I am re-posting this question as it was closed.
However, How to add static(html, css, js) files in pyinstaller to create standalone exe file? is NOT a question identical to mine, as my GUI does not make use of any other types of files other then a .py file(code provided below). requests_html is just an imported module.
When I try to compile a simple GUI the compiled .exe file would open an empty command window for a few seconds and shuts down automatically.
I've tried using --hidden-import=sip and anything else I could find online but cannot get it working or figure out why it isn't working properly.
Since, I cannot get any error messages, I include the GUI code below.
Thanks in advance!
