[SciPy-User] check_format in sparse matrix creation

[Gabriel Dulac-Arnold]

Is there a good reason that check_format cannot be disabled when 
creating sparse arrays in scipy.sparse?  If the correct ndarrays are 
provided in the constructor, a lot of what check_format does (pruning, 
typecasting to native byteorder) is not necessary, and wastes a lot of 
time in situations where sparse arrays are being generated in large 
numbers.  Has this been considered / was there a good reason not to 
allow disabling it?

Thanks,

Gabe
