No checkpoint directory

[HCCda]

Hi~When I render with your pre-trained model,I have encountered a question that"
No checkpoint directory found at outputs/kitti-recon-65-120/mars-kitti-car-depth-recon/2023-10-30_212654/nerfstudio_models",I have made new directories and put the file "step-000400000.ckpt " into it ,how can I solve this problem?Thank you for you reply.

Hi! @HCCda

It seems like you haven't uploaded the screenshot successfully. But I propose you make a directory using the same path shown above.

Hi,Thank you for you reply. I have made the directory like above.The path of checkpoint file is /home/a/data/outputs/kitti-recon-65-120/mars-kitti-car-depth-recon/2023-10-30_212654/nerfstudio_models/step-000400000.ckpt. It seems that the code could not find the checkpoint file correctly. How can I change the checkpoints path in the program?

relative directory issue? Given your path of ckpt file, it works only if your code is also under /home/a/data/
I guess you might solve this by debugging deeper into this https://github.com/nerfstudio-project/nerfstudio/blob/88873ef3abac208d0fe6e90d06c044900762b01a/nerfstudio/utils/eval_utils.py#L101

1. Maybe you can modify the load_checkpoint in config.yml for your checkpoint path?
2. The default option is to locate the output directory in mars repo, you can move the outputs directory in mars repository, like mars/outputs/kitti-recon-65-120/mars-kitti-car-depth-recon/2023-10-30_212654/nerfstudio_models/step-000400000.ckpt.

I modified the location of "cicai_render.py" and solved the problem.Thank you for you reply.
I meet an another question,I want to render the depth images,I change the "rgb" into "depth" as following: "the rendered_output_names: List[str] = field(default_factory=lambda: ["depth"])". But it has an error that 'str' object has no attribute 'suffix' in "data_utils.py" .What is the reason for this situation？

That really the relative directory issue.I have solved the problem,thank you.

Hi @HCCda

You can try adding the following lines in data_utils.py.

    # resolve the filepath
    if not isinstance(filepath, Path):
        filepath = Path(filepath)
