我使用Pycharm编写代码。
代码语言：javascript运行复制import importlib,sys
importlib.reload(sys)
from snownlp import SnowNLP
import pandas as pd
text=pd.read_excel(u'comment-label.xlsx',header=0) #读取excel表格数据
text0=text.iloc[:,0] #提取所有数据
text1=[i.decode('utf-8')for i in text0] #转码
sent=[SnowNLP(i).sentiments for i in text1] #遍历每条评论进行预测
newsenti=[]
for i in sent:
if(i>=0.5):
newsenti.append(1)
else:
newsenti.append(-1)
text['predict'] = newsenti
counts=0
for j in range(len(text.iloc[:,0])): #遍历所有标签，将预测标签和实际标签进行比较，相同则判断正确。
if text.iloc[j,2]==text.iloc[j,1]:
counts+=1
print (u"准确率为:%f"%(float(counts)/float(len(text)))) #输出本次预测的准确率并返回错误

from snownlp import SnowNLP
ImportError: cannot import name 'SnowNLP'
Process finished with exit code 1但是我已经安装了'snownlp‘'snownlp ' installing path 包
昨天我可以用from snownlp import SnowNLP很好地调试其他代码，没有看到这个错误，但现在其他代码也遇到了同样的错误。
我在Pycharm中重新安装了snownlp包，但它不起作用。
我该怎么做呢？
