如何在与 web.DataReader 相关的 Python 中修复此错误

Question

我有一个与 web.datareader 相关的错误。 出于某种原因，我无法弄清楚是什么原因造成的。 有任何想法吗？

!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()
