Can't open *.7z extension on CentOs

[leojoubert]

Hi,

I have this code, that work perfectly find in Ubuntu 18.04 :

from mw import xml_dump

# For instance, with frwiki dump in 7z format
files = ["examples/dump.xml.7z"]

def page_info(dump, path):
    for page in dump:

        yield page.id, page.namespace, page.title


for page_id, page_namespace, page_title in xml_dump.map(files, page_info):
    print(" ".join([str(page_id), str(page_namespace), page_title]))

That don't work anymore when I am going to CentOs in my lab.

This problem is solved when I take my dump into XML or even BZ2 format. This tuhs is not a solution for me : given files are much too heavy. I would really need to have 7z format available.
