Re: [sumo-user] Netedit doesn't load .osm file correctly
The error messages suggest that you are deleting nan lines from a .net.xml file and then processing it with netconvert.
You should instead delete all nan lines (and only those) from the osm file and then import it anew.
Alternatively, use the latest development version of netconvert which can now deal with those 'nan's in osm.

I’ve written a script which deletes every nan line and it’s parent and I get this result:

I also tried changing nan to an integer, for example 5, this time the network imports as the first image that I have attached.

Your input contains plenty of invalid data (i.e. <tag k="maxspeed" v="nan" />)
If you remove all the "nan" lines, all edges are imported.

Hello,

After I download an osm file from open street map, edit and split the traffic network into smaller subnetworks, I save the subnetworks as .osm files, using osmnx and python. 

However when I use the netconvert function 

netconvert --osm-files map.osm --output-file map.net.xml

or

netconvert --osm-files map.osm --output-file map.net.xml --geometry.remove --roundabouts.guess --ramps.guess --junctions.join --tls.guess-signals --tls.discard-simple --tls.join

and I open the the .net.xml file on Netedit or Sumo-Gui, some roads doesn’t appear even though I’m confident that the file is alright because when I load the saved .osm file and plot it on python there is no problem. 

I also tried importing .osm directly using the import foreign network function, but I still have the same result.
