python运行出现错误 非常感谢!

data_date = data.groupby('date')['clk'].agg({
'展示量':'count',
'点击量':sum,
'点击率':np.mean
})

建立《2017/05/05至2017/05/13的广告点击情况》的柱形-折线图

from pyecharts import options as opts
from pyecharts.charts import Bar, Line
from pyecharts.faker import Faker

name = data_date.index.tolist()
v1 = data_date.展示量.tolist()
v2 = data_date.点击量.tolist()
v3 = ((data_date.点击率.values)*100).tolist()
v3 = [round(i,2) for i in v3]

bar = (
Bar(init_opts=opts.InitOpts(width="680px", height="420px"))
.add_xaxis(name)
.add_yaxis("展示量", v1)
.add_yaxis("点击量", v2)
.extend_axis(
yaxis=opts.AxisOpts(axislabel_opts=opts.LabelOpts(formatter="{value} %"), interval=1)
)
.set_series_opts(label_opts=opts.LabelOpts(is_show=True))
.set_global_opts(
title_opts=opts.TitleOpts(title="2017/05/05至2017/05/13的广告点击情况",pos_left="18%"),
yaxis_opts=opts.AxisOpts(axislabel_opts=opts.LabelOpts(formatter="{value} "), max_=350000),
legend_opts=opts.LegendOpts(pos_top="10%", pos_right="10%")
)

)

line = Line().add_xaxis(name).add_yaxis("点击率", v3, yaxis_index=1)
bar.overlap(Iine)
bar.render_notebook()

然后在jupter上面运行此代码后显示错误,下面是系统显示的完整的错误原因。希望大家可以帮我看一下,百度后还是没有解决。
