NAME

            

              
              
AI::MXNet::Monitor - Monitor outputs, weights, and gradients for debugging.
            
          

DESCRIPTION

            

              
              
Monitor outputs, weights, and gradients for debugging.
Parameters
----------
interval : Int
    Number of batches between printing.
stat_func : CodeRef
    a function that computes statistics of tensors.
    Takes a NDArray and returns a NDArray. defaults to mean
    absolute value |x|/size(x).
pattern : Str
    A regular expression specifying which tensors to monitor.
    Only tensors with names that match name_pattern will be included.
    For example, '.*weight|.*output' will print all weights and outputs;
    '.*backward.*' will print all gradients.
            
          

install

            

              
              
install callback to executor.
Supports installing to multiple exes.
Parameters
----------
$exe : AI::MXNet::Executor
    the Executor (returned by $symbol->bind) to install to.
