GPUs not supported by lightning.gpu?

Hi, I have following issue with lightning.gpu

I got following:
pennylane_lightning_gpu.lightning_gpu_qubit_ops.PLException: [/pennylane-lightning-gpu/pennylane_lightning_gpu/src/simulator/StateVectorCudaBase.hpp][Line:262][Method:StateVectorCudaBase]: Error in PennyLane Lightning: forward compatibility was attempted on non supported HW

My GPUs are:
GPU 0: NVIDIA GeForce RTX 3060 (UUID: GPU-6e0bc274-c6fe-6a83-bf40-413da2855a4b)
GPU 1: NVIDIA GeForce RTX 3090 (UUID: GPU-2c89cf38-7f0f-c5a5-bad2-4d2f26396c1a)

Are these GPUs really not supported?
THX in advance

Hi @cbrandner, welcome to the forum!

In order to use lightning.gpu you need NVIDIA’s cuQuantum library too. cuQuantum expects a CUDA device with Volta or Ampere architectures (see, so it may not run on consumer devices if that is the target.

One option to access supported machines is through Amazon Braket. You can learn more on the PennyLane blog or the Amazon Braket blog.

Please let us know if this helps.

Thank you very much. I should have read all notes, :slight_smile:,

That’s ok! I’m glad I could help :slightly_smiling_face: .
