导入theano:AttributeError:'module'对象没有属性'find_graphviz'

Question

当我import theano在Python中运行时,我收到以下错误消息:

Python 2.7.6 (default, Jun 22 2015, 17:58:13)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import theano
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/theano/__init__.py", line 74, in <module>
    from theano.printing import pprint, pp
  File "/usr/local/lib/python2.7/dist-packages/theano/printing.py", line 35, in <module>
    if pd.find_graphviz():
AttributeError: 'module' object has no attribute 'find_graphviz'

可能是什么问题,以及如何解决它？

我在Ubuntu 14.04.4 LTS x64和Python 2.7.6 x64上使用Theano 0.8.2.

我没试成功:

• sudo apt-get install -y graphviz libgraphviz-dev

Answer 1

在pydot1.2.x版本中,find_graphviz函数已被弃用.要解决此问题,您应该在此处安装pydot 1.1.0版本https://github.com/erocarrera/pydot/tree/v1.1.0.它对我有用.可能有帮助.
