在 Python 中使用 Alpha Vantage 编写简单的股票预测服务。我收到这个错误

Question

这是简单打印股票预测的程序...

  from alpha_vantage.timeseries import TimeSeries
    # Your key here
    key = 'yourkeyhere'
    ts = TimeSeries(key)
    aapl, meta = ts.get_daily(symbol='AAPL')
    print(aapl['2020-22-5'])

我收到这个错误...

Traceback (most recent call last):
  File "C:/Users/PycharmProjects/AlphaVantageTest/AlphaVantageTest.py", line 7, in <module>
    print(aapl['2020-22-5'])
KeyError: '2020-22-5'

由于那没有用，我尝试了更多的技术知识...

from alpha_vantage.timeseries import TimeSeries
from alpha_vantage.techindicators import TechIndicators
from matplotlib.pyplot import figure
import matplotlib.pyplot as plt

# Your key here
key = 'W01B6S3ALTS82VRF'
# Chose your output format, or default to JSON (python dict)
ts = TimeSeries(key, output_format='pandas')
ti = TechIndicators(key)

# Get the data, returns a tuple
# aapl_data is a pandas dataframe, aapl_meta_data is a dict
aapl_data, aapl_meta_data = ts.get_daily(symbol='AAPL')
# aapl_sma is a dict, aapl_meta_sma also a dict
aapl_sma, aapl_meta_sma = ti.get_sma(symbol='AAPL')


# Visualization
figure(num=None, figsize=(15, 6), dpi=80, facecolor='w', edgecolor='k')
aapl_data['4. close'].plot()
plt.tight_layout()
plt.grid()
plt.show()

我收到这些错误...

Traceback (most recent call last):
  File "C:/Users/PycharmProjects/AlphaVantageTest/AlphaVantageTest.py", line 9, in <module>
    ts = TimeSeries(key, output_format='pandas')
  File "C:\Users\PycharmProjects\AlphaVantageTest\venv\lib\site-packages\alpha_vantage\alphavantage.py", line 66, in __init__
    raise ValueError("The pandas library was not found, therefore can "
ValueError: The pandas library was not found, therefore can not be used as an output format, please install manually

如何改进我的程序，以免收到这些错误？ None 这些程序的语法很糟糕。感谢任何可以提供帮助的人。

Answer 1

您需要安装 pandas。如果你只是使用 pip，你可以运行 pip install pandas 如果你使用 conda 来管理你的环境，你可以使用 conda install pandas.
