json2shapes function results in segmentation fault #19

Closed askonivala closed 3 years ago

askonivala commented 3 years ago

This code:

query = '[out:json]; way[wikidata="Q420810"]; out geom;'
result = osm2geojson.overpass_call(query)
json_dict = json.loads(result)
geo_json = osm2geojson.json2shapes(json_dict)

Results in:

I tested your example and received correct geometry. I think problem with shapely (it uses c extensions). Can you try to reinstall shapely conda install shapely --force-reinstall?

Thanks a lot! Yes, the shapely installation in my virtual environment is indeed broken. Sorry about this, I should have understood that from the debug message.
