Could share the data preparation code?

[whuhxb]

Hi, I have downloaded the ply data files, but I have some questions: Where is the labels for training data and testing data? How to prepare the data as shown in your paper? Could you please share these files? Thanks.

Hi, @QingyongHu , I have the same questions as @whuhxb 's . The ply download link only provide train and test ply file. No annotation files are found in train folder. Could you upload the annotation file?

THX~

@amiltonwong @whuhxb sorry for my late response!

The semantic label of training data is incorporated in the data file, please refer to herefor details.

The data directory is bit tricky and should be made more clear in Readme.md.

According to the code, the dataset (after preprocessing) shall be

--SensatUrban
   |- grid_0.200
   |- original_block_ply

@serser Thanks for your suggestion.

I will revise the instruction asap.

Best,

Hello ; I have prepared the dataset but I get this error message during training . Can you help me solve this problem

[QingyongHu]

Hi @Lionel2021-belgique,

This is most likely caused by a path error, please check the dataset_path is correct or not.

Best, Qingyong

Hi Sir ; Please I ran the training, but why the values = 0 (the first sentence I underlined in yellow), so I did not understand the error I got at the level of epoch 1 (the second sentence I underlined in yellow) Thank you very much in advance
