retrying.RetryError: RetryError[尝试: 1289627，值:无]

Question

我试图按下面的方式使用重试模块，但是遇到了retrying.RetryError:每当遇到stop_max_delay时，如果有人提供如何修复它的输入，我会很感激。

import time
from retrying import retry    
def retry_if_result_none(result):
    """Return True if we should retry (in this case when result is None), False otherwise"""
    return result is None

@retry(stop_max_delay=10000,retry_on_result=retry_if_result_none)
def might_return_none():
    print "Retry forever ignoring Exceptions with no wait if return value is True"

print "Start : %s" % time.ctime()
might_return_none()
print "End : %s" % time.ctime()

错误：-

  File "check_devices.py", line 15, in <module>
    might_return_none()
  File "build\bdist.win-amd64\egg\retrying.py", line 49, in wrapped_f
  File "build\bdist.win-amd64\egg\retrying.py", line 214, in call
retrying.RetryError: RetryError[Attempts: 1289627, Value: None]

你应该像下面这样做

from retrying import retry, RetryError

try:
    might_return_none()
except RetryError as e:
    print "RetryError"
    print "End : %s" % time.ctime()
