Warp CUDA error: Loading module failed

[DrChiZhang]

Hi, I have encountered the following error:

Warp CUDA error 900: operation not permitted when stream is capturing (in function wp_cuda_load_module, /builds/omniverse/warp/warp/native/warp.cu:4080)
Warp CUDA error: Loading module failed
Module newton._src.geometry.kernels 5c3ebb6 load on device 'cuda:0' took 0.23 ms (error)

Any clue to fix this issue?

Your driver is too old to support module loading during a graph capture. Can you upgrade to a driver that satisfies the system requirements https://newton-physics.github.io/newton/guide/installation.html
