Runtimewarning enable tracemalloc to get the object allocation traceback ошибка - Исправление ошибок и поиск оптимальных решений проблем

This article discusses the error ‘RuntimeWarning: Enable tracemalloc to get the object allocation traceback‘ in Python. If you are facing the same problem, check out the information below to find out the cause of this error and how to fix it by using the keyword ‘await‘.

The cause of this error

First, we need to know that ‘asyncio‘ is a library for writing concurrent code using the async/await syntax. The sleep() method of this module is used to delay the currently executing task and allow another task to be executed.

Syntax:

asyncio.sleep(delay, result=None)

The reason why we received the error is that we forgot to use the “await” keyword before the sleep() method.

To illustrate, let me reproduce the error:

import asyncio

async def main():
    print('Loading…')
    
    asyncio.sleep(3)    
    print('Welcome to our site. We are LearnShareIT!')

asyncio.run(main())

Output:

RuntimeWarning: Enable tracemalloc to get the object allocation traceback

To fix this problem, you just need to add the keyword ‘await‘ before calling the sleep() method.

The ‘await‘ keyword is used as the signal to mark the breakpoint. It allows a coroutine to temporarily suspend execution and allow the program to return to it later.

Continuing with the example above, let’s see how we fix this problem:

import asyncio

async def main():
  
    print('Loading…')
    # Add the 'await' keyword in front of the asyncio.sleep() method
    await asyncio.sleep(3)
 
    print('Welcome to our site. We are LearnShareIT!')

asyncio.run(main())

Output:

At this point the error seems to have been solved with just a small change in the code.

We set the block time to three seconds in the sleep() method. As you can see, the message ‘Loading…‘ appears first, then after ‘3‘ seconds message ‘Welcome to our site. We are LearnShareIT!‘ is printed.

Summary

To sum up, that’s all we want to talk about the error ‘RuntimeWarning: Enable tracemalloc to get the object allocation traceback‘ in Python. To solve this problem, you have to use the ‘await‘ keyword before calling the asyncio.sleep() method. Try it out in your project and see the results. Hopefully, the information we provide in this post will be helpful to you.
