Question

我有以下芹菜任务：

@task
def get_users_facebook_as_profile_icon(user_id, facebook_id):
    logger.info('Grabbing users facebook picture')
    url = "http://graph.facebook.com/%s/picture?type=large" % facebook_id

    import requests
    response = requests.get(url)
    if response.status_code != 200:
        raise Exception("Could not get facebook profile picture")
...

此后我有更多，但我一直收到以下错误：

"AssertionError('PID check failed. RNG must be re-initialized after fork(). Hint: Try Random.atfork()',)" 


Task was called with args: (3246, 17500596) kwargs: {}. 

The contents of the full traceback was:

我尝试在网上挖掘，但无法找到根本原因。但这是发生此错误的唯一任务。唯一的区别是我从Facebook下载图像，但我从未在其他地方看到过这个问题，包括我下载图像的其他任务。

如果我通过网络浏览器执行此操作，则网址效果很好，但只有通过此任务才会失败。还有什么可以促成这个吗？

我已尽力解决所有问题：（

原因如下：

始终运行以下内容：

Crypto.Random.atfork()

初始化新的工作进程时。做完了。
