ValueError when I use DataFrame data for st.radio button

[choies1]

I meet the following error: ValueError(“{} is not in iterable”.format(str(x))).

[My code]
import streamlit as st
import pandas as pd

dict_data = {‘A’: [‘dog’, ‘cat’, ‘bird’], ‘B’: [1, 2, 3],}
df = pd.DataFrame(dict_data)
st.radio(‘DataFrame data’, df)

Hi @choies1

I suspect you’re using an older version of the Streamlit library. You can check what version you’re using by running the following in your terminal:

streamlit version

Your code snippet runs without issues on Streamlit 1.9.0:

I would suggest upgrading to the latest Streamlit version:

Happy Streamlit-ing!

I tested it on windows 11. My streamlit version is 1.9.0 and python version is 3.9.7.

I still have the same problem. What should I check?

[snehankekre]

I would start by including the following line before you define the dataframe:

st.write(st.__version__)

As a sanity check, that will display the version of the Streamlit your app is running on. I suspect you have multiple conda environments with different versions of Streamlit. The environment with which you run streamlit run might not be the same one when you check your Streamlit version.

I recommend going through our installation instructions for Windows to set up a clean environment.

Hi @choies1

Please disregard my reply about Streamlit versions. I now understand your issue: while you’re able to select the options via radio buttons, the ValueError: dog is not in iterable appears in your terminal. This occurs even though the frontend does not raise any errors!

I believe you’ve discovered a bug . You can report the bug by creating a new issue in our GitHub repo and our engineers will work on a fix. Thank you for brining this to our attention! I’ve filed an internal bug report.
