WebbRuntimeError: philox_cuda_state for an unexpected CUDA generator used during capture. In regions captured by CUDA graphs, you may only use the default CUDA RNG generator on the device that's current when capture begins. If you need a non-default (user-supplied) generator, or a generator on another device, please file an issue. WebbChange the generator seed and algorithm, and create a new random row vector. rng (1, 'philox' ) xnew = rand (1,5) xnew = 1×5 0.5361 0.2319 0.7753 0.2390 0.0036. Now restore the original generator settings and create a random vector. The result matches the original row vector x created with the default generator. rng (s) xold = rand (1,5)

The Philox constructor then carries out offset/4 (a uint64_t division) to compute its internal offset in its virtual Philox bitstream of 128-bit chunks. In other words, it assumes the incoming offset is a multiple of 4.
