Hi Vikas,
Thanks for sharing. I´ve tried to use this feature to groupby a transaction file, in order to get only 1 occurence of each item.
I´m using ExecuteStreamCommand (better for pandas) insted of ExecuteScript) and getting an errro "ModuleNotFoundError: No module named 'pandas'.
I´m using an Ubuntu machine with python and pandas installed.

It would have been really good if you could have shown with FlowFile as direct input to Python instead of stdin because this approach eliminates FlowFile attributes that were preserved before ingesting to script.

Hello Vikas .I followed same approach but I am getting error -->permission denied in case of execute sream command. I tried giving permissions to python file using chmod -R 777 ,Chmod +x ..but my error is not resolved.I am using ubuntu os.
could you please in resolving my issue.Thanks in advance.

can the executeStreamCommand accept multiple flowfiles? For eg if i want to do merge on a common column in 2 flow files , is that possible?

I just tried this, but it is throwing error as "%1 is not a Win32 application". I am having a doubt on the nifi directory and the python installation directory. How about these two relationship?

Thank you for the video! I have a question.

I just need to make a script that should perform massive preprocessing operations, and then take in the stream files.
As I understand it, for each stream file the script will be run every time. This is true?
Can I make a python script that starts once and receives stream files many times.

Hi Vikas ,I tried running a shell script instead of a python script but I am getting the error "Not a directory : error code 20 " . I have given the script path in the properties.

hi Vikas : Does it integrate with Pytorch ?
