I have changed my code same as the test code and referring to “row_id”. However I am still getting the same error message. Can you check if there is any other issue here? I mean, data type of the row id or something else.
Yes the output file format generated by your code is wrong.
prob_approval need to be float instead of arr[float]. Shared the current output in above link as comment.
Thank you. It is working fine now.
