How to reproduce two-stage training？

[KingofLondon]

Great work. As you mention in your paper sec 4.3, you use both one-stage training and two stage training，and two stage training outperforms one-stage training. But I dont see two stage training in the released code. Can you tell me how to run two stage training with this code?

Hi, thanks for your interest in the project. For the two-stage training approach, you can train the first stage using the standard method. Subsequently, train the second stage by configuring cfg['training']['load_pose_dir'] to the checkpoint directory of the model trained in the first stage, set cfg['training']['load_ckpt_model_only'] to True and set other parameters according to NeRF training. Ensure that cfg['training']['load_dir'] is set to None so that the NeRF model in the initial stage is not loaded.
