Hin2vec2.7转3.5运行调试TypeError: a bytes-like object is required, not 'str'问题

在调试Hin2vec的时候，出现了TypeError: a bytes-like object is required, not ‘str’，源代码为2.7，我改成3.5运行之后就报错了。
在python3中需要加入encoding=’bytes’，而python2中不需要。
1.报错如下
TypeError: a bytes-like object is required, not ‘str’
2.源代码

def load_a_HIN_from_pickle_file(fname):
    '''
        Load a HIN from a pickled file
        The pickled file can be generated by tools/pickle_a_HIN.py
    '''
    g = pickle.load(open(fname))
    # 输出class_,count,edg_class2id
    g.print_statistics()
    return g

3.修改之后的代码

def load_a_HIN_from_pickle_file(fname):
    '''
        Load a HIN from a pickled file
        The pickled file can be generated by tools/pickle_a_HIN.py
    '''
    g = pickle.load(open(fname, 'rb'), encoding='bytes')
    # 输出class_,count,edg_class2id
    g.print_statistics()
    return g

4.成功解决
