我是Python的新手,我正在努力在matplotlib文档中运行这个示例:
http://matplotlib.org/examples/pylab_examples/finance_demo.html
我基本上是将代码1:1复制到我的Python文件中,当我试图运行它时,我得到了如下所示的错误:
File "plot.py", line 5, in <module>
from matplotlib.finance import quotes_historical_yahoo_ohlc, candlestick_ohlc
ImportError: cannot import name quotes_historical_yahoo_ohlc我在我的Mac和Linux机器上得到了相同的结果,所以我认为这与安装有关,或者它缺少一个依赖项。在Linux上我是通过apt-get install安装的,在Mac上我用的是pip。
任何帮助或故障排除信息都将不胜感激。

是的,我得到了同样的结果。
因此,在光标提示符下,我键入:
import matplotlib
dir(matplotlib.finance)除了末尾没有"_ohlc“之外,我看到了类似的项目。

'volume_overlay2', 'volume_overlay3', 'warnings']因此,我删除了最后五个字母_ohlc everywhere,看看会发生什么,现在它对我有效。但我不确定这是否真的是100%正确的。在2013年有一些@tcaswell的activity ...
