Display LP filename instead of "Model fingerprint".
I just upgraded to Gurobi 9.0.0 from 8.1.1. In Gurobi 8.1.1, my gurobi.log dispalyed something like:
Gurobi 8.1.1 (win64, Python) logging started 11/09/19 16:05:03
Academic license - for non-commercial use only
Read LP format model from file C:\Users\ME\Desktop\Gurobi_LP_Models\Group2_c_1.lp
Reading time = 0.00 seconds
....and so on.
In Gurobi 9, the log file was disabled by default (it seems) so after enabling it and get the following log file:
Gurobi 9.0.0 (win64) logging started 12/01/19 21:18:20
Changed value of parameter LogFile to GurobiLog9.log
Prev: Default:
Changed value of parameter NodefileStart to 0.5
Prev: inf Min: 0.0 Max: inf Default: inf
Changed value of parameter TimeLimit to 36000.0
Prev: inf Min: 0.0 Max: inf Default: inf
Gurobi Optimizer version 9.0.0 build v9.0.0rc2 (win64)
Optimize a model with 35 rows, 13 columns and 107 nonzeros
Model fingerprint: 0x2dc75c86
...and so on.
For my purposes, it is useful to see the LP file that is read as opposed to the "Model fingerprint". Is it possible to display that in Gurobi 9?
Note that in Gurobi 9, the log that is displayed to the console (in Python) is identical to what is displayed in Gurobi 8's logfile above. This is what I would like Gurobi 9's logfile to display as well.
