np.random.choice raised System.NotSupportedException

[alvinfebriando]

error on np.random.choice, it said "Specified method isn not supported". Is my usage wrong?

var score = np.arange(1,6);
var p = new[] { 0.2, 0.2, 0.2, 0.2, 0.2 };
var result = np.random.choice(score, probabilities: p);

I created a test case with your exact code and ran it using my dev fork of NumSharp. No errors were produced. Are you using an out dated NumSharp?

This has been fixed. np.random.choice now works:

np.random.seed(42);
var result = np.random.choice(5, 3, true);  // Works: [3, 4, 2]
