Manoj Kumar commented on SPARK-6577:
------------------------------------
Ah, I just noticed that SciPy is an optional dependency. In any case, I believe
in that any case having a "if _have_scipy", "else" clause, would lead to more
lines of code to maintain. We could either have SciPy has a hard dependency,
which would mean SparseMatrix would be a wrapper to scipy.CSR routines or we
could just implement our own methods.
> SparseMatrix should be supported in PySpark
