NLTK 中的导入错误：无法导入名称兼容

Question

I am using 'nltk' installed by pip in my project. It works fine in local But when I tried to deploy in google appengine , It shows the Import error 'Cannot import name compat'. How to resolve it? Thanks in advance

update: the code

from nltk import word_tokenize, pos_tag, ne_chunk, tree2conlltags

sentence = "Hi , This week has been crazy. My report is on IBM. Can you give it a quick read and provide some feedback. She is in London. John  lives in New   York  and works for the European Union."

ne_tree = ne_chunk(pos_tag(word_tokenize(sentence)))
iob_tagged = tree2conlltags(ne_tree)
print iob_tagged
name = []
for chunk in iob_tagged:
    if chunk[2] != 'O':
        name.append(chunk[2])
    else:
        name.append(chunk[0])
print name

The error

Try and upgrading your ntlk package:

pip install --upgrade nltk
