It seems in your algorithm there is an infinite loop. Following are the places where you can find it:

1. Check len(paramaters) if len(paramaters) >>1 then it will take long time to complete.
2. Check your hamiltonian, loss function, or any other observable if it is diverging (hence cannot be converged).
   Tip:
   For optimization problems use tqdm and GPUs or HPCs as they take alot time.

I run my 4-vertex example by copying the whole notebook code on Google colab, adding
print(len(parameters))
after the original code, and run it in the same time, it currently ran for 4 hours, and the length did not have an output.

After 12 hours, my notebook on Google Colab stopped running after the kernel stopped automatically, the picture is here:

The length of parameters is still not given.

Hey! @OuCheng-Fu i can understand how it feels to wait hrs to get results. For debugging purposes please share your code or colab notebook so that i can better understand problem . I really suggest to not use git /github platform for code discussions use slack or stack overflow for that.

The python code on colab notebook is here:

it is also on slack:
