Python exception: error: [Errno 10054] An existing connection was forcibly closed by the remote host

Question

我最近安装了 predictionio，用于在 vagrant box 上进行推荐。我对它很陌生。当我尝试运行其 python 示例文件 import_eventserver 时，我运行出现以下错误：

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')

正在导入数据...

Traceback (most recent call last):

关于如何知道这里出了什么问题有什么想法吗？任何帮助表示赞赏。

Answer 1

此错误与预测 IO 无关API。您收到的错误消息显示连接是从连接池中提取的，并且与服务器的连接已丢失。错误是否可重现？你没有遇到网络问题吗？请检查组件之间的网络连接。我刚刚尝试安装 w/ Python，在 Mac w/ Vagrant 上，一切对我来说都很好..

Answer 2

我认为需要以下命令来解决此错误。当您运行 PIO 事件服务器或在 VM 内部署引擎时，您需要指定“--ip 0.0.0.0”以便从主机访问事件服务器和部署的引擎：

至运行事件服务器： $ pio eventserver --ip 0.0.0.0

要部署引擎： $ pio deploy --ip 0.0.0.0
