The community member is encountering a RuntimeError when using asyncio.run() in Colab. Another community member suggests running import nest_asyncio and nest_asyncio.apply() at the top to resolve the issue. The second comment simply expresses gratitude.
In Colab I'm getting RuntimeError: asyncio.run() cannot be called from a running event loop for response_str = response.response for source_node in response.source_nodes: eval_result = evaluator.evaluate(response=response_str, contexts=[source_node.get_content()]) print(str(eval_result.passing))
