[Streamlit 1.34] AttributeError: module 'streamlit.components' has no attribute 'v1'

• I have provided sufficient information below to help reproduce this issue.

Summary

Streamlit v1.34 seems to have removed v1 from streamlit.components, leading to an AttributeError when trying to use streamlit.components.v1.html().

There is no mention of any such change in the changelog, and the documentation still includes v1.html() in v1.34.0: https://docs.streamlit.io/develop/api-reference/custom-components/st.components.v1.html

streamlit.html() does not support all features supported by components.v1.html(), like height, and is not a good enough substitute yet.

Reproducible Code Example

import streamlit as st
st.components.v1.html()

Steps To Reproduce

1. Install Streamlit v1.34

pip install streamlit==1.34

2. Run the below code

import streamlit as st
st.components.v1.html()

Expected Behavior

v1.html() should be an attribute of streamlit.components

Current Behavior

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'streamlit.components' has no attribute 'v1'

Is this a regression?

• Yes, this used to work in a previous version.

Debug info

• Streamlit version: 1.34.0
• Python version: 3.8.15
• Operating System: Windows 11
• Browser: Edge

Additional Information

Using as streamlit._main._html() works.
Using as

from streamlit.components.v1 import html
html()

also works.

Hey @SiddhantSadangi , the docs state to import and use it like this

import streamlit as st
import streamlit.components.v1 as components

components.html("example")

This works for me in version 1.34. Are you able to confirm that it works if you use the import as stated in the docs?

[SiddhantSadangi]

Hey @raethlein
Thanks for the quick response!

Yes, it does work if imported as stated in the docs.

However, it'd be great if this change can be highlighted in the docs and the 1.34 changelog, as I have always been using it directly as streamlit.components.v1.html() with no issues until 1.34

You are welcome 🙂

I have also investigated a little bit why this changed and it seems to be that this should never have been possible, and was made transiently available via this import: from streamlit.components.v1.components import ComponentRegistry. If you check out an older Streamlit-version and run it in a normal Python shell, the import like that was not possible, likely because server.py is not imported in that case 🫠

There seem to be some places where we indeed advocate it like this: st.components.v1.html() and even though it looks like this was only possible due to some weird aspects of the Python import system, I am sorry to hear that this caused troubles on your side! I will check-in with the docs team about this!

That's weird 🫠

I get a different AttributeError on 1.34 (streamlit.components can be imported, but not components.v1)

And for some weird reason, it has stopped working for me with streamlit<1.34, with the same error as you see:

Anyway, I think you can close this issue and just vet any docs or marketing material referencing direct usage as streamlit.components.v1.html()

run command

pip install streamlit==1.32
