OPTIX_ERROR_LIBRARY_NOT_FOUND when running NS Train #5

Closed neekolas closed 1 year ago

neekolas commented 1 year ago

I am so close to getting this working, but am getting an error when running ns-train.

Steps To Reproduce

This is all being run on a Lambda Cloud VM with an A10 GPU

  1. Upload the Linux install script for Optix 7.5 to the VM (I can only find 7.5 and 7.7, but not 7.6 on Nvidia's site), run it, and move the outputs to $HOME/optix
  2. Put my source images in the nerf-data folder
  3. Start a NerfStudio Docker container with 
    sudo docker run --rm -it --gpus all -v $HOME/nerf-data:/workspace -v $HOME/optix:/opt/optix dromni/nerfstudio:0.2.2

    (all future commands are run inside the container)

  4. 
export OPTIX_PATH=/opt/optix
git clone https://github.com/jkulhanek/tetra-nerf.git
python3.10 -m pip install -e tetra-nerf
cd ./tetra-nerf
# Pretty sure these next two lines aren't necessary if you are installing from source, but can't hurt
cmake .
make
export FOLDER=/workspace/inputs/bedroom-gimbal-3
# Works great, albeit slow
python3.10 -m tetranerf.scripts.process_images --path $FOLDER
# Works great
python3.10 -m tetranerf.scripts.triangulate --pointcloud $FOLDER/sparse.ply --output $FOLDER/sparse.th

export NERFSTUDIO_METHOD_CONFIGS="tetra-nerf=tetranerf.nerfstudio.registration:tetranerf"

This is where things fail

ns-train tetra-nerf --pipeline.model.tetrahedra-path $FOLDER/sparse.th minimal-parser --data $FOLDER

jkulhanek commented 1 year ago

This could be an old nvidia driver. What is the driver version on the host system? Is it supported by Optix7.5?

jkulhanek commented 1 year ago

I also believe you need to add this “ -e NVIDIA_DRIVER_CAPABILITIES=graphics,compute,utility” to your run command. Can you try it if it helps?

neekolas commented 1 year ago

Driver Version: 525.85.12, which looks fine for Optix 7.5.

I just tried setting the NVIDIA_DRIVER_CAPABILITIES environment variable and it didn't have any effect.

Any other ideas?

jkulhanek commented 1 year ago

Can you if you get the same error with the dockerfile in this repo?

neekolas commented 1 year ago

Same result after cloning this repo and building the image with Optix 7.5 via

sudo docker build -t tetra-nerf:latest --build-context optix=$HOME/optix .

Ok, can you post the output of running with strace as suggested here? https://forums.developer.nvidia.com/t/optix-error-failed-to-load-optix-library/70671/21 Also, what gpu do you use?

jkulhanek commented 1 year ago

What cuda_compute does your GPU support?

neekolas commented 1 year ago

My GPU supports cuda_compute 8.6 (NVIDIA A10).

I ran ns-train tetra-nerf ... with strace. These were the most interesting log lines I could find.

Yes! It is missing the optix library libnvoptix (part of the nvidia driver, not the SDK). Same as here: https://github.com/NVIDIA/nvidia-container-toolkit/issues/187 What docker setup do you use? What version of docker and what version of nvidia container toolkit?

I'm using Docker 23.0.1

Can you check if the library exists on your host system? It should have been a part of the nvidia driver installation.

neekolas commented 1 year ago

Hmmm. find / -name libnvoptix.so.1 doesn't come up with any results. I'll try and reinstall/update the nvidia driver and see if that helps. The drivers are just whatever comes standard in Lambda Cloud instances.

neekolas commented 1 year ago

After re-installing the Nvidia drivers on the host via apt-get, it seems to be working!

Thanks so much for all the help. I'll let you know how the results look in 13 hours or so.

jkulhanek commented 1 year ago

I am glad you were able to find the source of the error. Thank you for investing your time into debugging.

liuxiaozhu01 commented 1 year ago

I met the question either. Does the libnvoptix.so.1 occur as long as re-installing the nvidia driver? I have no permission to modify the driver😭 I am wondering whether there is any other solutions?

jkulhanek commented 1 year ago

I am sorry, but I believe the only solution is fixing the driver. If you try manually copying the libnvoptix lib (matching version) and adding it to the library path, that could also work, but unlikely.

thank you for your reply. I will go on try it.

Same issue with the docker, here's how I fixed it for anyone looking here:

installed optix manually from https://developer.nvidia.com/designworks/optix/download - downloads NVIDIA-OptiX-SDK-7.7.0-linux64-x86_64.sh & then extracts into the folder "NVIDIA-OptiX-SDK-7.7.0-linux64-x86_64" un-installing then re-installing nvidia drivers.

Pointing to the location of my data & pointing the optix install path.

docker run -v C:/Users/Thomas/Desktop/PythonProjects/Nerf/Nerfstudio/Colmap_Data/TempDocker:/workspace/mydata --rm -it --gpus all -p 7007:7007 kulhanek/tetra-nerf:latest 
export OPTIX_PATH=$workspace/mydata/NVIDIA-OptiX-SDK-7.7.0-linux64-x86_64
export NVIDIA_DRIVER_CAPABILITIES=graphics,compute,utility
