How to use pickneglogsoftmax function?

[thegoldenmeans0]

Hello, everyone!

I'm trying to make program with iris data-set.

I used pickneglogsoftmax() as loss function.

But I got segmentation fault.

Whole program is here.

I used that function as below.

dynet::Expresion y_pred = ...

unsinged int* y_label = 0

dynet::Expression loss_expr = dynet::pickneglogsoftmax(y_pred, y_label)

I'm glad if you tell me how to use pickneglogsoftmax().

Thanks.

Change "unsigned int* y_label" to "unsigned int y_label" and you should be OK.
