Preprocessing on Scannet

[xjdexjt]

When I run the processing code for scannet, the following results is obtained.


Then, the code is finished, and the data is not processed.

Besides, I check the code, but I cannot find any processing functions are used in "init".

Could you give me any advice on how to processing the data.

Thanks.

OK, I solved.
Thanks for your great work.

while running s3dis_preprocessing.py i got just this screen, can you please let me know how to proceed further.

Thanks in advance

Hi!
You miss the command preprocess when calling s3dis_preprocessing.py.

                                                 |
                                                 v
datasets/preprocessing/s3dis_preprocessing.py preprocess \
--data_dir="PATH_TO_Stanford3dDataset_v1.2" \
--save_dir="../../data/processed/s3dis"

Let me know if this solves your problem :)

Best,
Jonas

got it thank you so much will try them, one more doubt is there is any inference script which will take single .ply and gives out instances , it will be very helpful

getting this error when i run script of preprocessing of s3dis
FILE SIZE DOES NOT MATCH FOR /home/sai/mythili_wd/Segmentation/Mask3D/Stanford3dDataset_v1.2_Aligned_Version/Area_5/lobby_1/lobby_1.txt
(1162766 vs. 1223236)

totally agree! #11 deals with this, already. Will take some time for this :)

this is only a debug message. You can ignore it.

ValueError: the number of columns changed from 6 to 5 at row 180389; use usecols to select a subset and avoid this error

Thanks for the reply ,but at the end its showing error for Area_5 of s3dis

[JonasSchult]

Interesting! I will take a look into this tomorrow. Thanks for letting me know!

[Mythili-kannan]

Thank you waiting for the reply!!

[JonasSchult]

I figured out what went wrong. Thank you very much for bringing it to my attention! :)

There is a coding error in Area_5/hallway_6/Annotations/ceiling_1.txt in line 180389.

I just deleted the bad character. That solved the issue.

Moreover, you need to rename Area_6/copyRoom_1/copy_Room_1.txt to Area_6/copyRoom_1/copyRoom_1.txt as it breaks the naming convention.

I fixed these issues early in the project and forgot about describing them in the README. I will adapt the s3dis preprocessing script that it won't cause trouble in the future.

Thanks again! :)

Thanks for the reply, that error got fixed, awaiting for inference code :)
