ZeroFlow validation error.

[frankkim1108]

Hi @Kin-Zhang
Thank you for making your amazing work public.

I am currently trying to run validation with ZeroFlow on the Waymo dataset.
I followed the instructions and downloaded the data and preprocessed it.

Also, as metioned in the instruction, I converted the ZeroFlow checkpoint to OpenSceneFlow style with zerof2ours.py.
However, there were issues with state dict key errors and a mismatch in model layer shapes.

The checkpoint I downloaded for validation on Waymo with Zeroflow is
nsfp_distilatation_scaled.ckpt.

It would be grateful for your guidance.
Thank you again for your time and your great work.

I see, could you provide the zeroflow waymo ckpt link directly? I forget where can I found them now...

I think once I get the link, I can fix it quickly.
