ValueError: Image size of 8804752x396 pixels is too large. It must be less than 2^16 in each direction.

Answer 1

I think the error code is very clear: the image you are trying to plot is way to big. You have to reduce the size of the image, ie you have to scale it down. What are you even trying to plot which has a size of 8804752x396 ? Are you sure, that you did nothing wrong before? This seems to be very huge.

Edit: If you just want to save the image as a png or something like this, you try to change the backend to something else - look here for better suited backends for your task and try them!
