Theano ImportError:无法导入名称inplace_increment

Question

我已经安装了Theano:

(python2) bash-3.2$ sudo pip install --upgrade --no-deps git+git://github.com/Theano/Theano.git

我正在使用Python 2.7的conda.在python2括号内是我的畅达环境.我正在尝试从iGAN运行代码:https://github.com/junyanz/iGAN.我在OS X 10.11.6上.

我得到的错误是ImportError: cannot import name inplace_increment.我已经尝试手动删除Theano缓存(如https://github.com/Theano/Theano/issues/5564中所述)并且仍然出现相同的错误.(我无法使用,theano-cache purge因为它需要安装与OpenCV所需版本冲突的scipy版本.)我也尝试通过pip卸载并重新安装Theano仍然得到相同的错误.有什么建议？

这是上下文:

(python2) bash-3.2$ python iGAN_main.py 
//anaconda/envs/python2/lib/python2.7/site-packages/numpy/lib/utils.py:254: FutureWarning: Numpy has detected that you (may be) writing to an array returned
by numpy.diagonal or by selecting multiple fields in a record
array. This code will likely break in the next numpy release --
see numpy.diagonal or arrays.indexing reference docs for details.
The quick fix is to make an explicit copy (e.g., do
arr.diagonal().copy() or arr[['f0','f1']].copy()).
  ai = a.__array_interface__

我有同样的问题.

手动删除缓存工作.

rm -rf ~/.theano

如果这没有帮助尝试从源安装.

python setup.py install
