mxnet.monitor.Monitor¶

class mxnet.monitor.Monitor(interval, stat_func=None, pattern='.*', sort=False)[source]¶

Monitor outputs, weights, and gradients for debugging.

Parameters

interval (int) – Number of batches between printing.
stat_func (function) – A function that computes statistics of tensors. Takes an NDArray and returns an 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 and ‘.*backward.*’ will print all gradients.

__init__(interval, stat_func=None, pattern='.*', sort=False)[source]¶: Initialize self. See help(type(self)) for accurate signature.

Methods

`__init__`(interval[, stat_func, pattern, sort])	Initialize self.
`install`(exe)	install callback to executor.
`tic`()	Start collecting stats for current batch.
`toc`()	End collecting for current batch and return results.
`toc_print`()	End collecting and print results.
