about absence of DeformableTransformer_backbone.py

[wangsch10]

Hi~
I I noticed that in CoAlign/opencood/models/point_pillar_deform_transformer.py line 11：
from opencood.models.sub_modules.deformable_transformer_backbone import DeformableTransformerBackbone
But there is no deformable_transformer_backbone.py in CoAlign/opencood/models/sub_modules.
May i ask where can i find deformable_transformer_backbone.py.
Thank you, looking forward to your reply！谢谢！

Hi, that code snippet is deprecated, as well as CoAlign/opencood/models/point_pillar_deform_transformer.py.
