Hi ,

Good Evening!!

I am reading a pandas dataframe from dataiku dataset and filtering on county code == 'NA' but my dataframe is not returning any value.

Is there any workaround for this. Kindly help!

    This behavior is expected with Pandas.

    Starting with DSS 9.0.4 or later we added support for pandas parameters keep_default_na.

    Which would allow you to add keep_default=False to your get_dataframe() function to handle this situation.

    One possible workaround for the previous version would be:

    1) Export to CSV to a managed folder using the Visual Export recipe and read the CSV with pandas from the managed folder:

    Use sample code this works only with local filesystem managed folder :

    import dataiku
    import pandas as pd, numpy as np
    from dataiku import pandasutils as pdu
    # Read recipe inputs
    managed_folder = dataiku.Folder("D0gTVBY3")
    path = managed_folder.get_path()
    filename = "country_prepared.csv"
    filepath = path + "/" + filename
    df = pd.read_csv(filepath, keep_default_na=False)
