Load model from txt file

[Alberto Manzini]

Hi everyone, I've saved my model in a txt file using method

model.ExportToFile(filename)

I don't understand how to load back my model from this file. I assume I have to load the proto message from file and setting it to a (empty) model, but I'm looking for the exact python commands to follow

Thanks for any help

There are no api. This is used mostly for debugging purposes.

from ortools.sat.python import cp_model
from google.protobuf import text_format

model = cp_model.CpModel()
with open("model.txt", "r") as file:
    text_format.Parse(file.read(), model.Proto())

Cool, many thanks!

The question is to recover solutions.

You can use model.Get{Int|Bool|Interval}VarFromProtoIndex to rebuild variables to use to recover solutions.

Hi, I was looking for a method to export and load the model, not the solutions, to debug it

Thank you both
