如何安装幕府的python界面？

Question

我用的是Mac电脑。步骤1：

sudo conda install -c conda-forge shogun

第2步：

$ python
Python 2.7.12 |Anaconda custom (x86_64)| (default, Jul  2 2016, 17:43:17)
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)] on darwin

>>> import shogun
>>> from shogun import RealFeatures, PolyKernel, CSVFile
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name RealFeatures

我还使用RPM在Fedora上进行了尝试。在验证C++接口(gcc shogun.cpp -I/usr/include/shogun/base -lshogun -L/usr/lib64/libshogun.*)正常工作后，我按照here和set PYTHONPATH=/usr/lib64/python2.7/site-packages/modshogun.py的说明进行操作

然后：

$ python
Python 2.7.13 (default, May 10 2017, 20:04:36)
[GCC 6.3.1 20161221 (Red Hat 6.3.1-1)] on linux2

>>> import shogun
>>> from shogun import RealFeatures, PolyKernel, CSVFile
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name RealFeatures

Answer 1

这里的问题可能是，幕府的文档目前是针对正在开发的6.1版本，但conda包是针对最新的实际版本6.0。在6.0中，您需要执行from modshogun import RealFeatures；shogun包是旧的接口，而现代的“模块化”包是modshogun。在即将发布的6.1版本中，它将被重命名为shogun。
