UnicodeDecodeError: 'ascii' codec can't decode byte 0xdf in position 0: ordinal not in range(128)

Hi,
When I run the neuralTensorNetwork.py file, I have encountered this problem:
I use Python 3.6.

Traceback (most recent call last):
File "neuralTensorNetwork.py", line 764, in
neuralTensorNetwork()
File "neuralTensorNetwork.py", line 710, in neuralTensorNetwork
word_indices, num_words = getWordIndices('wordIndices.p')
File "neuralTensorNetwork.py", line 591, in getWordIndices
word_dictionary = pickle.load(open(file_name, 'rb'))
UnicodeDecodeError: 'ascii' codec can't decode byte 0xdf in position 0: ordinal not in range(128)

Does anyone know how to solve it?

Thanks.
