I'm making good progress in converting an existing Python script across to VB.NET (please don't ask why), but have run into an issue accessing a numpy array using the row / column index. I feel pretty stupid not being able to sort this, having converted the bulk of the code successfully, so would appreciate any direction. Code snippet:

Dim nparray_A = np.random.rand(7, 5)
Console.WriteLine(nparray_A(3)) ' outputs the 4th row from the array
Console.WriteLine(nparray_A(3,3)) ' fails

Tried passing in a tuple of (3,3), but same issue. Any ideas? Thanks

If it is a 4x4 array then `nparray_A(3, 3)` would be correct, but perhaps it is an array of arrays and needs `nparray_A(3)(3)`. – Andrew Morton Jun 18 '20 at 13:53
Of course! That did the trick. Many thanks for the advice. – ChromeBeat Jun 19 '20 at 06:37
