RC_7_3 無法執行 #19

RC_7_3: 上網抓資料並畫K線圖

執行到 quotes = quotes_historical_yahoo_ohlc('AAPL', start, end) 一直出現URLError: <urlopen error [Errno 11001] getaddrinfo failed>， 請問是什麼問題 ?

letylin commented 7 years ago

你好: 我這裡確認網路正常下，執行是沒有錯誤，如下圖。 另外，請在windows的command視窗, 輸入conda list檢視matplotlib是否已安裝。 若沒有請command 視窗輸入pip matplotlib install, 確認有此套件後再執行

你好:

我確認有安裝此套件 matplotlib 2.0.2 np112py36_0

以下是執行的LOG:

請問你的程式碼可以貼上來給我測看看, 我這裡沒有問題的。

letylin commented 7 years ago

可能是系統, 軟體環境問題, 能否同一支程式, 在另一台電腦測試過是否也出現同樣問題。程式碼本身應沒有錯。

slinwu commented 7 years ago

我直接用你網路上的執行

RC_7_3: 上網抓資料並畫K線圖

import matplotlib.pyplot as plt from matplotlib.dates import DateFormatter from matplotlib.finance import quotes_historical_yahoo_ohlc, candlestick_ohlc

下載資料起迄日, 日期格式與股票代號

start = (2016, 4, 1) end = (2016, 4, 25) weekFormatter = DateFormatter('%b %d') # 例如, Jan 03 2016 quotes = quotes_historical_yahoo_ohlc('AAPL', start, end)

若抓取的資料是空字串則離開系統

if len(quotes) == 0: raise SystemExit

設定繪圖區域的格式化

fig, ax = plt.subplots() ax.xaxis_date() plt.setp(plt.gca().get_xticklabels(), rotation=45, horizontalalignment='right')

畫K線圖並顯示

candlestick_ohlc(ax, quotes, width=0.6) plt.show()

我這邊確定可以正常執行。你的anaconda是什麼版本?

letylin commented 7 years ago

你的作業系統與anaconda版本是?
