cc3d.dust fails

[doiko]

Working in Ubuntu 22.04 python 3.8 connected-components-3d==3.10.2 numpy==1.23.2

Trying

labels_out = cc3d.dust(
            source_cube[i_range, x_range, s_slice], threshold=100,
            connectivity=26, in_place=False
        )

results to error

    labels_out = cc3d.dust(
  File "cc3d.pyx", line 1070, in cc3d.dust
  File "cc3d.pyx", line 969, in cc3d.erase
  File "cc3d.pyx", line 937, in cc3d.draw
  File "cc3d.pyx", line 939, in cc3d.__pyx_fused_cpdef
TypeError: No matching signature found

Any idea

Hi there, thanks for writing in!

Based on a cursory look at the code, the most likely reason for it to fail like that is if your source cube is not an unsigned integer type. Would you mind checking that out and let me know if that fixes it? This isn't an obvious constraint so my apologies if that's what happened here.

Hi Will, You are right... Casting to bool sorted the problem... Please close the ticket. Dimitris
