python - 访问 FRED 时 panda DataReader 失败

Question

我创建了一个库：

def GDP_SP500() :
    # import relevant modules
    import pandas_datareader.data as pdr
    import datetime
    # define datetimes for start and end dates
    start_date = datetime.datetime(2011, 2, 1)
    end_date = datetime.datetime(2021, 9, 29)

    SP500_10yrtreasury = pdr.DataReader(["SP500","DGS10"],'fred',start_date,end_date)
    SP500_10yrtreasury.plot(title = 'S&P 500 compared to 10yr Treasury Yield', 
                            secondary_y = "DGS10", figsize=(15, 6))
    print('Done')
    return
if __name__ == '__main__':
    vix()
    TreasuryYieldsPlot()
    GDP_SP500()

作为一个独立的，它会执行（有时），但作为另一个 python 3.8 程序的库调用，它总是失败，需要重新启动 spyder 5.0.5 错误是：

Exception in thread Exception in thread Thread-12Thread-11:

我正在运行 python 3.8 和 anaconda navigator 2.0.4 两种执行方式似乎都没有一致的结果。有错误：

Traceback (most recent call last):
Traceback (most recent call last):
  File "C:\Users\monro\anaconda3\lib\threading.py", line 932, in _bootstrap_inner

  File "C:\Users\monro\anaconda3\lib\threading.py", line 870, in run
  File "C:\Users\monro\anaconda3\lib\threading.py", line 870, in run

这里发生了什么？？
