non-precise type array

[Imran Akbar]

Hi,

I've got a function like this:

from numba import jit, types

from numba.typed import Dict

@jit(nopython=True)

def metrics_from_matrix(confusion_matrix):

    zero_matrix = np.zeros(confusion_matrix.shape)

    metrics = Dict.empty(

          key_type=types.unicode_type,

          value_type=types.float64

    )

I get a 'non-precise type array(pyobject,1d,C)' error on the "zero_matrix" line, and if I comment that out, on the "metrics = Dict" line as well.

Any ideas on how to fix this?

thanks
