Batch size ablation results

2

Hello, thanks for your great work. Can you provide additional ablations obtained using different batch size ? (e.g. smaller batch size 512/256, instead of the 1024 reported in paper) I...

你好，我想问一下您自己写的预处理 和 官方提供的那个预处理数据集有区别吗。

I evaluate the example pre-trained models on 100 trajectories. I set the seed to 0. I run the following command twice: ``` python -m tools.run_rl configs/bc/mani_skill_point_cloud_transformer.py --gpu-ids=0 --evaluation \ --work-dir=./test/OpenCabinetDrawer_1045_link_0-v0_pcd...

Incorrect Image Normalization

Hi @cheng-chi, this work is incredible! I read the code carefully and I have a doubt about image normalization. For example, in `real_pusht_image_dataset.py`, the following code normalizes the image to...
