How do I install shogun's python interface?

I'm on a Mac. Step 1:

sudo conda install -c conda-forge shogun

Step 2:

$ 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
Type "help", "copyright", "credits" or "license" for more information.

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

I also tried on Fedora using the RPMs. After verifying that the C++ interface works (gcc shogun.cpp -I/usr/include/shogun/base -lshogun -L/usr/lib64/libshogun.*) I followed the instructions here and set PYTHONPATH=/usr/lib64/python2.7/site-packages/modshogun.py

And then:

$ 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
Type "help", "copyright", "credits" or "license" for more information.
>>> import shogun
>>> from shogun import RealFeatures, PolyKernel, CSVFile
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name RealFeatures

The problem here is probably that shogun's docs are currently for the in-development version 6.1, but the conda package is for the latest actual release 6.0. In 6.0, you need to do from modshogun import RealFeatures; the shogun package is the old interface, and the modern "modular" one is modshogun. This will be renamed to just shogun in the upcoming 6.1 release.
