can't run

[physicszq]

hi, I'am a newer in this, and I run the comm of "python2 ./tools/getROSbin.py 6.38.4 x86 /nova/bin/www www_binary" it feedback an error of " 'int' object has no attribute 'seek'" it seem that the argument of the function sqfs = PySquashfsImage.SquashFsImage(offset=SQFS_OFFSET) in get_binary(fwfd, path) , tools/getROSbin.py is wrong.
