hifir4py.Verbose¶

class Verbose(value)[source]¶

Verbose level

Note

All attributes are bit masks that support bit-wise or

FAC = 4¶

Enable verbose for factorization

Warning

This will slow down the factorization significantly!

INFO = 1¶

General info mask (set by default)

NONE = 0¶

NONE mask, use to disable verbose

PRE = 2¶

Enable verbose information with regards to preprocessing

PRE_TIME = 8¶

Enable timing on preprocessing
