The answers on this site mostly suggest using bzip2 and bunzip, but I can't install them in Google Collab.
You can run external commands (shell commands) by prepending them with a
bunzip2 are standard Linux commands and should be pre-installed and available to you.
[ ] !bunzip2 path/to/myfile.bz2
[ ] !bzip2 -d path/to/myfile.bz2
If that doesn't work, you can then use Python code to access the file, in which case the bz2 module will be helpful.
[ ] import bz2, shutil with bz2.BZ2File('path/to/compressed.bz2') as in: with open('path/to/uncompressed', 'w') as out: shutil.copyfileobj(in, out)
