"Fortran runtime error" with example_05.py #144

Closed kercc1985 closed 2 years ago

kercc1985 commented 2 years ago

Hi, Experts: I am currently learning Rosco, I think I have installed Rosco successfully and run the example in 'standard_use. RST', the 4 examples from 01-04 are running with no problem, but when running 'example_05.py' I get an error like this:

I do not have any clue about this mistake, I hope you can help me find out what is the reason. Thanks.

This error is generated because ROSCO can't find your input file. It seems to think that 'D:\z各种资料\小工具汇总\ROSCO-main2022-2.5.0\ROSCO-main' is the input file, which looks like a directory. I'm not sure why it's set this way, since the input file is defined here.

I have heard that there are issues with this example on Windows, so perhaps you might skip it. Otherwise, we need to figure out why the filename is truncated. This is the file that sets up the control interface in python.

Is the input file referred to by this error the 'libdiscon.dll' file?
I find that 'lib_name' is the input to the 'ControllerInterface' module. lib_name is given here: lib_name= os.path.join(this_dir, '../ROSCO/build/libdiscon.dll')

Truncating the string of a path is indeed an odd situation. I'll try a little more and see if I can find out the reason.

dzalkind commented 2 years ago

I think the issue is with param_file, perhaps around here

kercc1985 commented 2 years ago

dear dzalkind, You're right. The issue is with self.accINFILE = self.param_name.encode('utf-8'). When I remove the Chinese path from the project path, the program runs well, although it's not the fundamental solution to the issue. Thank you again.
