Python h2o в windows: невозможно инициализировать (TypeError: аргумент типа «NoneType» не итерируется)

Question

Я пытаюсь использовать python h2o в своей компании.

После использования команды:

>import h2o 
> h2o.init() 

Я получил

h2o\connection.py:110: UserWarning: Proxy environment variable `HTTP_PROXY` with value `http://username:password@proxy.**.com:8080` found. This may interfere with your H2O Connection. 
warnings.warn("Proxy environment variable `" + name + "` with value `" + value + "` found. This may interfere with your H2O Connection.") 

h2o\connection.py:110: UserWarning: Proxy environment variable `HTTPS_PROXY` with value `https://username:password@proxy.**.com:8080` found. This may interfere with your H2O Connection. 
warnings.warn("Proxy environment variable `" + name + "` with value `" + value + "` found. This may interfere with your H2O Connection.")

    needquote = (" " in arg) or ("\t" in arg) or not arg 

TypeError: argument of type 'NoneType' is not iterable 

Я попытался установить значение переменной по имени прокси в Init(), он все же дал мне такую ​​же ошибку ,

После попытки

h2o.init(start_h2o=False) 

Я получил

h2o\connection.py:110: UserWarning: Proxy environment variable `HTTP_PROXY` with value `http://username:password@proxy.**.com:8080` found. This may interfere with your H2O Connection. 
    warnings.warn("Proxy environment variable `" + name + "` with value `" + value + "` found. This may interfere with your H2O Connection.")

    if not start_h2o: raise ValueError("Cannot connect to H2O server. Please check that H2O is running at {}".format(H2OConnection.make_url(""))) 
ValueError: Cannot connect to H2O server. Please check that H2O is running at http://localhost:54321/3/ 

Кстати, версия h2o я использовал 3.8.2.5. Спасибо заранее.

Answer 1

Отключение прокси должно устранить проблему.
