How do I resolve an "Model too large for size-limited Gurobi license" error?

The error message "Model too large for size-limited Gurobi license" or "Model too large for restricted Gurobi license" is displayed when Gurobi uses a restricted, size-limited license, and the model size exceeds these limits, i.e., 2000 variables, 2000 linear constraints, and 200 quadratic constraints.

This error typically occurs when Gurobi is installed using the pip package distributor. The pip installation process automatically includes a size-limited license.
