gensim.models.wrappers.LdaMallet（）报错，如何解决

输入代码如下：

import gensim
import gensim.corpora as corpora
from gensim.utils import simple_preprocess
from gensim.models import CoherenceModel

import os
os.environ.update({'MALLET_HOME':r'C:/Users/Pying/Downloads/mallet/mallet-2.0.8/'})

mallet_path = 'C:\\Users\\Pying\\Downloads\\mallet\\mallet-2.0.8\\bin\\mallet'
ldamallet = gensim.models.wrappers.LdaMallet(mallet_path, corpus=corpus, num_topics=15, id2word=id2word)

报错如下：

AttributeError                            Traceback (most recent call last)
<ipython-input-14-e1a0fe67b1a6> in <module>
      6 
      7 mallet_path = 'C:\\Users\\Pying\\Downloads\\mallet\\mallet-2.0.8\\bin\\mallet'
----> 8 ldamallet = gensim.models.wrappers.LdaMallet(mallet_path, corpus=corpus, num_topics=15, id2word=id2word)

AttributeError: module 'gensim.models' has no attribute 'wrappers'

module 'gensim.models' has no attribute 'wrappers'，找不到wrappers，是不是版本不对哦。

虽然没用过，但猜测是导包的问题，可以试下这样

import gensim
# 加个导包
import gensim.models  
import gensim.corpora as corpora
from gensim.utils import simple_preprocess
from gensim.models import CoherenceModel
import os

os.environ.update({'MALLET_HOME': r'C:/Users/Pying/Downloads/mallet/mallet-2.0.8/'})
mallet_path = 'C:\\Users\\Pying\\Downloads\\mallet\\mallet-2.0.8\\bin\\mallet'
ldamallet = gensim.models.wrappers.LdaMallet(mallet_path, corpus=corpus, num_topics=15, id2word=id2word)

你好，为什么我gensim的版本是3.8.3也显示

module 'gensim.models' has no attribute 'wrappers'

AttributeError                            Traceback (most recent call last)
<ipython-input-48-4a38cb36c801> in <module>
      1 import gensim.models
      2 mallet_path = 'path/to/mallet-2.0.8/bin/mallet' # update this path
----> 3 ldamallet = gensim.models.wrappers.LdaMallet(mallet_path, corpus=corpus, num_topics=20, id2word=id2word)

AttributeError: module 'gensim.models' has no attribute 'wrappers'
