初学python小白一枚，到分析数据一步还可以正常print，加上可视化就会报错，麻烦大神帮忙看看是什么问题导致，谢谢！
报错信息在截图，代码如下：
# encoding: utf-8

import requests
from bs4 import BeautifulSoup
import html5lib
from pyecharts.charts import Bar

ALL_DATA = []

def parse_page(url):
headers = {
   'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36',
   'Referer': 'http://www.weather.com.cn/forecast/'
}
response = requests.get(url,headers = headers)
text =response.content.decode('utf-8')
soup = BeautifulSoup(text,'html5lib')
conMidtab = soup.find('div',class_= 'conMidtab')
tables = conMidtab.find_all('table')
for table in tables:
   trs = table.find_all('tr')[2:]
   for index,tr in enumerate(trs):
         tds = tr.find_all('td')
         if index == 0:
            city_td = tds[1]
         else:
            city_td = tds[0]
         city = list(city_td.stripped_strings)[0]
         temp_td = tds[-2]
         min_temp = list(temp_td.stripped_strings)[0]
         ALL_DATA.append({"city":city,"min_temp":int(min_temp)})
         # print({"city":city,"min_temp":int(min_temp)})
def main():
urls = [
   'http://www.weather.com.cn/textFC/hb.shtml',
   'http://www.weather.com.cn/textFC/db.shtml',

   'http://www.weather.com.cn/textFC/xn.shtml',
   'http://www.weather.com.cn/textFC/gat.shtml'
]
for url in urls:
   parse_page(url)

# 分析数据
# 根据最低气温进行排序
ALL_DATA.sort(key = lambda data:data['min_temp'])
data = ALL_DATA[0:10]
cities = list(map(lambda x:x['city'],data))
temps = list(map(lambda x:x['min_temp'],data))

# 可视化
# pyecharts
chart = Bar("中国天气最低气温排行榜")
chart.add('',cities,temps)
chart.render('temperature.html')

if __name__ == '__main__':
main()

pyecharts版本问题，1.0+开始代码不向下兼容
两个解决方案
1.安装0.5+的pyecharts
2.改代码，参考DEMO http://gallery.pyecharts.org/#/Bar/bar_stack0
更详细的就去翻官方文档吧
1.0+: https://pyecharts.org/#/zh-cn/rectangular_charts?id=bar%ef%bc%9a%e6%9f%b1%e7%8a%b6%e5%9b%be%e6%9d%a1%e5%bd%a2%e5%9b%be
0.5+: https://05x-docs.pyecharts.org/#/zh-cn/charts_base?id=bar%ef%bc%88%e6%9f%b1%e7%8a%b6%e5%9b%be%e6%9d%a1%e5%bd%a2%e5%9b%be%ef%bc%89
