A issue about 12HZ data generation

[Miayui]

When I tried to run bash scripts/ann_generator.sh 12 --ann_strategy 'interp', the terminal show

...
total samples in val: 6019 
...

After that, i tried to run python tools/create_data.py nuscenes --root-path ../data/nuscenes --out-dir ../data/nuscenes_mmdet3d-12Hz --extra-tag nuscenes_interp_12Hz --max-sweeps -1 --version interp_12Hz_trainval, the terminal show

...
total scene num: 850
exist scene num: 150
train scene: 0, val scene: 150
...

I think it means the 12HZ data generation only generate val dataset.
Though I already know you have released all the pre-generated annotations, i still hope you could share the method for generation 12HZ train dataset, since i might use my own dataset later.
Thank you so much for your great work! Looking forward to your reply!

You can find the related code here. I remember that ASAP indeed only contains the val. set by default, and manual changes have to be made in their code.

I will try to search for my old materials in the following days. In the meantime, I hope the information above helps you.

Thank you for your help, it's useful to me! According to your prompt:

• I deleted all the error files that were generated earlier(it seems important, otherwise, the following changes cannot take effect)
• I tried to change the related code to :

-----origin-------
val_scene_ids = splits['val']
-------------------
----change_to----
scene_ids = splits['train']
val_scene_ids = splits['val']
scene_ids.extend(val_scene_ids)
------------------
------------------
other 'val_scene_ids' change to 'scene_ids'

• run bash scripts/ann_generator.sh 12 --ann_strategy 'interp'
• run python tools/create_data.py nuscenes --root-path ../data/nuscenes --out-dir ../data/nuscenes_mmdet3d-12Hz --extra-tag nuscenes_interp_12Hz --max-sweeps -1 --version interp_12Hz_trainval and the terminal show:

...
total scene num: 850
exist scene num: 850
train scene: 700, val scene: 150
...

It works! Thank you for your help again!

Glad to hear that!
