I didn't understand that

Forgive me if this is off topic; I haven't been following this closely
and I haven't used scipy.sparse. But there are some very reasonable
cases where you might want to fill sparse data with a value other than
0:
* The sparseness is missing data, and 0 is not the same as NA
* Better compression:

I'm also OK with these changes. Since we have not established a
versioning or compatibility policy with regards to "Other" data
structures like Tensor and SparseTensor, I don't know that a vote is
needed, just a pull request.

I'd be interested to help with (Python) part of this SparseCSCIndex.
I’d appreciate any comments or suggestions.

Hi,
This sounds fine on the principle. I'll let other comment on the details.

Hi,
I’d like to propose the following improvement of the sparse tensor
format and implementation.
(1) To make variable bit-width indices available.
The main purpose of the first part of the proposal is making 32-bit
indices available. It allows us to serialize scipy.sparse.csr_matrix
objects
