Hi,
The easiest way to read a file is to give the complete path of this file. We provide a copy of afiro.mps in your Gurobi installation directory in examples/data. If you don't want to provide the complete path you should copy the file to your current working directory.
Best regards,
Sonja

You are trying to read a model with
model = read("C:\gurobi902\win64\examples\data\afiro.mps")In Python, \( \texttt{\a} \) is an escape sequence for a special ASCII character. To ensure your path is parsed correctly, try escaping the backslashes in the string with two backslashes:
model = read("C:\\gurobi902\\win64\\examples\\data\\afiro.mps")You could alternatively use \( \texttt{os.path.join()} \) to avoid issues like this.
