H2O python split_frame抛出异常

Question

我正试图分割我的h2o帧，我一直得到下面的异常，但我能够看到流UI中的分割帧。我试图查找文档，试图找到如何加载我在Flow UI中看到的框架到我的python shell，但也没有运气。

data = h2o.import_frame("train.csv")
Parse Progress: [##################################################] 100%
Imported train.csv. Parsed 878,035 rows and 5 cols
splits = data.split_frame(ratios=[0.80])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/h2o/frame.py", line 598, in split_frame
    return [h2o.get_frame(i["name"]) for i in j["destination_frames"]]
  File "/usr/local/lib/python2.7/dist-packages/h2o/h2o.py", line 183, in get_frame
    return H2OFrame.get_frame(frame_id)
  File "/usr/local/lib/python2.7/dist-packages/h2o/frame.py", line 50, in get_frame
    res = h2o.H2OConnection.get_json("Frames/"+urllib.quote(frame_id))["frames"][0]

    raw_txt = self._do_raw_rest(url_suffix, method, file_upload_info, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/h2o/connection.py", line 466, in _do_raw_rest
    .format(http_result.status_code,http_result.reason,method,url,detailed_error_msgs))
EnvironmentError: h2o-py got an unexpected HTTP status code:

Answer 1

在最新的稳定版本

中修复了这个问题http://h2o-release.s3.amazonaws.com/h2o/rel-simons/7/index.html

python在进入下一步之前没有轮询等待分割帧完成(导致未发现异常)
