zip nerf is not working 360.gin file is missing

[sumanttyagi]

as soon we start to train a model after processing an images with comlap.

below isssues are coming

Have you try this way? It works with Linux. I never test on Windows

pip install nerfstudio==1.0.3
pip install git+https://github.com/NVlabs/tiny-cuda-nn/#subdirectory=bindings/torch

git clone https://github.com/SuLvXiangXin/zipnerf-pytorch.git
cd zipnerf-pytorch
pip install ./extensions/cuda
pip install torch-scatter -f https://data.pyg.org/whl/torch-2.0.0+${CUDA}.html

pip install -e . 
ns-install-cli

Then you will able to run this command

ns-train zipnerf nerfstudio-data --data path/to/your/data

[sumanttyagi]

@ichsan2895 Please check wil running pip install ./extensions/cuda

@sumanttyagi I ran into that error during Zipnerf install, and was able to resolve that error by setting the C++ version:

set NVCC_APPEND_FLAGS=-std=c++17

But trying to install torch-scatter broke my installation, possibly because of torch 2.0 (in)compatibility.

I still have the /configs/360.gin error.

[koktavy]

Ah, I was able to provide the 360.gin file manually and start training!

It's looking for /configs/360.gin relative to the command directory. So if you're running your command from the root folder of nerfstudio like I am, create the configs folder in nerfstudio. We'll see how the training goes 🤞

Next step for me will be to run the Reality Capture poses through Zip NeRF instead of the COLMAP pose data, if possible.

@koktavy

• [ ] it should come from the repo the 360.gin file this is pure bug or this steps should be mentioned in repo

• [ ] and also can you explain each parameter of 360.gin file how to set it for custom dataset to train model

• [ ] [THIS WORKED FOR ME ]also the above bug is linked to something else for me Uninstall the ninja library then reinstall the process at last do pip install ninja this is the know issue mentioned on other or parent repo STILL THE 360.GIN FILE WILL BE MISSING BUT env will be created

[sumanttyagi]

• [ ] Also with manually placing the 360.gin file is giving very poor results clouds like noise everywhere in nerf model please check if it coming from original model

[koktavy]

I agree, it should be included, something is not right.

After training "finished" the results did not converge. I'm not familiar with the GIN file and what the parameters control, I was hoping it would be set to ideal defaults.

With the env created are you able to train successfully or you have the same error?

[sumanttyagi]

@koktavy not working please revisit the code
