while I was trying to install csc-pyparse I got this error
pysparse/sparse/src/spmatrixmodule.c:1:20: fatal error: Python.h: No such file or directory
so it seems that csc-pyparse couldn't be installed for newer versions of python (python 3) check here
so could you port python-recsys to SciPy as an alternative or solve this problem please :/ .
