Can someone help me with the error.

I am getting the error :

File “script.py”, line 29

^

SyntaxError: unexpected EOF while parsing

for the code

from nltk import RegexpParser

from pos_tagged_oz import pos_tagged_oz

from np_chunk_counter import np_chunk_counter

define noun-phrase chunk grammar here

chunk_grammar = “NP: {

?*}”

create RegexpParser object here

chunk_parser = RegexpParser(“NP: {

?*}”)

create a list to hold noun-phrase chunked sentences

np_chunked_oz = list()

create a for loop through each pos-tagged sentence in pos_tagged_oz here

for pos_tagged_sentence in pos_tokenized_oz:

np_chunked_oz.append(chunk_parser.parse(pos_tagged_sentence)

Hello. While I was doing the exercise I started getting this error. I didn’t change anything from the console or other files in the workplace. Is this a bug? As it throws an error in the part where the files are imported, a code of which was already written by Codeacademy, I am not sure how can I fix it.

Traceback (most recent call last):
File “script.py”, line 2, in
from pos_tagged_oz import pos_tagged_oz
File “/home/ccuser/workspace/nlp-regex-np-chunking/pos_tagged_oz.py”, line 4, in
pos_tagged_oz = pickle.load(picklefile)
_pickle.UnpicklingError: invalid load key, ‘\xef’.
