There could be various reasons why Pyomo's write function fails to produce the ".nl" output. These could be:
Incorrect model formulation: The Pyomo model may have been incorrectly formulated with constraints or objective functions that are not consistent or feasible. This may result in the solver failing to generate the ".nl" output.
Missing solver files: The solver files required to generate the ".nl" output may be missing. These files are necessary for the conversion of the Pyomo model into the solver's native format, and without them, the write function will not be able to produce the output file.
Solver compatibility issues: The Pyomo model may have been formulated using a solver that is not compatible with the write function. In such cases, it may be necessary to switch to a different solver or update the solver files.
Insufficient memory or storage space: The write function may fail if there is insufficient memory or storage space available on the computer. This may result in the Pyomo model not being properly loaded or processed, leading to the failure of the write function.
To resolve these issues, it is important to review the model formulation, ensure that all required solver files are present, and verify that the selected solver is compatible with the Pyomo model. Additionally, ensuring that there is sufficient memory and storage space available may also help resolve the issue.
