想要用python画股票K线图，但是代码运营的时候却报错，难道不能用index.to_pydatatime吗？ 求大神解决！
代码如下：
import mpl_finance as mpf
from pandas.plotting import register_matplotlib_converters
register_matplotlib_converters()
fig, (ax1, ax2) = plt.subplots(2,1, sharex=True)
mpf.candlestick_ohlc(ax1, zip(dates.date2num(stock_data.index.to_pydatetime()),
stock_data['open'], stock_data['high'],
stock_data['low'], stock_data['close']),
width=0.8, colorup='g', colordown='r')
报错如下：
An exception has occurred, use %tb to see the full traceback.
SystemExit: usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
