Troubleshooting Errors with Azure OpenAI and NVIDIA’s Nemo Guardrails

Recently, I encountered a significant issue while using the latest version of NVIDIA’s Nemo Guardrails in conjunction with Azure OpenAI. Up until now, I had configured and utilized Nemo Guardrails version 0.11.0 without any hitches. However, after upgrading to version 0.14.0, I started receiving an unexpected error that halted my progress.

To investigate, I meticulously delved into the configuration settings to verify that all model settings were appropriately defined in the configuration folder. To my relief, everything appeared to be correct. Despite this, the new version of Nemo seemed to have introduced changes that were not clearly documented, particularly regarding the model configuration.

The error message I received was particularly cryptic:

ModelInitializationError: Failed to initialize model 'gpt-40-mini' with provider 'azure' in 'chat' mode: ValueError encountered in initializer_init_text_completion_model(modes=['text', 'chat']) ...

Among the issues highlighted was a validation error indicating that it could not locate the required OPENAI_API_KEY. This has been specified many times for proper functioning, but I had ensured that the environment variable was set up adequately. The message suggested two solutions: either include the OPENAI_API_KEY in your environment variables or pass it as a named parameter during initialization.

To anyone facing similar challenges, I recommend revisiting their environmental setups and checking the latest documentation for Nemo Guardrails. Since I could not find explicit updates or changes about the configuration in the current release notes, it’s crucial to explore community insights or official forums for possible solutions or workarounds.
