• PointTransformer:
  Download the datasets and set the environments following the project point-transformer. The experiments are running on 4 NVIDIA GeForce RTX 3090.

• Training
  Name exp of exp_dir in ./tool/train.sh;
  Configure data_root, test_list, test_list_full, and names_path in ./config/s3dis/s3dis_pointtransformer_repro.yaml;
  Configure cutmix, data_split, open_eval, alpha, and select_ratio in ./config/s3dis/s3dis_pointtransformer_repro.yaml.

sh train.sh

• Testing
  Name exp of exp_dir in ./tool/test.sh;
  MSP and MaxLogits methods share the same training process;
  Even open_eval is set to "msp" in the training stage,
  configure open_eval to "maxlogit" for evaluating MaxLogits.
