Error when running zipnerf method in nerfstudio about nerfstudio HOT 11 OPEN

unfortunately that doesn't work for me either.. it's failing when i pip install ./extensions/cuda

@sblat021 'CUDA_HOME environment variable is not set'. It seems that the CUDA environment variables are not set correctly. Does the following command return true when you execute it?
import torch
torch.cuda.is_available()

from nerfstudio.

I actually know how to fix this! I had this exact issue. I ended up cloning the original pytorch-Zipnerf's repository and that 360config file was in there. I just dropped it into the main nerfstudio folder and it started working.

I also was running into an error where it was looking for the sparse set within COLMAP and I fixed that error by simply just copying the sparse folder from within the COLMAP folder from the dataset I was trying to train and that fixed that issue too

from nerfstudio.

When you say main nerfstudio folder, do you mean: \anaconda3\envs\nerfstudio\Lib\site-packages\nerfstudio ?
I installed nerfstudio using pip.

from nerfstudio.

No, it was just the nerfstudio folder where your training data is hosted. So for me it's just user/name/nerfstudio

from nerfstudio.

Seems bug..
I follow this way from zipnerf-pytorch's website, and it works out of box.

pip install nerfstudio==1.0.1

cd zipnerf-pytorch
git clone https://github.com/SuLvXiangXin/zipnerf-pytorch.git
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

Note: I use Nerfstudio v1.0.1 which have not yet merged between zipnerf-pytorch and nerfstudio

from nerfstudio.

Anyone gotten this to work recently? I've been having similar issues setting this up on both Windows and Linux. Even zipnerf-pytorch project is failing for me on the same step as mentioned above. Any ideas or insights would be appreciated.

from nerfstudio.

Now with Nerfstudio v1.0.2 I have a different issue than mentioned -
Run : ns-train zipnerf
It asks if I want to install the package, Yes.

Errors out on several Windows machines with :

ERROR: Could not install packages due to an OSError: [WinError 5] Access is denied: 'C:\Users\renbr\anaconda3\envs\nerfstudio\Lib\site-packages\cv2\cv2.pyd'
Consider using the --user option or check the permissions.

Error installing method.

Anyone know what to try next ? it's a fresh install (1hr old!) and happens across all my windows machines.

from nerfstudio.

there is another method just make colmap output( sparse data) using nerfstudio's processed data (transform.json) check out here NVlabs/instant-ngp#1080

from nerfstudio.

is this issue resolved please share the solution

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

from nerfstudio.
