Ran my model and received this response:

Optimize a model with 100 rows, 7500 columns and 52500 nonzeros
Model fingerprint: 0x862fc4f5
Model has 3750 general constraints
Variable types: 7500 continuous, 0 integer (0 binary)
Coefficient statistics:
Matrix range [2e-01, 1e+00]
Objective range [1e+00, 1e+00]
Bounds range [0e+00, 0e+00]
RHS range [5e+01, 6e+03]
Presolve removed 100 rows and 3750 columns
Presolve time: 0.00s

Explored 0 nodes (0 simplex iterations) in 0.00 seconds
Thread count was 1 (of 8 available processors)

Solution count 0

Best objective -, best bound -, gap -
Traceback (most recent call last):
File "final_project.py", line 101, in <module>
m.optimize()
File "model.pxi", line 833, in gurobipy.Model.optimize
gurobipy.GurobiError: Empty general constraint with infinite constant

 

Please let me know what other information I can provide?

I don't know of any infinite values in my model, nor of any empty general constraints.

 

Thanks

Sam
