How to write geopandas data into osm.pbf file using python?

Question

I have sample nodes, edges data like below. I am using ElementTree to write the data into .osm file and then trying to convert into .osm.pbf using osmosis but when trying to convert from .osm to .osm.pbf osmosis throws error saying "osm format is not not supported" .Is my output format worng? Also this process is very slow,time consuming and not cost effiecnt. Is there any library that converts geopandas node,edges data into .osm.pbf? What is the best way to convert geopandas(nodes,edges) data into .osm.pbf file?
