流光事件循环

Question

，这是我第一次使用Streamlit。我正在尝试将我的python脚本放到一个交互式GUI中。

import streamlit as st 
import pandas as pd 
import plotly.express as px 
import datetime
from terra_sdk.client.lcd import LCDClient

date = datetime.datetime.now()
today = date.strftime("%B_%d_%Y")
st.set_page_config(page_title="Terra Luna Balance Updater",
                   page_icon=":bar_chart",
                   layout="wide"
)


uploaded_file = st.file_uploader('Upload your text/csv file here')

if uploaded_file:
    st.header('Terra Luna Statistics')
    df = pd.read_csv(uploaded_file)
    st.table(df)

，我用一个普通的python脚本测试了它，它运行得很好。

def main():
    terra = LCDClient(url="https://lcd.terra.dev", chain_id="columbus-5")
    Wallet_Address=(df.loc[:,'Address'])
    Balance_storage = []

    for address in Wallet_Address:
        balance_array = terra.bank.balance(address)
        balance = balance_array[1]['total']
        Balance_storage.append(balance)

        df[today] = Balance_storage
        
        df.to_csv(uploaded_file, index=False)
        
if st.button('Click me'): 
    main()

单击按钮后，我将得到一个错误：

线程'ScriptRunner.scriptThread‘中没有当前事件循环。在get_event_loop引发RuntimeError中(‘线程%r中没有当前事件循环’

。

我看不出密码有什么问题。问题的原因可能是流光的版本。

另外，您也可以检查这个：RuntimeError: There is no current event loop in thread 'ScriptRunner.scriptThread'
