Hi @aespielberg , did you build the library yourself or use the release package? If you built it yourself could you confirm if it was built with CUDA support enabled?

I think I ran into similar issues on Ubuntu 21.04, CUDA 11.4, both when building warp (with export CUDA_PATH=/usr/local/cuda set properly) and using the release package.
It seems Omniverse officially supports Ubuntu 18.04. A workaround to this is to run warp in Docker, I used the Isaac Sim container with some modifications:
FROM nvcr.io/nvidia/isaac-sim:2021.2.1
RUN apt-get update \
&& apt-get install -y -qq --no-install-recommends \
wget \
git \
vim \
sudo \
build-essential \
software-properties-common \
&& apt-get clean && rm -rf /var/lib/apt/lists/*
RUN wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-ubuntu1804.pin \
&& mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600 \
&& apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/7fa2af80.pub \
&& add-apt-repository "deb https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/ /"
RUN apt-get update \
&& apt-get -y install cuda-toolkit-11-4 \
&& apt-get clean && rm -rf /var/lib/apt/lists/*
ENV PATH /usr/local/cuda/bin:$PATH
ENV LD_LIBRARY_PATH /usr/local/cuda/lib64:$LD_LIBRARY_PATH
RUN mkdir /root/.local/share/ov/pkg/ && ln -s /isaac-sim /root/.local/share/ov/pkg/isaac_sim-2021.2.1
RUN ln -sf /isaac-sim/kit/python/bin/python3 /usr/bin/python
ENV PATH /isaac-sim/kit/python/bin:$PATHfrom warp.

Thank you both for the replies. Yes, I foolishly forgot to set the CUDA_PATH. I have now set it to /home/user/anaconda3/envs/warp/, and cuda objects were built. I also set LD_LIBRARY_PATH to $CONDA_PREFIX/lib.
however, now on runtime it is a new error:
$ python examples/example_raycast.py
Traceback (most recent call last):
File "/home/user/scratch_space/warp/warp/examples/example_raycast.py", line 23, in <module>
wp.init()
File "/home/user/scratch_space/warp/warp/warp/context.py", line 1097, in init
runtime = Runtime()
File "/home/user/scratch_space/warp/warp/warp/context.py", line 536, in __init__
raise Exception("Warp Initialization failed, CUDA not found")
Exception: Warp Initialization failed, CUDA not found
Not sure how to debug this error.

This usually means that the CUDA driver is not installed correctly on your system. If you run nvidia-smi from the command line do you see visible CUDA devices?

Wow, crazy, those drivers were there just two days ago.
That was indeed the problem. Thank you!
