6 years ago Hi, I'm developing a different way of storing the data, in HDF5 format. Along the way I made many other changes too, like tightly type-casting all the defined GTFS fields as either string or number. So there will be changes soon. At present I've changed some of the functions but many of the other functions are breaking and need work, so I haven't put the changed code up on github yet (how does one push a folder from ubuntu terminal as a development branch?). But can you share the column and the values that made this error happen?
Here's the type-casting:
GTFS_dtypes= {
'route_id':'str', 'route_short_name':'str', 'route_long_name':'str', 'route_text_color':'str', 'route_color' :'str', #routes
'stop_id':'str', 'zone_id':'str', 'stop_name':'str', #stops
'trip_id' :'str', 'block_id':'str', 'trip_headsign':'str', 'direction_id':'int64', #trips
'trans_id':'str', 'translation':'str', #translations
'agency_id':'str', 'agency_name':'str', 'agency_timezone':'str', 'agency_url':'str', #agency
'shape_id':'str', 'shape_pt_lat':'float64', 'shape_pt_lon':'float64', 'shape_pt_sequence':'int64', #shapes
'arrival_time':'str', 'departure_time':'str', 'stop_sequence':'int64', 'stop_headsign':'str', 'timepoint':'int64', 'pickup_type':'int64', 'drop_off_type':'int64', #stop_times
'service_id':'str', 'monday':'int64', 'tuesday':'int64', 'wednesday':'int64', 'thursday':'int64','friday':'int64', 'saturday':'int64', 'sunday':'int64', 'start_date':'str', 'end_date':'str', #calendar
'fare_id':'str', 'price':'float64', 'currency_type':'str', 'payment_method':'int64', 'transfers':'int64', #fare-attributes
'origin_id':'str', 'destination_id':'str', 'contains_id':'str' #fare-rules
}

I was trying to upload an existing feed and ran into the error below. There is a numpy int64 type which is not directly serializable to JSON.
A fix appears to be here. https://stackoverflow.com/questions/27050108/convert-numpy-type-to-python/27050186#27050186
