In Exercise 1 of the Module 5 assignment, I added a simplified prompt in the graded code area and executed the code, the unit testcase run and the subsequent test fails with `UnboundLocalError: cannot access local variable ‘response’ where it is not associated with a value`. I have noticed that this happens primarily for simplified=True function calls. I tried to manually execute the function `check_if_faq_or_product` , the no response issue pops up only when simplified is set to True. Call: `check_if_faq_or_product(‘How can I contact the user support?’, False)` Result: `(‘FAQ’, 220)` Call: `check_if_faq_or_product(‘How can I contact the user support?’, True)` Result: ```auto UnboundLocalError Traceback (most recent call last) Cell In[33], line 99 96 label = ‘undefined’ 98 return label, total_tokens —> 99 check_if_faq_or_product(‘How can I contact the user support?’, True) Cell In[33], line 85, in check_if_faq_or_product(query, simplified) 81 router_span.set_status(Status(StatusCode.OK)) 84 # Get the Label by accessing the content key of the response dictionary —> 85 label = response[‘choices’][0][‘message’][‘content’] 86 total_tokens = response[‘usage’][‘total_tokens’] 87 span.set_output(str({“label”: label, ‘total_tokens’:total_tokens})) UnboundLocalError: cannot access local variable ‘response’ where it is not associated with a value ``` I wonder if the tracer is broken somehow. Specifically this code’s execution: ```auto with tracer.start_as_current_span("routing_faq_or_product", openinference_span_kind = 'tool') as span: span.set_input(str({"query":query, "simplified": simplified})) ``` I tried to skip the 1.4 Optional Telemetry setup to prevent the tracer issues, but realized that’s not possible as tracer is a necessary variable to run 4.1 exercise. So is 1.4 mandatory and not optional, unlike the title says? Please find the Lab ID and the error messages below. > LAB ID: qrbdmogghssj Response of Unit Test cases: ```auto Failed test case: check_if_faq_or_product raised an exception with the following parameters query = What are your working hours?. Expected: check_if_faq_or_product must run without exceptions Got: cannot access local variable 'response' where it is not associated with a value ``` Running the following unedited test `Let’s test both versions` code: ```auto queries = [ ‘What is your return policy?’, ‘Give me three examples of blue T-shirts you have available.’, ‘How can I contact the user support?’, ‘Do you have blue Dresses?’, ‘Create a look suitable for a wedding party happening during dawn.’ ] labels = [‘FAQ’, ‘Product’, ‘FAQ’, ‘Product’, ‘Product’] for query, correct_label in zip(queries, labels): # Call check_if_faq_or_product and store the results response_std, tokens_std = check_if_faq_or_product(query, simplified=False) response_simp, tokens_simp = check_if_faq_or_product(query, simplified=True) # Print results process_and_print_query(query, correct_label, response_std, tokens_std, response_simp, tokens_simp) ``` Result: ```auto UnboundLocalError Traceback (most recent call last) Cell In[20], line 14 11 for query, correct_label in zip(queries, labels): 12 # Call check_if_faq_or_product and store the results 13 response_std, tokens_std = check_if_faq_or_product(query, simplified=False) ---> 14 response_simp, tokens_simp = check_if_faq_or_product(query, simplified=True) 16 # Print results 17 process_and_print_query(query, correct_label, response_std, tokens_std, response_simp, tokens_simp) Cell In[18], line 85, in check_if_faq_or_product(query, simplified) 81 router_span.set_status(Status(StatusCode.OK)) 84 # Get the Label by accessing the content key of the response dictionary ---> 85 label = response['choices'][0]['message']['content'] 86 total_tokens = response['usage']['total_tokens'] 87 span.set_output(str({"label": label, 'total_tokens':total_tokens})) UnboundLocalError: cannot access local variable 'response' where it is not associated with a value ``` ---

hi @sriharishj is this the first exercise test result? can you DM me screenshot of your codes by personal DM. Also just to be sure, I hope you know there were changed made to labs multiple times due to multiple issue arising from deprecated model. So before you started, did you make sure to get updated notebook by rebooting and clicking Get the latest version?? Also in the section where you provided queries and then labels. Don’t mention labels in separate line, rather mention for each query you wrote, next to it mention if it is FAQ or product label, something like this Do you have blue dress? Label: Product Regards Dr. Deepti ---

Hi @Deepti_Prasad, Thank you for your quick response. Yes, this is the First exercise’s test result. I did delete all the files (to make sure they got updated), rebooted and got the latest version before submitting my query here. I did redo it a couple times with clearing my browser cache to verify and the issue still persists. I’ll send over the screenshots via DM now. Those queries and labels mentioned are not my code, but rather an un-editable code section present after the 1st exercise’s unit test function call. I have mentioned the examples in my prompt as per your recommendation. Thank you for pointing it out anyways. Regards, Sri Harish ---

Hi! Thanks for tagging me @Deepti_Prasad! This issue happened due to a deprecated model, which has been fixed. You can close and open the assignment to fetch the fixed version. Cheers, Lucas ---

@sriharishj your latest error looks more to check with your codes than general lab issues which currently rag labs is experiencing. please check your codes again. this looks like your prompts need more option to choose between to get response as you mentioned only single examples with each label category. ---

You are right, thank you. Adding additional examples and restarting the Kernel, fixed the response error. Thank you again. ---

great 👏👏 for label category related prompt, i always provide minimum of 3 prompt examples for each label categories. Remember "“the more refined your prompt is, resulting in better response with the context window choice for llm response. leaving this thread open, in case you get any further error related to this selected lab, post the error screenshot error without posting any codes here.(based on community guidelines) Good luck! Keep Learning! Regards Dr. Deepti ---

I am getting this exact same error. What is going on? I have restarted the kernel. At one point it the model was giving me wrong classifications. May be that is tuning of the prompt. But this error here is very frustrating: * * * UnboundLocalError Traceback (most recent call last) Cell In[19], line 1 ----\> 1 unittests.test\_check\_if\_faq\_or\_product(check\_if\_faq\_or\_product) File ~/work/unittests.py:98, in test\_check\_if\_faq\_or\_product(learner\_func) 87 cases.append(t) 90 return cases —\> 98 cases = g() 99 print\_feedback(cases) File ~/work/unittests.py:72, in test\_check\_if\_faq\_or\_product..g() 70 for query, correct\_label in zip(queries, labels): 71 t = test\_case() —\> 72 response, total\_tokens = learner\_func(query, simplified = True) 73 label = response 74 if label != correct\_label: Cell In[18], line 81, in check\_if\_faq\_or\_product(query, simplified) 77 router\_span.set\_status(Status(StatusCode.OK)) 80 # Get the Label by accessing the content key of the response dictionary —\> 81 label = response[‘choices’][0][‘message’][‘content’] 82 total\_tokens = response[‘usage’][‘total\_tokens’] 83 span.set\_output(str({“label”: label, ‘total\_tokens’:total\_tokens})) UnboundLocalError: cannot access local variable ‘response’ where it is not associated with a value Also, is 1.4 optional or not? ---

hello @dpritham Looks like you are old user and yet you have posted on an older thread. kindly always post a new topic with your failed unittest screenshot. you can always sharing Link of the similar post matching to your problem. even though error might be similar, the cause of the same error will vary from different code implementation. Your error surely points for a code review, so please click on my name and then message me code screenshots for your failed unittest. Regards Dr. Deepti
