你可以使用 await loop.run_in_executor() 在concurrent.futures 执行器中运行一个独占CPU或其它阻塞函数: python import asyncio import concurrent.futures async def main(): loop = asyncio.get_running_loop() with concurrent.futures.ThreadPoolExecutor() as pool: result = await loop.run_in_executor(pool...

把asyncio.run(main())改为asyncio.get_event_loop().run_until_complete(main())。 或者把asyncio.run(asyncio.wait(tasks))改为asyncio.get_event_loop().run_until_complete(asyncio.wait(tasks))。
