KeyError: 'back' while passing the command 'gui' in CLI

[VaishnaviGanamukkala]

I just started to work on visma, and I have an issue while trying to initiate the GUI.

What have I done

I ran the main.py, and was prompted to the CLI. Tried giving the command 'gui'.

Outcome

I received the following error

Log file record

2019-06-26 06:35 - main - INFO: Initialising VisMa...(currently in CLI mode)
2019-06-26 06:35 - window-gui - INFO: Starting VisMa GUI...
2019-06-26 06:35 - window-gui - INFO: Existing VisMa...

Expected Outcome

Visma GUI window must open.

Other ways I tried

• Tried to initiate GUI from python interpreter after installing visma using pip3 install visualmath.
• Tried on virtual environment (venv) and without virtual environment.
• Tried running main.py from the clone of the repository, version 0.2.2, and source zip.
• Tried running the main.py from source zip in 2 other machines.

I think I'm on the wrong track somewhere and I can't proceed any further because of this. Can someone please look into this and help me out?

Hi @VaishnaviGanamukkala!

I tried it in my local system if I am not wrong, there is not an issue in opening the GUI window. Please make sure you have installed all dependencies which can be done with command ./run install (for other arguments with you can type ./run in a terminal and get the list of all other commands available). Please let me know if this works.

Thanks for the reply.
I tried as you mentioned above. But I'm still facing the same problem
I ran pip3 freeze to check all the available packages.

May I know the exact versions of each dependency package, that you are using?
