Output concrete model like the pprint() format

[wt00...@gmail.com]

Dear All,

I would like to know if there is any way to output a concrete model with the format like pprint() function.

I know that I could use write() function to output the model as a LP file. However,  the generated format does not contribute to debug too much. Instead, pprint() function provides a pretty beautiful and clear way to display the model, which help the debugging a lot. How could I save the results in a text file?

Thank you very much.

This doesn’t quite answer your question, however, I do the following very often.

 

I put “m.pprint()” in my Python script and then from the terminal:

 

• Python mycode.py &> output.txt

 

Then the output is stored in output.txt. This is not a Pyomo command, but a bash shell capability. There may be other ways to capture the pprint output in Python.

 

Regards,

 

Carl.

pprint() takes an ostream argument:

 

with open('output.txt', 'w') as FILE:

    model.pprint(ostream=FILE)

Hi John,

Thank you very much. Your method works.

It seems that writing the file is a little time-consuming. May I ask do you have any other better methods to debug a concrete model?

Best regards,

Tao Wu
