我正在使用concurrent.futures多線程編寫我正在編寫的應用程序。Concurrent.futures - 返回導入模塊未定義的錯誤
from netaddr import IPNetwork, IPAddress
接下來,我需要一些輸入文件,我通過他們的進入我的功能被多線程:
with open(options.filename) as f:
contents = f.readlines()
executor = concurrent.futures.ProcessPoolExecutor(threads)
futures = [executor.submit(ip_compare, ip, scope_list) for ip in contents]
那我等得到
我從netaddr中輸入ip地址啓動應用程序結果完成並將它們追加到輸出變量:
for future in concurrent.futures.as_completed(futures):
output.append(future.results()
我遇到的問題是t帽子我不斷收到來自未來EXCETION:
global name 'IPAddress' is not defined
這裏是ip_compare功能:
def ip_compare(ip_addr, scope_list):
ip_addr = ip_addr.rstrip()
if not is_ipv4(ip_addr):
try:
ip = socket.gethostbyname(ip_addr)
except:
return "error," + ip_addr + ",,," + str(sys.exc_info()[0]).replace(',',';') + "\r\n"
else:
ip = ip_addr
for scope in scope_list:
if IPAddress(ip) in IPNetwork(scope):
return "in," + ip_addr + "," + ip + "," + scope + ",\r\n"
return "out," + ip_addr + "," + ip + "," + ",,\r\n"
任何想法,爲什麼期貨不能識別加載模塊?
當我的IDE停止腳本的執行,因爲錯誤的,我可以清楚地看到,ip地址是在內存中定義:
IPAddress = {type} <class 'netaddr.ip.IPAddress'>
Per [the docs](https://docs.python.org/3/library/concurrent.futures.html#processpoolexecutor),*「__main__'模塊必須可由工作程序子進程導入,這意味着ProcessPoolExecutor在交互式解釋器中不起作用。「*這意味着每個工作者子過程輸入'__main__'模塊。因此'if __name__ =='__main __''之外的全局變量被定義。 'if語句'中的那些不會被執行。 – unutbu
