Streamlit学习笔记(2)

使用 supervisor 部署 streamlit app

创建文件 /etc/supervisor/conf.d/streamlitAPP.conf

[program:streamlitAPP]
command = /home/username/miniconda3/bin/streamlit run /path2/app.py
directory = /home/username
autostart = true
startsecs = 20
autorestart = true
startretries = 3
user = username
environment = STNORESTART="1", HOME="/home/username"

开始运行:

添加:
sudo supervisorctl update
启动
supervisorctl start streamlitAPP
重启
supervisorctl restart streamlitAPP
停止
supervisorctl stop streamlitAPP

Streamlit 中调用 pyecharts

示例: 画K线图

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

# pip install pyecharts
from pyecharts.charts import Kline
# pip install streamlit-echarts
from streamlit_echarts import st_pyecharts
