Question

我的keras与theano和GPU配合得很好，但今天早上，我用以下方式升级了keras和theano之后：

pip install git+git://github.com/fchollet/keras.git --upgrade --no-deps
pip install git+git://github.com/Theano/Theano.git --upgrade --no-deps

并运行import theano，它首先引发错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/theano/__init__.py", line 79, in <module>
    from theano.scan_module import (scan, map, reduce, foldl, foldr, clone,
  File "/usr/local/lib/python2.7/dist-packages/theano/scan_module/__init__.py", line 41, in <module>
    from theano.scan_module import scan_opt
  File "/usr/local/lib/python2.7/dist-packages/theano/scan_module/scan_opt.py", line 71, in <module>
    from theano.scan_module import scan_op
  File "/usr/local/lib/python2.7/dist-packages/theano/scan_module/scan_op.py", line 58, in <module>
    from six import iteritems, integer_types, raise_from
ImportError: cannot import name raise_from

然后再次运行import theano，它会引发错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/theano/__init__.py", line 79, in <module>
    from theano.scan_module import (scan, map, reduce, foldl, foldr, clone,

    from theano.scan_module import scan_opt
  File "/usr/local/lib/python2.7/dist-packages/theano/scan_module/scan_opt.py", line 60, in <module>
    from theano import tensor, scalar
ImportError: cannot import name tensor

运行import keras，它首先引发错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/keras/__init__.py", line 2, in <module>
    from . import backend

    from .theano_backend import *
  File "/usr/local/lib/python2.7/dist-packages/keras/backend/theano_backend.py", line 1, in <module>
    import theano
  File "/usr/local/lib/python2.7/dist-packages/theano/__init__.py", line 79, in <module>
    from theano.scan_module import (scan, map, reduce, foldl, foldr, clone,
  File "/usr/local/lib/python2.7/dist-packages/theano/scan_module/__init__.py", line 41, in <module>
    from theano.scan_module import scan_opt
  File "/usr/local/lib/python2.7/dist-packages/theano/scan_module/scan_opt.py", line 71, in <module>
    from theano.scan_module import scan_op
  File "/usr/local/lib/python2.7/dist-packages/theano/scan_module/scan_op.py", line 58, in <module>
    from six import iteritems, integer_types, raise_from
ImportError: cannot import name raise_from

然后再次运行import keras，它会引发错误：

Using Theano backend.
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/keras/__init__.py", line 2, in <module>

    import theano
  File "/usr/local/lib/python2.7/dist-packages/theano/__init__.py", line 79, in <module>
    from theano.scan_module import (scan, map, reduce, foldl, foldr, clone,
  File "/usr/local/lib/python2.7/dist-packages/theano/scan_module/__init__.py", line 41, in <module>
    from theano.scan_module import scan_opt
  File "/usr/local/lib/python2.7/dist-packages/theano/scan_module/scan_opt.py", line 60, in <module>
    from theano import tensor, scalar
ImportError: cannot import name tensor

我真的很困惑这个问题，以前有人遇到过这个问题吗？提前谢谢！

- no-deps， - no-dependencies 忽略包依赖

删除该标志，一切正常
