使用 python 比特幣庫在測試網上發送比特幣時無法發送錯誤

當我執行腳本時

from bitcoin.core import COIN, b2lx
import bitcoin.wallet
import bitcoin.rpc

rpc = bitcoin.rpc.Proxy()
addr = bitcoin.wallet.CBitcoinAddress('mfrMeTKojpEXFXpcQiRr7zA3Bff4UBgZTx')

txid = rpc.sendtoaddress(addr, 0.001 * COIN)
print(b2lx(txid))

我收到以下錯誤

知道如何解決這個問題嗎？我使用的程式碼來自

範例文章

問題是addr提供的地址無效 - 主網地址在測試網上不起作用，反之亦然。（從編輯修訂歷史中，您提供的程式碼範例正在使用bitcoin.wallet.CBitcoinAddress('1JwSSubhmg6iPtRjtyqhUYYH7bZg3Lfy1T')它將提供一個主網路地址）

將變數中提供的地址替換為addr合法的測試網路地址，它應該可以工作。
