windows中的Python h2o:无法初始化（TypeError:类型为'；非类型为'；的参数不可初始化）

我正在我的公司尝试使用python h2o

使用命令后：

>import h2o
> h2o.init()

我得到

我得到

h2o\connection.py:110:UserWarning:Proxy环境变量'HTTP\u Proxy'，具有值`http://username:password@找到代理。**.com:8080`。这可能会干扰您的H2O连接。

ValueError:无法连接到H2O服务器。请检查H2O是否正在运行http://localhost:54321/3/

顺便说一下，我使用的h2o版本是3.8.2.5。

提前感谢。

关闭代理应该可以解决问题。

1）使用命令“python filename.py proxy=（default）”运行对我来说很有效，因为这使h2o连接使用默认环境代理

2） 已删除“我的环境变量”中存在的用户变量中的http_代理

希望这有帮助

您应该检查防火墙是否允许与h2o服务器连接。也许可以先禁用防火墙试试

关闭代理是什么意思？你的意思是取消选中IE中代理服务器的复选框吗？如果是这种情况，错误仍然存在。“我试图在init（）中设置名为proxy的变量的值，…”。你能准确地显示你键入的内容吗？我尝试了

h2o.init（proxy={'http'：'http://myusername:mypassword@代理地址：端口'，'https'：'https://myusername:mypassword@代理服务器（地址：端口“}）

。它给了我同样的错误。
