set_page_config() issue in Microsoft edge #9797
Description
Checklist
- I have searched the existing issues for similar issues.
- I added a very descriptive title to this issue.
- I have provided sufficient information below to help reproduce this issue.
Summary
Having muliple files in your app and importing them to the app.py page and then afterwards settings the set_page_config() casuses the set_page_config() to crash saying it has been called muliple times even when it haven't.
Error msg:
_StreamlitSetPageConfigMustBeFirstCommandError: set_page_config() can only be called once per app page, and must be called as the first Streamlit command in your script.
For more information refer to the docs.
Traceback:..._
So this will work
#app.py
import streamlit as st
st.set_page_config(page_title='Web App', layout="wide"
import page_somePage as pageSomePage
import page_otherPage as pageOtherPage
import page_thePage as pageThePage
import page_faq as pageFAQ
This will not work
import streamlit as st
import page_somePage as pageSomePage
import page_otherPage as pageOtherPage
import page_thePage as pageThePage
import page_faq as pageFAQ
st.set_page_config(page_title='Web App', layout="wide")
to me its seems like adding the other files where i have the import streamlit as st calls the set_page_config() even thought it not present in the file. So maybe that done under the hood.
The issues only happens in Microsoft Edge and not in the Chrome or Brave browser.
Reproducible Code Example
#THIS WILL WORK
# app.py
import streamlit as st
st.set_page_config(page_title='Web App', layout="wide")
import page_somePage as pageSomePage
import page_otherPage as pageOtherPage
import page_thePage as pageThePage
import page_faq as pageFAQ
st.sidebar.subheader('My app')
page_somePage = 'somePage'
page_otherPage = 'otherPage'
page_thePage = 'thePage'
page_faq = 'FAQ'
pageOptions = [page_somePage, page_otherPage, page_thePage, page_faq]
pageSelect = st.sidebar.selectbox('Select page', options=pageOptions)
st.sidebar.divider()
if pageSelect == page_somePage:
page_somePage.showPage()
if pageSelect == page_otherPage:
page_otherPage.showPage()
if pageSelect == page_thePage:
page_thePage.showPage()
if pageSelect == page_faq:
page_faq.showPage()
#page_somePage.py
