Bug Description

When trying to run python -m warp.examples.optim.example_drone I get the following error below.

 File "C:\Users\user.name\Source\warp\warp\context.py", line 3265, in get_current_cuda_device
    raise RuntimeError('"cuda" device requested but this build of Warp does not support CUDA')

Thanks for reporting this! I installed this same version of Warp and it successfully runs this example and others on my RTX 3070 with CUDA 12.4 driver.

Did you install the GitHub release package or are you trying to build Warp from source?

[und-miller]

Okay, so I did a complete fresh install of CUDA which resolved the CUDA error from above. However, I am getting a new error from the ShapeInstancer constructor when running python -m warp.examples.optim.example_drone. See below:

    self._axis_instancer = ShapeInstancer(self._shape_shader, self._device)
TypeError: __new__() takes 1 positional argument but 3 were given`

Do you want me to post this error in a new issue?

Thanks for reporting @und-miller, I can reproduce the ShapeInstancer issue on my machine as well. I'll create an issue based on your comment for us to track.

Closing this issue I believe the original issue is now solved.
