h2o.saveModel在Windows 8上拋出目錄異常

我在R中使用h2o 3.0.0.22版本，我試圖保存我的模型。但我似乎無法弄清楚預期的格式。我嘗試了各種各樣的變化，但得到各種不同的例外。h2o.saveModel在Windows 8上拋出目錄異常

h2o.saveModel(model, dir="c:/temp", name= "my.model")

我如何保存我的模式我的Windows 8機器上？

UPDATE：此命令在這裏似乎創建一個文件夾&文件：

h2o.saveModel(model, filename="file:///C:/temp/model")

這創造了一個文件：C:/temp/DeepLearningModel__8412f3ab21699b5593aa5c6861c8468d.bin 但隨後拋出一個不同的錯誤：

ERROR: Unexpected HTTP Status code: 400 Bad Request (url = http://127.0.0.1:54321/3/Models.bin/DeepLearningModel__8412f3abf1699b5593a55c6861c8468d?dir=file%3A%2F%2F%2FC%3A%2Ftemp%2Fmodel&force=0)

謝謝。使用這個語法'h2o.saveModel（model，filename =「file：/// C：/ temp/model」）' – Sam7
