Cythonizing sklearn/_isotonic.pyx failed

[schumanng]

Hello everybody,

I'm new to GitHub, so please excuse me if I've forgotten any of the usual information.

I'm following the EM_MV example (https://github.com/ngoix/EMMV_benchmarks). Since these methods use the one_class_data, I first wanted to install the OCRF.
I was able to run all the commands of the installation instructions without any problems - except for the last one: python setup.py install

Here I got the following error:

Cython is installed with the latest version:
(OCRF_env) Gerrits-Air:OCRF gerritschumann$ pip install --upgrade Cython

Result: Requirement already up-to-date: Cython in /Users/gerritschumann/anaconda3/envs/OCRF_env/lib/python2.7/site-packages (0.29.13)

To my knowledge, no other Cython versions are installed:
(OCRF_env) Gerrits-Air:OCRF gerritschumann$ python -c "import cython; print(cython.__version__)"

Result: 0.29.13

If relevant: I already had Python 3.6.9 installed on my Macbook. Due to the OCRF installation, I now have Python 2.7. as environment.

If there is no quick fix for the problem, is there any way to reconstruct the output of one_class_data so that I can play through the EM_MV example?

It would really help me a lot! Many Thanks in advance!
