How to disable message "Solving linear variational problem."

Question

It seems whenever we solve a variational problem with "solve", it always gives the message "Solving linear variational problem." Is there any way to disable the message?

Answer 1

Yes, either raise the log level by calling the command

set_log_level(level)

where level is either WARNING or ERROR. You can experiment with different levels to get different amounts of diagnostic messages:

CRITICAL  = 50, // errors that may lead to data corruption and suchlike
ERROR     = 40, // things that go boom
WARNING   = 30, // things that may go boom later
INFO      = 20, // information of general interest
PROGRESS  = 16, // what's happening (broadly)
TRACE     = 13, // what's happening (in detail)
DBG       = 10  // sundry

To turn of logging completely, use

set_log_active(False)
