Stat weights are no longer a thing - we've proved the balance between your stats is more important.
But if you really want you can still get stat weights from the simulator. Run a Gear Simulation, and on the results page scroll paste the Machine Learning - Stat weight sections is after it.
They will only roughly apply, and even then they only apply to your specific build/gear as it is right now. A single item change and you'll need new stat weights.
