'tupledict' object is not callable
AnsweredI run gurobi via pyhton. I encountered 'tupledict' object is not callable error. Details are given below. I made the line of code which caused error bold.
runfile('C:/gurobi1000/win64/examples/python/production_transportation.py', wdir='C:/gurobi1000/win64/examples/python')
Restricted license - for non-production use only - expires 2024-10-28
Traceback (most recent call last):
File "C:\gurobi1000\win64\examples\python\production_transportation.py", line 202, in <module>
m.addConstrs(
File "src\gurobipy\model.pxi", line 3747, in gurobipy.Model.addConstrs
File "C:\gurobi1000\win64\examples\python\production_transportation.py", line 203, in <genexpr>
(production(i,j,k)==UPH(i,j)*base_prod(i,k) for i in plants for j in prod_line for k in months),"production_assignment_to_lines" )
TypeError: 'tupledict' object is not callable

Hi Furkan,
Please note that this is not a minimal reproducible example and the help that can be provided is only limited.
It is not clear which objects are your variables. I will assume that all 3 objects \(\texttt{production, UPH, base_prod}\) are optimization variables. As described in the documentation of tupledict
To access the members of a
tupledict, you can use standard dict indexing. For example,d[1,2]returns the value associated with tuple(1,2).Thus, your constraint should read
m.addConstrs(production[i,j,k]==UPH[i,j]*base_prod[i,k]
for i in plants for j in prod_line for k in months),
name="production_assignment_to_lines")Best regards,

Thank you Jaromil. I will create a minimal reproducible example for future questions.
Best regards,
