Python H20: HTTP 500 Server Error

python
h20

#1

Hi,

I was trying to use AutoML using h20 in python 3.x version. So, my code looks like:

import h2o  ## basic import
from h2o.automl import H2OAutoML
h2o.init()

htrain = h2o.H2OFrame(train) ##train and test file into h20
htest = h2o.H2OFrame(test)

x =htrain.columns
y ='visitors' ## target variable
x.remove(y)

aml = H2OAutoML(max_runtime_secs = 10)
aml.train(x=x, y =y, training_frame=htrain, leaderboard_frame = htest)

After running the last line of the code, I am receiving H20 server error as shown:

H2OServerError: HTTP 500 Server Error:
'<html>\n<head>\n<meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"/>\n<title>Error 500 Server Error</title>\n</head>\n<body>\n<h2>HTTP ERROR: 500</h2>\n<p>Problem accessing /99/AutoMLBuilder. Reason:\n<pre>    Server Error</pre></p>\n<hr /><i><small>Powered by Jetty://</small></i>\n 

Any help on this would be appreciated.

Thanks!
