我想用Kafka MultiProcessConsumer 但我有以下错误。这个错误似乎与python中的多线程有关
这是我正在使用的代码。 simple.py ```
from kafka import SimpleProducer, SimpleClient, SimpleConsumer, MultiProcessConsumer

To consume messages

client = SimpleClient('localhost:9092')
consumer = MultiProcessConsumer(client, "my-group", "testing_topic", num_procs=3)
for message in consumer:
# message is raw byte string -- decode if necessary!
# e.g., for unicode: message.decode('utf-8')
print(message)

client.close()

运行上述代码时出错。

$ python simple.py
