Getting the error when I try to evaluate quality, risk and safety metrics in Azure AI Studio.

Question

Getting error : "unsupported operand type(s) for +: 'NoneType' and 'NoneType'", when calculating quality, risk and safety metrics in Azure AI Studio. This worked fine until last week, facing errors from the previous 2-3 days.

Hello Kolla, Srinivasa Arudra Phani Bhushan

Thanks for reporting this issue, product team has acknowledged this issue and working on a fix. Will update here again if the issue has any progress.

At this moment, please try the workaround to disable tracing and redeploy the flow by setting the env var "PF_DISABLE_TRACING" to true, this can avoid the potential error.

os.environ['PF_DISABLE_TRACING'] = 'true'

I hope this helps!

Hello Kolla, Srinivasa Arudra Phani Bhushan,

Welcome to the Microsoft Q&A and thank you for posting your questions here.

I understand that you are having "unsupported operand type(s) for +: 'NoneType' and 'NoneType'", error.

The error message "unsupported operand type(s) for +: 'NoneType' and 'NoneType'" indicates that you’re trying to perform an addition operation on variables that are None, which typically means that the values you're working with haven't been properly initialized or calculated.

If a variable can legitimately be None, consider providing a default value such as:

   quality = quality or 0
   risk = risk or 0
   safety = safety or 0
   total = quality + risk + safety

Implement error handling to gracefully manage scenarios where the values are None similar to:

   try:
       total = quality + risk + safety
   except TypeError:
       total = 0  # or handle it in another way

I hope this is helpful! Do not hesitate to let me know if you have any other questions.
