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.

What do you mean by not working? Does it say the Q is not positive semi-definite?

If that is the case you may want to read
