python-2.7 - Theano导入错误: cannot import name 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

我在 Python 2.7 中使用 conda。括号里的python2是我的conda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。

我收到的错误是 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)，但仍然出现相同的错误。 (我不能使用 theano-cache purge 因为它需要安装与 OpenCV 所需版本冲突的 scipy 版本。)我还尝试通过 pip 卸载并重新安装 Theano，但仍然得到同样的错误。有什么建议吗？

这里是上下文:

(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__

我遇到了同样的问题。

手动删除缓存有效。

rm -rf ~/.theano

如果这没有帮助，请尝试从源安装。

python setup.py install
