Landing page usage example is broken #139

Open ryanleh opened 3 years ago

Copying and running the code from the Usage section of the landing page gives the following error:

Azure Quote Provider: libdcap_quoteprov.so [ERROR]: Could not retrieve environment variable for 'AZDCAP_DEBUG_LOG_LEVEL'

Replacing the relative paths of these lines:

dtrain = xgb.DMatrix({"user1": "demo/data/train.enc"})
dtest = xgb.DMatrix({"user1": "demo/data/test.enc"})

with their appropiate absolute paths:

dtrain = xgb.DMatrix({"user1": "/home/ryan/secure-xgboost/demo/data/train.enc"})
dtest = xgb.DMatrix({"user1": "/home/ryan/secure-xgboost/demo/data/test.enc"})

fixes the issue.
