After upgrade to the latest version now this error id showing up **ArrowInvalid**

Using Streamlit

I see. There might be an issue with Windows. Let’s get your app running first, and then we’ll fix the issue with the configuration file.

Try running your script with

streamlit run app.py --global.dataFrameSerialization="legacy"

I tried you suggestion but the system crash and display the below error:

(AIenv) PS F:\AIenv\streamlit> streamlit run app2.py --global.dataFrameSerialization="legacy"
Usage: streamlit run [OPTIONS] TARGET [ARGS]...
Try 'streamlit run --help' for help.

Error: no such option: --global.dataFrameSerialization

What version of streamlit are you using? That config option is only available after 0.85. Try upgrading to the latest version and rerunning the command.

All you have to do is to put the following line before printing out
df = df.astype(str)
st.dataframe(df)
good luck

Hi @thiago , I added [global]
dataFrameSerialization = “legacy” to config.toml file and issue was resolved for local
but while hosting the app from GitHub on share.streamlit.io the issue is still persistent. Not able to read the config file or is there a way around for while hosting the app. I’m using the same code that runs well on local.

@Deepansh_Soni we have implemented a few fixes on the problem with the arrow serialization which will be released with the upcoming version (1.14). I assume this will resolve your problem with arrow, so you don’t have to use legacy serialization anymore.
