I can reproduce that for current master branch.

Problems are in findContours, it's working for different settings?

No I tried different setting and not working. Maybe my input is not good to find contour?

enzyme69 commented 5 years ago

Still no output and getting red with simple image... wonder why.

My guess that it might be missing module or something additional?

feler404 commented 5 years ago

I reproduce your problem but not for 'uint8' DType image. So try to use TypeConver node and switch type to 'uint8'.

If still don't work please send me logs.
