how to modify the prune function #198

Closed medif closed 3 years ago

Hi, I have a dataset without rgb values with 9 classes labeled and the format is .npy (type float32) I changed the line like: xyz,labels = libply_c.prune(xyz, args.voxel_width,np.zeros(xyz.shape,dtype='u1'),labels,np.zeros(1, dtype='uint8'),9,0) but it throw an error IndexError: vector::_M_range_check: __n (which is 64) >= this->size() (which is 10)

, any suggestions please Thank you

Did you figure it out?

Otherwise please report the value of .shape and dtype for xyz and labels.

Can you help me please

why is the label type 'f2'? it should be 'uint8'.
