> Single fit()
> {code}

> source_table,

> model_arch_table,
> model_arch_id,
> compile_params,
> fit_params,
> num_iterations,

> {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..
