Question

我最近安装了预测有关流浪盒的建议。我对它很新。当我尝试运行其python示例文件import_eventserver时，我遇到以下错误：

C:\HashiCorp\Vagrant\PredictionIO-Vagrant-0.8.2\MyRecommendation>python data/imp
ort_eventserver.py --access_key some_access_key
Namespace(access_key='some_access_key', file='./data/sample_movielens_data.txt', url='http://localhost:7070')

导入数据......

Traceback (most recent call last):
  File "data/import_eventserver.py", line 76, in <module>
    import_events(client, args.file)
  File "data/import_eventserver.py", line 45, in import_events

关于如何知道这里错误的任何想法？任何帮助表示赞赏。

Answer 1

此错误与Prediction IO API无关。您收到的错误消息显示从连接池中提取连接，并且与服务器的连接已丢失。错误是否可重现？你有没有网络问题？请检查组件之间的网络连接。我刚尝试并在Mac上安装了带有Python的Vagrant，一切都运行良好..

Answer 2

我认为需要以下命令才能解决此错误。当您在VM中运行PIO事件服务器或部署引擎时，您需要指定“--ip 0.0.0.0”以便从主机访问事件服务器和已部署的引擎：

运行eventserver： $ pio eventserver --ip 0.0.0.0

部署引擎： $ pio deploy --ip 0.0.0.0

Python异常：错误：[Errno 10054]远程主机强制关闭现有连接
