OOM errors with large example maps

[sdtblck]

Hi,

is there a hard limit to the size of the example image?

Consistently getting Out of memory errors with example images larger than around 300 pixels when testing on google colab

Any help would be appreciated :)

Also getting the following error, not sure if it's the cause of the crash or an effect of it:

`modified output size: (2050, 2050, 3) number of patches: 34
