How did you define K, the limited number of voxels in the paper?

K is the max voxel number in the paper and the author said "it is possible to only store a limited number of voxels (K) and ignore points coming from voxels with few points". But I cannot find where you define K in the code. For example, # [ΣK, 35/45, 7] self.feature = tf.placeholder(tf.float32, [None, cfg.VOXEL_POINT_COUNT, 7], name='feature') where K can be any shape in class FeatureNet. Could you please explain why? Thanks!

It is available in preprocess.py under utils. Check here.
