Fiona的架构问题

Question

我最近收到了“ValueError: Record does not match collection schema:”错误。我一直在使用

form fiona import collection
form shapely.geometry import mapping, shape 
with collection(path_in, "r") as input:
    schema = input.schema.copy()
    with collection(path_out, "w", "ESRI Shapefile", schema) as output:
        list = []
        for f in input:
            list.append(shape(f['geometry']))
    do stuff with shapely 
    output.write({'geometry': mapping(somethingIDid), 'properties':{'somethingFromSchema':'somethingToMakeThisValid'}})

我以为我是从输入文件中提取模式，所以我写的记录应该与原始模式匹配。对？是否有更好的方式与身材匀称？
