Hi Daniel,

I noticed that the export_as_lp() is not exporting the lp file.

i wrote ;

mdl = Model("LP")

mdl.export_as_lp("C:\input files\sample data\rps.lp")

its not generating the lp file in the path.

I even tried with backslash like mdl.export_as_lp("C:/input files/sample data/rps.lp")

am I misssing something here?

All the arguments you passed to the function look like they do not represent the file names you have in mind.

"C:\input files\sample data\rps.lp" will use the special characters '\i', '\s', and '\r', you will have to escape the backslashes in case you you have backslashes in string arguments.

"C:/input files/sample data/rps.lp" does not look like a valid file system path.

Can you try any of this:

mdl.export_as_lp(r"C:\input files\sample data\rps.lp")
mdl.export_as_lp("C:\\input files\\sample data\\rps.lp")
