Invalid Argument error on the python code

I am beginner to python, and I have this code to decompress log file, but I have the error Invalid argument. I don't know why I got this error, in my opinion, I think it is because the log file is too big, cause I am scanning a log file which is 2gb file. But I have no idea how to fix the error. Please help, thank you. And below is my code with the error:

This is the error I got:
