ERROR tinycudann_bindings

[OliverV12]

I was replicating your project and initially installed it with CUDA 12.3. Following your instructions, I set up the environment with Python 3.10 since the 'tiny-cuda' package wasn't available. The environment creation steps are as follows:

conda create --name auto_recon -y python=3.10
conda activate auto_recon
python -m pip install --upgrade pip setuptools

Following your recommendations, I proceeded with the installation of AutoDecomp and I installed PyTorch using the following commands:

conda install pytorch==1.13.1 torchvision==0.14.1 torchaudio==0.13.1 pytorch-cuda=11.7 -c pytorch -c nvidia

With these commands, I created an environment containing a different version of CUDA (11.7) compared to the system's CUDA (12.3).
The installed version of PyTorch3D obtained from Anaconda Cloud using the command:

conda install pytorch3d -c pytorch3d

is:

pytorch3d 0.7.5 py310_cu117_pyt1131 pytorch3d

For the 'tiny-cuda' installation, I initially attempted the following command:

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

However, the system reported an incompatibility between the CUDA version of 'tiny-cuda' and the system's CUDA version (12.3).

Upon further investigation on this issue at this link:

NVlabs/tiny-cuda-nn#372

I discovered that it's possible to install 'tiny-cuda' with Python 3.10 and CUDA 11.7 (my Anaconda environment). I used the following command for installation:

pip install https://huggingface.co/camenduru/CoDeF/resolve/main/tinycudann-1.7-cp310-cp310-linux_x86_64.whl

This successfully installed 'tiny-cuda', after which I followed all other instructions to complete the project.
However, upon running the command:

bash exps/code-release/run_pipeline_demo_low-res.sh

I encountered an error related to 'tinycuda_bindings':

Could you provide insights into resolving this error?

[Zeng-Fan-Yi]

It seems that the error may appears here in AttributeError: 'pycolmap. Image' object has no attribute 'rotmat'，This error is caused by a recent update to pycolmap, and I am also struggling with this error while running this project. If you find a solution, I hope you can communicate with me.
