这是一个256px重新渲染的PushT PPO轨迹数据集，名为`pusht_v0_256`。数据集的动作轨迹、种子、初始状态以及训练/测试分割均继承自已验证的96px数据集。图像在`history[*].image`、`image_prev`和`image_next`中被重新渲染为256x256分辨率，JPEG质量为85。数据集分为训练集和测试集，训练集包含200,000条记录，测试集包含200条记录，格式均为gzip压缩的JSONL。每条JSONL行代表一个成功的PushT片段，最多包含30个环境动作。重要字段包括`episode_seed`、`history`、`stats`、`init_state`、`init_state_hash`、`env_kwargs`和`solve_kwargs`。动作中的坐标使用PushT 512x512世界/图像坐标系，渲染图像为256px。

This is a 256px rerender of the `pusht_v0` PushT PPO trajectory dataset. The action trajectories, seeds, init states, and train/test split are inherited from the verified 96px dataset. Images in `history[*].image`, `image_prev`, and `image_next` were replay-rendered from the environment at `256x256` and JPEG quality `85`. The dataset is split into train and test sets, with 200,000 records in the train set and 200 records in the test set, both in gzip-compressed JSONL format. Each JSONL row represents one successful PushT episode capped at 30 environment actions. Important fields include `episode_seed`, `history`, `stats`, `init_state`, `init_state_hash`, `env_kwargs`, and `solve_kwargs`. Coordinates in actions use the PushT 512x512 world/image coordinate system. Rendered images are `256px`.
