Still this bug did not been solved in version 1.0
Hope streamlit creators take care of it in order to take benefetis of the version 1.0 features.
I am also experiencing this issue. Rolled back to .84 but I actually also need session states, so this kinda sucks.
Yes youāre right this is sucks because there are a lot of new features in the latest version that can be very useful.
Hope that this issue is being debugued by streamlitās creators

Dear users,
If the workaround proposed above didnāt solve your issue, please use the approach described here.
This allows you to continue upgrading to the latest version of Streamlit and getting all the latest goodies!
Sorry for the inconvenience! Weāre waiting for Arrow to fix this issue.
I tried to add this line is the config.toml but when i tried to run streamlit app it crash and display the below error:

It looks like it canāt parse the config.toml file.
Can you post the contents of the file? Iāll be happy to help you resolve it!
P.S. Or you can open an issue on GitHub if you like.
this is the content of the file without adding the line that you suggested before.

I donāt get any errors when I use that TOML file. Can you please post the version of the config.toml that produces the error?
Thank you!
I did not understand what you mean by the version of config.toml.
Each time i try to create the file by typing this statement streamlit config show > ~/.streamlit/config.toml than try to run the app the system crash and display the error that i showed above.
Based on this post everyone has delete the config file and everything work again.
How to fix this because i am stuck in the old version of streamlit. v 0.84
I see. There might be an issue with Windows. Letās get your app running first, and then weāll 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.
i did upgrade to the latest version and rerun the command it works
but when i added the line to the config.toml file it crash and display the below error:

Hi @thiago , I added [global]
dataFrameSerialization = ālegacyā 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. Iām 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 donāt have to use legacy serialization anymore.
