此matplotlib.finance.candlestick2_ochl代码会发生什么? [英] What happen with this matplotlib.finance.candlestick2_ochl code?

问题描述

不知道该错误. csv文件来自pd.datareader.但是我认为这与数据读取器无关.我使用的csv文件是在出口前完成的，它是完整的.我认为"candlestick2_ochl()"函数有问题

Have no idea about the error. The csv file is from pd.datareader. ButI think it's not about datareader. the csv file i used is exported mouths ago, and it's complete.I think it's something wrong with "candlestick2_ochl()" function

推荐答案

由于Yahoo更新了其API，因此它可能已损坏. pandas_datareader将不再起作用

It is probably broken since Yahoo has updated its API. pandas_datareader will not work any more

作为临时修复程序，您可以下载fix-yahoo-finance软件包以使其再次起作用.您应该可以通过pip安装此软件包，

As a temporary fix, you can download the fix-yahoo-finance package to get this to work again. You should be able to pip install this package,

pip install fix-yahoo-finance

然后只需导入fix-yahoo-finance并重新运行即可.

Then just import the fix-yahoo-finance and re-rerun.
