Support of VG-150 Dataset

[ShunchiZhang]

Hi, I noticed that this codebase doesn't support VG-150 Dataset.

OpenPSG/README.md

Lines 248 to 251 in ae418a1

	### Supported datasets (Welcome to Contribute!)
	- [ ] VG-150 (IJCV'17)
	- [x] PSG (ECCV'22)

Do you have any plans to support it in the future? I'm glad to contribute if you'd like to sync the progress of this feature with me.

Yes, @king159 and @wzy27 are trying to support VG-150.
I will discuss with them when they finish their final exams.

That would be nice. Thanks!

Still want to ask the same question, it would be wonderful to seethe progress in VG-150.

Please download the VG dataset here, and put it into ./data dir.
We have https://github.com/Jingkang50/OpenPSG/blob/main/openpsg/datasets/sg.py to process the dataset.

Thanks to your work!
Does it mean that we can now train detr-like models proposed in the paper on the VG-150 dataset?
I have put VG-100K in ./data and here is my dir, is this right?
├── data
│ ├──vg150.json
│ ├── VG_100K
│ │ ├── XX.jpg
Then what should I do to train a detr-like model on VG-150? I didn't found the settings of dataset kinds and dirs in config files.
Sorry to bother you and I'm not familiar with this framework.
