Python BZ2 IOError: invalid data stream

Question

Traceback (most recent call last):
  File "TTRC_main.py", line 309, in <module>
    updater.start()
  File "TTRC_main.py", line 36, in start
    newFileData = bz2.BZ2File("C:/Program Files (x86)/Toontown Rewritten/temp/phase_7.mf.bz2"," rb").read()
IOError: invalid data stream

The code to retrieve file I'm getting that's giving me this error is:

newFileComp = urllib.URLopener()
newFileComp.retrieve("http://kcmo-1.download.toontownrewritten.com/content/phase_7.mf.bz2", "C:/Program Files (x86)/Toontown Rewritten/temp/phase_7.mf.bz2")

What do I do to fix this error? Its not really descriptive. (to me)

Answer 1

Could the issue be occuring because of the extra spacein the file mode? -

newFileData = bz2.BZ2File("C:/Program Files (x86)/Toontown Rewritten/temp/phase_7.mf.bz2"," rb").read()

Try this -

newFileData = bz2.BZ2File("C:/Program Files (x86)/Toontown Rewritten/temp/phase_7.mf.bz2","rb").read()

Answer 2

1. Make sure file is bz2 format.
2. Make sure the read and write actions are the same "r","w" or "rb","wb"
3. Like Anand said, no space in "rb".

Answer 3

For me the issue was that the files were not in .bz2 format.
