You may need to obtain the PennTreebank parse trees before running test_phrase_grammar.py

Thank you a lot. And I thought I have downloaded the PTB like following: image But It seems that these data don't work, I'm confused. Can you tell me whether this file I have download through CSDN is right? And I have no membership in Treebank Official site, what should I do?
