python - Tuning multiple Gurobi models at once - Stack Overflow

i want to tune the hyper parameters of Gurobi for several optimization problems at once. I have a folder with several .lp files.

At the moment i am using this code to tune one model in Python:

model = gp.read("model.lp")
model.tune()

But this code only works for one instance of my problem. I want to tune several problem instances at once. Thanks!

• You'll need to edit your question to show the full code of how you are iterating over the models – AirSquid Commented Jan 6 at 20:01
• Try to use mps files instead of lp files. You lose accuracy with lp files. – Riley Commented Jan 9 at 6:47

This is possible, but only via the command line tool grbtune
