Log File in Gurobi 9?
AnsweredJust updated to Gurobi 9. Was the log file output disabled by default in Gurobi 9?
If so, is there a way to permanently change the parameter responsible to always output a log file by default, as in Gurobi 8?
Thanks!

Hi Ahmad -
Yes, for v9.0 there is a change in the default for creating the logfile; the default log file only exits for gurobi_cl and the interactive shell with v9.0. Otherwise, you need to set the LogFile parameter.

Thanks for the quick reply.
For someone who is used to having the log file outputting by default, setting the parameter each time I run a model is quite cumbersome. Is there a way to change the default value to avoid having to do this every time?

Hi,
I am setting the LogFile parameter manually but the file is almost empty! The only part copied to my logfile is this:Gurobi 9.0.1 (win64) logging started 04/22/20 14:49:32
Changed value of parameter LogFile to gurobi.log
Prev: Default:
Parameter OutputFlag unchanged
Value: 1 Min: 0 Max: 1 Default: 1
Discarded solution informationWould you please tell me what I am doing wrong or what's the correct way to set the LogFile parameter?
Thanks.

Hi Vincent,
Make sure to put it before the "optimize" method.
