無法訪問 erc20token-sdk-python 庫中的 send_tokens 函式

我創建了合約並嘗試使用“erc20token-sdk-python”庫連接到乙太坊主網。當我嘗試將令牌從一個地址發送到另一個地址時，它顯示“ValueError：未找到匹配函式”。我究竟做錯了什麼？

import erc20token
import json
contract_abi = '[{"constant": "True","inputs": [],"name": "name","outputs": [{"name": "","type": "string"}],"payable": "False","type": "function"},{"constant": "True","inputs": [],"name": "decimals","outputs": [{"name": "","type": "uint8"}],"payable": "False","type": "function"},{"constant": "True","inputs": [{"name": "_owner","type": "address"}],"name": "balanceOf","outputs": [{"name": "balance","type": "uint256"}],"payable": "False","type": "function"},{"constant": "True","inputs": [],"name": "symbol","outputs": [{"name": "","type": "string"}],"payable": "False","type": "function"}]'

token_sdk = erc20token.SDK(provider_endpoint_uri='https://mainnet.infura.io/12345678',
                          private_key='private_key_here',
                          contract_address='0x818fc6c2ec5986bc6e2cbf00939d90556ab12ce5', 
                          contract_abi=json.loads(contract_abi),
                          gas_price=40, gas_limit=50000)
tx_id = token_sdk.send_tokens('address', 10)
print(tx_id)

錯誤日誌：

 tx_id = token_sdk.send_tokens('0xbeb6f3FBA63E462fDA138c67b4ADbAd416859b8f', 10)

您正在使用的 ABI 似乎缺少該transfer功能。

您可以在此處找到您正在使用的合約的完整 ABI：https ://etherscan.io/address/0x818fc6c2ec5986bc6e2cbf00939d90556ab12ce5#code 。
