Missing Checkpoint file

[GrobianTM]

Thank you for providing the project source.

Unfortunately I have encountered an issue when trying to train the network, where a checkpoint file ¨ckpts/r101_dcn_fcos3d_pretrain.pth¨ is missing.

Is this a file you meant to provide?

Command:
$ ./tools/dist_train.sh ./projects/configs/Actformer/Actformer_base.py 1

Error:
