Python output read the wrong way on the output.

[afostor]

I checked my output dataframe in Python formula before the dataiku.Dataset("output_dataset").write_with_schema(df) command. But, when I check the output dataset, it ommits some rows and fill them with duplicates. What could have happended?

Hi, 

This type of issue can be due to an unsupported version of pandas being used in your code env. 

Can you please confirm the exact Python version you are using and the pandas version? You can quickly check by running :

import pandas as pd
from platform import python_version

print(python_version())
print(pd.show_versions())

You should be using one of the Pandas versions available for your Code env -> Packages to install -> Core package versions:

These are my versions and, as I can observe, they match with the ones supported by Dataiku .

However, I changed my entire environment for another configured and it worked. I think maybe other libraries are not according to the Dataiku functionalities.

Thanks
