The from_tar interface of paddle/v2/parameters.py sets the smaller value to 0.

I did the following tests:

test one

$ od -f ___prelu_layer_0__.w0

0000000   0.000000e+00   5.605194e-45   2.242078e-44   0.000000e+00
0000020  -4.362915e-39   3.391905e-03  -4.271918e-02   5.452635e-02
0000040  -3.064562e-01  -8.415823e-01  -2.167667e-34   2.003883e-03
0000060   1.112373e-34   1.064608e-40   5.219662e-01   2.975052e-02
0000100   6.197284e-38  -6.660666e-40   7.927477e-34  -1.305121e-01
0000120

test two

I print the value in parameter.py,

 def deserialize(self, name, f):
        """

        :param name:
        :param f:
        :type f: file
        :return:
        """
        f.read(16)  # header
        arr = np.frombuffer(f.read(), dtype=np.float32)
        if name == '___prelu_layer_0__.w0':
            print arr

        self.set(name, arr.reshape(self.get_shape(name)))

the print is :

[ -0.00000000e+00   3.39190545e-03  -4.27191779e-02   5.45263477e-02
  -3.06456238e-01  -8.41582298e-01  -2.16766737e-34   2.00388324e-03
   1.11237306e-34   0.00000000e+00   5.21966159e-01   2.97505204e-02
   6.19728394e-38  -0.00000000e+00   7.92747696e-34  -1.30512059e-01]

though the value is very small, but it's useful for my model.
