Hi, I need to know how to print (view) the constraints. I generate them with addConstrs(). thanks!

  Hi,

  There is no built-in print function for Gurobi objects. Thus, you can only print the actual expression by rebuilding it on your own by using functions for a linear expression to get the coefficients and variables of the left-hand side and the attributes of linear constraints to get the sense and the right-hand side.

  A different and the most convenient way would be to use the write() function to write an LP file and subsequently work with this LP file.

  Best regards,
  Gwyneth

  you can write the model, then print the written model (possibly in rlp or lp format) in Jupyter Lab (or whatever IDE you are using)
