-----------------------------------
Summary: DL: Fit and evaluate changes for asymmetric cluster config
Key: MADLIB-1393
URL: https://issues.apache.org/jira/browse/MADLIB-1393
Project: Apache MADlib
Issue Type: New Feature
Components: Deep Learning
Reporter: Ekta Khanna
Fix For: v1.17
Single fit()

)
{code}
{{use_gpus}} (optional)
BOOLEAN, *default*: FALSE (i.e., CPU). Determines whether GPUs are to be used
for training the neural network. Set to TRUE to use GPUs.
*Note*
This parameter must not conflict with how the distribution rules are set in the
preprocessor function. For example, if you set a distribution rule to use
certain segments on hosts that do not have GPUs attached, you will get an error
if you set {{use_gpus}} to TRUE.
Also, we have seen some memory related issues when segments share GPU
resources. For example, if you have 4 segments sharing 1 GPU, you may get
memory related errors. The recommended configuration is to have 1 GPU per
segment.
Multi model fit()
Same idea as above ^^^ for single model fit.
Evaluate
Same idea as above ^^^ for single model fit..
