如何在與 web.DataReader 相關的 Python 中修復此錯誤

Question

我有一個與 web.datareader 相關的錯誤。 出於某種原因，我無法弄清楚是什么原因造成的。 有任何想法嗎？

!pip install mplfinance
!pip install seaborn
!pip install matplotlib

import numpy as np
import pandas as pd
import mplfinance as mpf
import datetime as dt
import matplotlib.pyplot as plt
import seaborn as sns

currency = "USD"
metric = "Close"

start = dt.datetime(2018,1,1)
end = dt.datetime.now()

crypto = ['BTC', 'ETH', 'LTC', 'XRP', 'DASH', 'SC']
colnames = []

first = True

for ticker in crypto:
    data = web.DataReader(f"{ticker}-{currency}", "yahoo", start, end)
    if first:
        combined = data[[metric]].copy()
        colnames.append(ticker)
        combined.columns = colnames
        first = False
    else:
        combined = combined.join(data[metric])
        colnames.append(ticker)
        combined.columns = colnames

plt.yscale('log') # first show linear

for ticker in crypto:
    plt.plot(combined[ticker], label=ticker)

plt.legend(loc="upper right")

plt.show()

# # Correlation Heat Map

print(combined)

combined = combined.pct_change().corr(method='pearson')

sns.heatmap(combined, annot=True, cmap="coolwarm")
plt.show()

您缺少兩行：
