The Makefile provided in the examples/build directory of the Gurobi installation is not intended as a template for building a production application. Rather, it is intended as a way to compile and ...

Hi Ying, Thanks for reporting this. I agree with you that this is not the right behaviour, really any `nan` values in input data should result in an error when building a model. Evidently there is ...

Hi all, sorry for the delayed follow-up. Is everyone experiencing this issue using numpy in some way? If anyone has a minimal working example where the memory issue occurs and numpy is *not* involv...

Hi Samuel, gurobipy is tightly integrated with the Gurobi C API, so C code is called any time you make a gurobipy API call. For example: gp.Model(...) calls the C API to construct a model x = mode...

Hi Artem, The syntax of a generator expression in Python is defined here: https://docs.python.org/3/reference/expressions.html#generator-expressions. It's syntactically very similar to a list compr...

Hi Artem, I discovered that `model.addConstrs` does introspection on the provided generator frame. Indeed it does. This is really the only way to pull off this particular bit of magic; as you cor...

This deprecation warning comes from newer versions of numpy, please see https://support.gurobi.com/hc/en-us/articles/16534198159889 for further information. Your code in the screenshot looks correc...

Hi Richard, Currently, transpose is only implemented for MVars, not the corresponding expression objects (MLinExpr and MQuadExpr). You can work around it in this case by expanding out the transpose...

Adding some extra detail here since this question comes up from time to time. The short answer is this: The usual simple tricks for parallelizing Python code do not work for the term-based modelin...

Hi Saeid, If you are looking for a mapping in your model based on this dictionary, i.e. if x = 1 then y = 2, if x = 3 then y = 4, etc, then yes, you would need to introduce binary variables which e...
