大佬萌 我在用gensim库中的Word2Vec函数时为什么会对size=50报错 部分代码和错误提示放在下面了

import gensim #文本分类库
from gensim.models import Word2Vec
from gensim.models.word2vec import LineSentence

def train_w2v_model(path):
    w2v_model = Word2Vec(LineSentence(path), workers=4, size=50, min_count=1)
    w2v_model.save('w2v.model')
    #w2v.model.wv.save('w2v.model')

#错误提示

----> 9 w2v_model = word2vec.Word2Vec(LineSentence(path), workers=4, size=50, min_count=1)
10 w2v_model.save('w2v.model')
11 #w2v.model.wv.save('w2v.model')
TypeError: __init__() got an unexpected keyword argument 'size'
