Errors after deploying the app

[Kasra]

Hi
I created my first app using streamlit. It works without any errors in my own pc (Python 3.9.7) but when I deploy it on streamlit cloud (Python 3.9) I get this error:

AttributeError: 'DataFrameGroupBy' object has no attribute 'value_counts'

The line which this error refers to is:

df_grouped = df.groupby(by=[groupby_column], as_index=False).value_counts()

I even tried running the app on ngrok and again get this error. I changed the pandas version to 1.0.5 in requirements.txt and rebooted the app but still it doesn’t work.
I really can’t understand why it doesn’t work on cloud while it perfectly runs on windows!

Hi @Kasra, welcome to the Streamlit community!

Can you post a link to the repo that you are deploying from?

Best,
Randy

Hi @Kasra

You’ll notice in the pandas docs that version 1.0.5 of pandas does not contain a DataFrameGroupBy.value_counts method. It was added in later versions. For example, version 1.4.1 does contain a DataFrameGroupBy.value_counts method.

Pinning a pandas version in requirements.txt that supports the method should fix the issue.

pandas==1.4.1

Thank you dear Snehan.
I did it and the result was these errors:

Please ensure you have selected Python 3.8 or Python 3.9 while deploying your app on Streamlit Cloud. Pandas version 1.4.1 isn’t available for Python 3.7.
