它在local上运行得很好，但不能在mapreduce上运行。是因为我在reducer.py中使用了一些第三方库吗？
在gcp控制台shell中，我使用以下命令启动mapreduce：

gcloud dataproc jobs submit hadoop --cluster cc-1 --region=us-central1 --jar file:///usr/lib/hadoop-mapreduce/hadoop-streaming.jar --files=mapper.py,reducer.py -- -mapper "mapper.py" -reducer "reducer.py" -input gs://2018weather/2018.csv -output gs://2018weather/output-streaming

错误信息如下：
