Tensor True Div operator output not equal with Numpy (though they are) #51

Open gunjannandy opened 5 years ago

gunjannandy commented 5 years ago

test / swig / tensorAssignmentOperators.py (Line No. 619, 627, 651)

Here is the snippet of code

# float_tensor /= bool_scalar
  def test_Assignment_True_Div_float_tensor_bool_scalar (self):
    temp_np = self.np_float_0_4.copy()
    temp_np /= True
    temp_dc = self.dc_float_0_4.copy()
    temp_dc /= True
    np.testing.assert_array_equal(temp_np, np.array(temp_dc.data()))

  # float_tensor /= int_scalar (Numpy and Dnnc has same output, but says not equal)
  def test_Assignment_True_Div_float_tensor_int_scalar (self):
    temp_np = self.np_float_0_4.copy()
    temp_np /= 5
    temp_dc = self.dc_float_0_4.copy()
    temp_dc /= 5
    np.testing.assert_array_equal(temp_np, np.array(temp_dc.data()))

  # float_tensor /= float_scalar (Numpy and Dnnc has same output, but says not equal)
  def test_Assignment_True_Div_float_tensor_float_scalar (self):
    temp_np = self.np_float_0_4.copy()
    temp_np /= 5.0
    temp_dc = self.dc_float_0_4.copy()
    temp_dc /= 5.0
    np.testing.assert_array_equal(temp_np, np.array(temp_dc.data()))

  # float_tensor /= float_tensor (Numpy and Dnnc has same output, but says not equal)
  def test_Assignment_True_Div_float_tensor_float_tensor (self):
    temp_np = self.np_float_0_4.copy()
    temp_np /= self.np_float_5_9
    temp_dc = self.dc_float_0_4.copy()
    temp_dc /= self.dc_float_5_9
    np.testing.assert_array_equal(temp_np, np.array(temp_dc.data()))

The tensor\/=tensor\ works, but tensor\/=tensor<int/float/double> doesn't. As output it shows:
