six-1.4.1 and may be difficult to upgrade. So we recommend either installing a separate copy of python via homebrew:
解决方案：TensorFlow 依赖于需要 6-1.10.0 的 protobuf。苹果默认的python环境有6-1.4.1，可能很难升级。因此，我们建议通过自制软件安装单独的 python 副本：
brew install python
But I highly recommend using virtualenv for this purpose.
但我强烈建议为此目的使用 virtualenv。
# On Mac:
$ sudo easy_install pip # If pip is not already installed
$ sudo pip install --upgrade virtualenv
Next, set up a new virtualenv environment. To set it up in the directory ~/tensorflow, run:
接下来，设置一个新的 virtualenv 环境。要在目录中设置它~/tensorflow，请运行：
$ virtualenv --system-site-packages ~/tensorflow
$ cd ~/tensorflow
Then activate the virtualenv:
然后激活virtualenv：
$ source bin/activate # If using bash
$ source bin/activate.csh # If using csh
(tensorflow)$ # Your prompt should change
Inside the virtualenv, install TensorFlow:
在 virtualenv 中，安装 TensorFlow：
(tensorflow)$ pip install --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl
You can then run your TensorFlow program like:
然后你可以像下面这样运行你的 TensorFlow 程序：
(tensorflow)$ python tensorflow/models/image/mnist/convolutional.py
# When you are done using TensorFlow:
(tensorflow)$ deactivate # Deactivate the virtualenv
$ # Your prompt should change back

Copyreg can be found in the six module in Python2.
Copyreg 可以在 Python2 的六个模块中找到。
Short answer, try upgrading/installing six:
简短回答，尝试升级/安装六个：
pip install -U six
回答by Russell
Maybe try reinstalling six. It looks like it is in a different location from your other libraries. /Library/Python/...vs /usr/local/lib/...This probably means that six was install before homebrew python.
也许尝试重新安装六个。它看起来与您的其他库位于不同的位置。/Library/Python/...vs/usr/local/lib/...这可能意味着在自制 python 之前安装了六个。

Another simple way I tried to fix this is to edit the source code and python_message.pyand change the line import six.moves.copyreg as copyreginto from six.moves import copyreg.
我尝试解决此问题的另一种简单方法是编辑源代码并将python_message.py该行更改import six.moves.copyreg as copyreg为from six.moves import copyreg.
Of course you might need to change the permission of this read-only file in order to modify it.
当然，您可能需要更改此只读文件的权限才能对其进行修改。
