#           This file was automatically generated from src/transformers/models/cosmos3_omni/modular_cosmos3_omni.py.
#               Do NOT edit this file manually as any edits will be overwritten by the generation of
#             the file from the modular. If any change should be done, please apply the change to the
#                          modular_cosmos3_omni.py file directly. One of our CI enforces this.
