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。括号中的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。）我也尝试通过pip卸载并重新安装Theano但仍然得到相同的错误。有什么建议吗？

以下是上下文：

(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()).

Answer 1

我遇到了同样的问题。

手动删除缓存。

rm -rf ~/.theano

如果这样做无助于尝试从源代码安装。

python setup.py install

Theano ImportError：无法导入名称inplace_increment
