When I run main.py an exception occurs:

SyntaxError: unexpected EOF while parsing

There's something wrong with the line gui = GUI(2000, 2000) Or I didn't install the libraries correctly.

I didn't change the code. It worked before. I use Windows and Conda

What is wrong with:

        Path(user_config_dir('flowtutor')).mkdir(parents=True, exist_ok=True)
        with dbm.open(join(user_config_dir('flowtutor'), 'settings.db'), 'c') as db:
            if key not in db:
                return default
            else:
                val = db[key].decode()
                return val if val else default

There was an error running FlowTutor with Python 3.12, becase of an incompatible dependency. I fixed this issue in version 0.11.0

The second problem seems to be associated with the file, where the settings are stored. Could you try running FlowTutor in a fresh virtual environment?

DmitryKaverznev commented 5 months ago

Thanks for the answer, here are the steps I take:

  1. Create a virtual environment conda (3.12)
  2. Install packages (python -m pip install flowtutor)
  3. Run main.py (src\flowtutor)
  4. I get the error:

SyntaxError: invalid syntax


The Traceback shows that something is wrong in the gui class. It is not very different from the previous one, the interpreter does not like it:
     self.parent_size = (int(self.settings_service.get_setting('width', '1000') or 1000),
                         int(self.settings_service.get_setting('height', '1000') or 1000))

Maybe it's the new packages?

Thanks for the feedback.

If you install it with conda like your step 2, there should be an exe somewhere. I installed conda on my system to try it out and for me it was located at C:\Users\User\AppData\Roaming\Python\Python312\Scripts\flowtutor.exe Depending on your setup, it might get installed to a location in your PATH. In that case you can just run it directly from the terminal with the command "flowtutor".

You shouldn't have to manually run main.py in either case.

From the error message I think maybe the file where the settings are stored got corrupted on your system somehow. There should be a directory C:\Users\User\AppData\Local\flowtutor\flowtutor which contains a few files. Could you try deleting everything from this directory and see if that helps?

Thank you, I realized that there is no need to rebuild the application and run main.py. Now there is an application for visualizing algorithms
