getting error while running my modflow model

[zargol7419]

Hi,
I am using flopy package to execute my existing model using run_model code, but when it comes to running the model I've got this error, and I don't know what is the problem. Could you please help me in this regard? I really appreciate your answers.
Here is the executed code:

The reason that it is crashing is that your call signiture is incorrect. From the run_model documentation:

exe_name : str
        Executable name (with path, if necessary) to run.
namefile : str
        Namefile of model to run. The namefile must be the
        filename of the namefile without the path. Namefile can be None
        to allow programs that do not require a control file (name file)
        to be passed as a command line argument.
model_ws : str
        Path to the location of the namefile. (default is the
        current working directory - './')

psuedocode example:

success, buff = flopy.run_model(
    namefile="mynamefile.nam", 
    exe_name="path/to/my/modflow.exe", 
    model_ws="path/to/the/directory/that/contains/my/namefile"
)
