用下面的代碼使得:'集合' 的對象不是在pymongo可調用錯誤與處理池
'Collection' object is not callable. If you meant to call the '__getnewargs__' method on a 'Collection' object it is failing because no such method exists.
的代碼: 從多處理進口普爾 分貝= MongoClient(IP,端口)
def f(cursor, arg):
for doc in cursor:
...
p = Pool(4)
for arg in args:
cursor = db[dbName][collName].find()
p.apply_async(f,[cursor, arg])
db.close()
找不出什麼問題以及如何調試代碼。
完全回溯:

在克隆光標線程之前顯式拉文件錯誤發生在哪一行? –

是從最高級'multiprocessing'軟件包,還是從其他模塊(如'multiprocessing.dummy'或pymongo中的某個模塊)導入'Pool'? – Blckknght
