ValueError: could not convert string to float: ''

[omegarhovega]

Hi there,

Thanks a lot for sharing! I am getting the following error when executing main.py and the Tkinter window remains black except the buttons are showing:

Deribit_github_test/option-visualiser-main/main.py", line 63, in plot_charts chart_low = float(chart_minprice_input.get()) ValueError: could not convert string to float: ''

Could it be that the variables are initialised empty and the empty string cannot be converted into a float? I tried assigning initial values but the app broke with the same error.

Thankful for any insight!

This error does occur when the 'Plot' button is pressed with nothing entered in the Chart Min Price input (chart_minprice_input). If you type something in there (even 0), then it should work.
I assume you are getting this error when clicking the button?

For reference I am currently running this code successfully in PyCharm Community Edition with Python 3.10.

Thanks, the error occurs when running main.py, the Tkinter window already opens black (only buttons showing). It seems that Plot is run automatically when running the code without waiting for my input - or another issue as the blackened out window is a bit weird.

I also have the same issue when attempting to run your deribit-max-pain script.

I am using VS Code + Python 3.10.

Oh I see. It does sound like it's either running that function automatically, or something is automatically pushing that button. I'm not familiar with VS Code, but my next suggestion would be to try running the code from somewhere else (such as PyCharm (free) as I know it works there). This will help test if it's possibly an issue with how the code runs from VS Code specifically.

I tried running from Mac Terminal with same results, I will try and have a look and replicate with PyCharm. Thanks!

No worries.

Not that I think this is the issue, but it may be worth mentioning that I write and test everything on Windows. I never do any coding or testing on Mac.
