Connecting and accessing data from influxdb(self hosted server) to jupyter notebook

Question

I have been trying to access influxdb self hosted data through jupyter notebook. ref link: https://www.influxdata.com/blog/streaming-time-series-with-jupyter-and-influxdb/ . from influxdb import InfluxDBClient from datetime import datetime import os

from influxdb_client import InfluxDBClient, Point, WritePrecision from influxdb_client.client.write_api import SYNCHRONOUS client= InfluxDBClient(url="", token=token, org=org,bucket=bucket,host=influxdb_host)

Code has been sucessfully executed upto here and i have been trying the next step suggested in the ref link and have been getting an import error for stream although i have sucessfully imported hvplot.

def source_data(auto_refresh: int, query: str, sink: Stream):
    rx \
        .interval(period=timedelta(seconds=auto_refresh)) \
        .pipe(ops.map(lambda start: f'from(bucket: "my-bucket") '
                                    f'|> range(start: -{auto_refresh}s, stop: now()) '
                                    f'{query}')) \
        .pipe(ops.map(lambda query: client.query_api().query_data_frame(query, data_frame_index=['_time']))) \
        .pipe(ops.map(lambda data_frame: data_frame.drop(columns=['result', 'table']))) \
        .subscribe(observer=lambda data_frame: sink.emit(data_frame), on_error=lambda error: print(error))
    pass

Is this the right way to extract the self hosted data to jupyter notebook ? or have I been looking into the wrong references.

Please suggest any reference links to extract selfhosted data from influx db to jupyter notebook.
