qiskit-aer-gpu is not working

#output

i have installed required packages and also i have nstalled cuda

I am also focusing on this issue, have you ever installed qiskit_aer_gpu ?

I’ve encountered this issue as well. Using qiskit-aer-gpu in a fresh Python environment with the required dependencies resolved it for me, and the device='GPU' option no longer throws the RuntimeError. Hope this helps!
