收到错误“TypeError：得到了意外的关键字参数”但参数在函数定义中

问题描述

我有一个定义如下的函数：

import yfinance
from retry import retry

@retry(tries=3,delay=5)
def get_yfinance(tickers,start=None,end=None,interval='1h'):
    logging.info(f'Downloading data for {len(tickers)}')
    ticker_string = ' '.join(tickers)
    df = yfinance.download(ticker_string,group_by = 'ticker',interval=interval,start=start,end=end,prepost=True)
    df2 = df.stack(level=0).rename_axis(['Date','Ticker']).reset_index(level=1)
    df2['Date'] = df2['Date'].dt.tz_convert('UTC')
    df2 = df2.rename(columns={'Adj Close': 'AdjClose'})
    logging.info(f'Returned df with shape {df2.shape}')
    return df2

当我尝试这样称呼它时：

etlts = datetime.Now()
start = etlts - timedelta(hours=1)
tickers = sidf['Ticker'].to_list()
ydf = get_yfinance(tickers,end=etlts,interval='1m')

我得到以下堆栈跟踪：

   3053                         arg=next(iter(kwargs))))

TypeError: got an unexpected keyword argument 'interval'

任何参数组合都会发生这种情况。无论我保留还是删除 @retry 装饰器，都会发生这种情况。我很感激任何帮助。
