AttributeError: 'NoneType' object has no attribute 'shape'

Sorry for long message: I want to send my own data into the Lenet: def genOct(): pod = np.loadtxt('/mnt/zxj/datasets/20221030chuchai/Bianxie_stl2xyz_train/0015/Upper/0.txt') xyz, normal = pod[:, 0:3][0:4096], pod[:, 3:][0:4096] centroid = np.mean(xyz, axis=0)
xyz = xyz - centroid m = np.max(np.sqrt(np.sum(xyz ** 2, axis=1)))
xyz = xyz / m

xyz = xyz.clip(min=-1, max=1)

po = Points(torch.from_numpy(xyz), torch.from_numpy(normal)) # .permute(0,2,1)

octree = Octree(5, 2) octree.build_octree(po)

octree.construct_all_neigh() return octree

def main(): o1 =genOct() -->(for test) change the cloud point into <class 'ocnn.octree.octree.Octree'> o2 = genOct() o3 = genOct() octree = ocnn.octree.merge_octrees([o1,o2,o3]) data = self.get_input_feature(octree).cuda() logits = self.model(data, octree, octree.depth)

I 'm sure the cloud point is not None. Is my operation procedure wrong? If so, what are the correct steps

I suggest first reading the provided examples in debug mode and debugging your own code with some IDEs like vscode.

Thanks for your master piece. I have solved the question. Thanks again
