I ve had a problem running optix in Windows 11 which occurs either inside or outside of Pycharm IDE. It ssems to be related to multiprocessing.
Nothing is said in the Readme file about the running environment, I ve assumed it runs correctly in any Environment (Windows or Linux). I may have an installation problem.

import optix as opt

Define the objective function

def objective_function(x):
return (x[0]-5) ** 2+4*(x[1]-2) ** 2

if name == 'main':

# Initial guess
xo =[-2.0, -2.0]

optimum = opt.minimize(objective_function, xo, file_tag='_test', n_search = 8, max_processors = 1, line_search = "quadratic", termination_tol = 1e-6, verbose = True)

Running trace as follows:

Thanks for making this software available to test!
