I‘m new to this ,

Thanks for help.

This has been fixed. np.random.choice with probabilities now works correctly:

np.random.seed(42);
var probs = new double[] { 0.1, 0.2, 0.3, 0.4 };
var result = np.random.choice(4, 5, true, probs);
// Result: [2, 3, 3, 2, 1]

The underlying cumsum issue that caused the NotSupportedException has been resolved.

Resolved via #600, #602, #603, #596.
