该数据集名为pusht_336，是一个336像素的PushT PPO成功轨迹数据集。轨迹由与pusht_v0相同的1Hz PPO PushT求解器生成，包含渲染图像，存储在history[*].image、image_prev和image_next字段中，图像分辨率为336x336，JPEG质量为85。数据集用于强化学习和机器人视觉任务，包括训练和测试分割，训练集有500,000条记录，测试集有200条记录，格式为gzip压缩的JSONL。动作坐标使用PushT 512x512世界/图像坐标系。数据集旨在支持机器人操作和视觉语言模型的研究。

The dataset is named pusht_336 and is a 336px PushT PPO successful trajectory dataset. The trajectories are generated by the same 1Hz PPO PushT solver used for pusht_v0, with rendered images in history[*].image, image_prev, and image_next at 336x336 resolution and JPEG quality 85. It is used for reinforcement learning and robotics vision tasks, with train and test splits containing 500,000 and 200 records respectively, in gzip-compressed JSONL format. Actions use the PushT 512x512 world/image coordinate system. The dataset supports research in robotic manipulation and vision-language models.
