Note that:

- If the preprocess of Waymo dataset is very slow or blocked, you could modify the `--workers` to a smaller number. If it still can't be solved, you could set the `--workers` as 0 to avoid using multiprocess.
- In case the preprocessing of Waymo dataset is slow or blocked, consider reducing the value of `--workers`. If this doesn't resolve the issue, you could set `--workers` as 0 to avoid using multiprocess.
- If your local disk does not have enough space for saving converted data, you can change the `--out-dir` to anywhere else. Just remember to create folders and prepare data there in advance and link them back to `data/waymo/kitti_format` after the data conversion.
**Tips**:
- **Ready-made Annotations**. We have provided the annotation files generated offline [here](#summary-of-annotation-files). However, the original Waymo data still needs to be converted to kitti-format data by yourself.

- **Waymo-mini**. If you just want to use a part of Waymo Dataset to verify some methods or debug quickly, you could use [Waymo-mini](https://download.openmmlab.com/mmdetection3d/data/waymo/waymo_mini_kitti_format.tar.gz) we provided. It only contains two segments in train split and one segment in val split from the original dataset. We have processed all the images, point clouds and annotations offline. What you should do is only downloading, and then unzipping the file to `data/waymo/`:

```bash

- **Faster evaluation**. If you want faster evaluation on Waymo, you can download the preprocessed [metainfo](https://download.openmmlab.com/mmdetection3d/data/waymo/idx2metainfo.pkl) containing `contextname` and `timestamp` to the directory `data/waymo/waymo_format/`. Then, the dataset config is modified like the following:
