Hi!
I tried to use my own test ply data(All renamed as the shown format) uploaded to the directory dataset/scannetv2/test to run the test with pretrained model. And I met some bugs when I run test.py. More information is listed below:

CUDA_VISIBLE_DEVICES=0 python test.py --config config/hais_run1_scannet.yaml --pretrain ~/HAIS/HAIS/pretrain/hais_ckpt.pth
/home/harris_huang/HAIS/HAIS/util/config.py:22: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
config = yaml.load(f)

It seems like no test data is loaded, how can I solve this issue? thanks!
