Error in .ply

TriangleMesh with 51069949 points and 0 triangles. sample pcd from mesh: 11%|█████ | 1/9 [00:07<01:02, 7.76s/it]Traceback (most recent call last): File "pc_eval.py", line 70, in new_pts = np.concatenate(new_pts, axis=0) File "<array_function internals>", line 180, in concatenate ValueError: need at least one array to concatenate

Hi, I use IterMVS (CVPR 2022) to generate .ply, however during the evaluation, I encountered an error that there is no triangles, how can I solve it？

Hi @gangweiX, I guess you are evaluating point clouds. If so, you need to specify that in the arguments by --mode pcd.

Ok, thanks.
