I have the same problem described here CVXPY Quadratic Programming; ArpackNoConvergence error.
I would like to try the pertubation/trasformation solution, but i have no idea how to perform it.
I have a quadratic problem like this https://www.cvxpy.org/examples/basic/quadratic_program.html, and all the matrix P, q, G, h, A, b.
The solver works as long as the matrix are small (like 150 items). But with larger problems i get the problem above.
Would really appreciate if someone could explain me how to perturb datas (with Python).
Thank you.
