如果你想要避免w y导致的错误，这是一个可以参考的办法。If you want to avoid the errors caused by w and y, here is a possible solution.

注释掉整个pinyinRewrite函数以及对它的调用，这将不会影响结果!
Make the function "pinyinRewrite" useless!

复制下面的代码，替代utils/pinyin.py的内容：
Replace utils/pinyin.py with following codes:

import os
import pickle

from pypinyin import pinyin, lazy_pinyin, Style
from dimsim.utils import maps

class Pinyin:
consonantList = maps.consonantList
vowelList = maps.vowelList

def __init__(self, pinyinstr):
    self.tone = int(pinyinstr[-1])
    self.locp = pinyinstr[0:-1].lower()
    self.consonant, self.vowel = self.parseConsonant(self.locp)
    # self.pinyinRewrite()

def parseConsonant(self, pinyin):
    for consonant in self.consonantList:
        if pinyin.startswith(consonant):
            return (consonant, pinyin[len(consonant):])
    # it's a vowel without consonant
    if pinyin in self.vowelList:
        return None, pinyin.lower()
    
    print("Invalid Pinyin, please check!")
    return None, None
    
def toStringNoTone(self):
    return "{}{}".format(self.consonant, self.vowel)
