search by ObjectId in mongodb with pymongo

I need to search an ObjectId with python using pymongo but I always get this error. Any ideas how to search?

import pymongo
from pymongo import MongoClient
from pymongo import ObjectId

gate = collection.find({'_id': ObjectId(modem["dis_imei"])})
print gate

Method 1

I use pymongo 2.4.1.

from bson.objectid import ObjectId
[i for i in dbm.neo_nodes.find({"_id": ObjectId(obj_id_to_find)})]
