来自源主服务器的Tensorflow会从导入中产生语法错误(Tensorflow from source master gives a syntax error from import)

我尝试从源代码（master）编译tensorflow，并遵循使用python3而不是python2的张量传递指令（并且pip默认为pip3 ）。在测试第一个模型之前，我可以完成所有步骤。

我注意到，通过做一个简单的import tensorflow可以最小程度地复制问题。错误如下：

与类似语法问题相关的其他问题与旧版本的protobuf ，但我的版本是3

$ pip3 show protobuf --- Metadata-Version: 2.0 Name: protobuf Version: 3.0.0b2 Summary: Protocol Buffers Home-page: https://developers.google.com/protocol-buffers/ Author: protobuf@googlegroups.com Author-email: protobuf@googlegroups.com Installer: pip License: New BSD License Location: /usr/local/lib/python3.5/dist-packages Requires: six, setuptools Classifiers: Programming Language :: Python Programming Language :: Python :: 2 Programming Language :: Python :: 2.6 Programming Language :: Python :: 2.7 Programming Language :: Python :: 3 Programming Language :: Python :: 3.3 Programming Language :: Python :: 3.4

我怎么解决这个问题？

I tried compiling tensorflow from sources (master) and follow the tensorflow instructions using python3 instead of python2 (and pip defaults to pip3). I can achieve all steps until testing the first model.

I noticed that the problem can be minimally reproduced by doing a simple import tensorflow. The error is as follows:

Other questions related to similar syntax problems are related to older versions of protobuf, however my version is 3

How can I solve this problem?

最满意答案

它看起来像已安装的dateutil包（TensorFlow依赖于dask和pandas ）与Python 3不兼容，使用反引号作为repr()的同义词，在3.0中删除了它。 2011年为Python 3更新了发生错误的dateutil/parser.py中的特定行。

尝试运行以下命令来升级dateutil ：

$ pip3 install python-dateutil --upgrade

It looks like the installed dateutil package (which TensorFlow depends on via dask and pandas) is incompatible with Python 3, using backticks as a synonym for repr(), which was removed in 3.0. The particular line from dateutil/parser.py where the error occurs was updated for Python 3 in 2011.

Try running the following command to upgrade dateutil:

$ pip3 install python-dateutil --upgrade
