Python psycopg2.InternalError:分析错误-无效几何体

我们正在尝试使用Python将多重字符串插入到PostgreSQL数据库中。我们正在使用

ppygis

将坐标转换为实际几何图形。支架是要插入的坐标。名单的格式如下：

        x = float(stand[1].split(' ')[0])
        y = float(stand[1].split(' ')[1])
        coordinate = ppygis.Point(x, y)
        coordinate.srid = SRID_WGS84
        # Stand delimiters
        delimiter = []
        line = []

        for i in range(2, len(stand)):
            # The cycle will run through everythin in the stand list
            # But it will only actually do something when it finds a coordinate
            # counter
            if (len(stand[i].split(' ')) == 1):
                # Number of coordinates to process. Adjusted for indexation
                ncoords = int(stand[i]) + 1

                for c in range(i + 1, i + ncoords, 1):
                    x = float(stand[c].split(' ')[0])
                    y = float(stand[c].split(' ')[1])

                    point = ppygis.Point(x, y)
                    point.srid = SRID_WGS84
                    line.append(point)
                line = ppygis.LineString((line))
                delimiter.append(line)
                line = []
        delimiter = ppygis.MultiLineString((delimiter))
        cur.execute("""
                INSERT INTO taxi_stands(id, name, coordinates, delimiter_geom)
                VALUES(%s, %s, ST_PointFromText(%s), %s);
                """, (taxi_stands_list.index(stand), stand_name, coordinate,
                    delimiter))

插入数据库时，我们会遇到以下错误：

[nº of points in line, x1line1, y1line1, ..., nº of points in line, ...]

提示：“0101000020E61000645D”不要使用，因为您的几何图形已处于格式（ST_PointFromText要求几何图形处于格式）

只需更改您的声明，以便：
