WebI don't see what the advantages of csr format are in this case. Sure, all the nonzero values are collected in one .data array, with the corresponding column indexes in .indices.But … WebSciPy API# Importing from SciPy# In Python, the distinction between what is the public API of a library and what are private implementation details is not always clear. Unlike in other languages like Java, it is possible in Python to access “private” functions or objects. Occasionally this may be convenient, but be aware that if you do so ...
