how to run test.py correctly and how to visualize the result?

[yaoxingzhi]

thank you for your contribution! I have some questions about test.py, while I running this python file,the result is so weird as the following.

Loading data... 5_hallway_1_KDTree.pkl 6.2 MB loaded in 0.2s 5_hallway_15_KDTree.pkl 2.4 MB loaded in 0.0s 5_WC_2_KDTree.pkl 1.2 MB loaded in 0.0s 5_conferenceRoom_2_KDTree.pkl 3.7 MB loaded in 0.0s 5_conferenceRoom_1_KDTree.pkl 1.9 MB loaded in 0.0s 5_WC_1_KDTree.pkl 1.3 MB loaded in 0.0s 5_hallway_14_KDTree.pkl 1.4 MB loaded in 0.0s 5_hallway_12_KDTree.pkl 1.4 MB loaded in 0.0s 5_hallway_13_KDTree.pkl 2.4 MB loaded in 0.0s 5_hallway_11_KDTree.pkl 1.5 MB loaded in 0.0s 5_hallway_5_KDTree.pkl 5.1 MB loaded in 0.0s 5_conferenceRoom_3_KDTree.pkl 2.8 MB loaded in 0.0s 5_hallway_3_KDTree.pkl 2.3 MB loaded in 0.0s 5_hallway_10_KDTree.pkl 2.2 MB loaded in 0.0s 5_hallway_4_KDTree.pkl 1.9 MB loaded in 0.0s 5_hallway_2_KDTree.pkl 8.2 MB loaded in 0.0s

And I can not visualize the result about S3DIS task, could you please help me ?

My results are almost the same with you when finishing running test.py. Then if you want to visualize the result, you can try tensorboard --logdir runs, and check the local host printed in the terminal hints. For example, mine is as below. The visualization result is at http://localhost:6006/.

Thank you for your reply, but I'm afraid my problem is not like what you said. What I want to visualize is the point cloud map after the semantic segmentation,I can visulize the result on tensorboard.

maybe you can check the test.py above，the two inputs' dimensions are not correct

Thanks for the suggestion. Have you succeeded in implementing RandLA-Net-pytorch's work?

i occured this question too, whats MiniDijon8.ply meaning?

[MohamedMansour89]

Hi, the problem is in the line where write_ply happens. It tries to write the predictions with tensor size[1,40960] along with cloud with tensor size [40960,3] and there is a mismatching in the second dimension of both. You can just expand your predictions by reshaping it : expanded_predictions = predictions.reshape(-1,1) also do not forget to send the clouds to cpu as well in order to avoid converting the cuda device tensor to numpy : cloud = points.squeeze(0).cpu().numpy()[:, :3]

hope this works for you

Hi, the test.py seems to only display partial results of point clouds, and the coordinates of the point cloud are different from the original point cloud.
