I have an app that runs fine in local host but when deploying I get error message

Thanks for the help!
Same here. I am able to use pyautogui to print screenshot in my localhost but it doesn’t work in the streamlit app. Looks like streamlit is not accepting the pyautogui module.
Is there any other ways I can add a screenshot button in streamlit, since a report function hasn’t been developed yet?
Same problem… any suggestion?
I don’t think you can use pyautogui in a headless environment. What would be the point anyway?
I am trying to control the mouse on the screen. Locally is working OK.
That is the problem, when you deploy to streamlit cloud your python code runs in a virtual machine with no mouse and no screen.
Uhn… there is a way to pass the control to browser?
This is programming, there is a way to almost everything. But I don’t know what it can be. Certainly not as easy as just using pyautogui.
