tf.profiler.ProfileOptionBuilder

Class ProfileOptionBuilder

Defined in tensorflow/python/profiler/option_builder.py.

Option Builder for Profiling API.

For tutorial on the options, see https://github.com/tensorflow/tensorflow/tree/master/tensorflow/core/profiler/g3doc/options.md

# Users can use pre-built options:
opts = (
    tf.profiler.ProfileOptionBuilder.trainable_variables_parameter())

# Or, build your own options:
opts = (tf.profiler.ProfileOptionBuilder()
    .with_max_depth(10)
    .with_min_micros(1000)
    .select(['accelerator_micros'])
    .with_stdout_output()
    .build()

# Or customize the pre-built options:
opts = (tf.profiler.ProfileOptionBuilder(
    tf.profiler.ProfileOptionBuilder.time_and_memory())
    .with_displaying_options(show_name_regexes=['.*rnn.*'])
    .build())

# Finally, profiling with the options:
_ = tf.profiler.profile(tf.get_default_graph(),
                        run_meta=run_meta,
                        cmd='scope',
                        options=opts)

Methods

__init__

__init__(options=None)

Constructor.

Args:

• options: Optional initial option dict to start with.

account_displayed_op_only

account_displayed_op_only(is_true)

Whether only account the statistics of displayed profiler nodes.

Args:

• is_true: If true, only account statistics of nodes eventually displayed by the outputs. Otherwise, a node's statistics are accounted by its parents as long as it's types match 'account_type_regexes', even if it is hidden from the output, say, by hide_name_regexes.

Returns:

self

build

build()

Build a profiling option.

Returns:

A dict of profiling options.

float_operation

@staticmethod
float_operation()

Options used to profile float operations.

Please see https://github.com/tensorflow/tensorflow/tree/master/tensorflow/core/profiler/g3doc/profile_model_architecture.md on the caveats of calculating float operations.

Returns:

A dict of profiling options.

order_by

order_by(attribute)

• min_output_bytes: Only show profiler nodes have no less than this bytes output. The output are not necessarily allocated by this profiler nodes.

Returns:

A dict of profiling options.

trainable_variables_parameter

@staticmethod
trainable_variables_parameter()

Options used to profile trainable variable parameters.

Normally used together with 'scope' view.

Returns:

A dict of profiling options.

with_accounted_types

with_accounted_types(account_type_regexes)

Selectively counting statistics based on node types.

Here, 'types' means the profiler nodes' properties. Profiler by default consider device name (e.g. /job:xx/.../device:GPU:0) and operation type (e.g. MatMul) as profiler nodes' properties. User can also associate customized 'types' to profiler nodes through OpLogProto proto.

For example, user can select profiler nodes placed on gpu:0 with: account_type_regexes=['.*gpu:0.*']

If none of a node's properties match the specified regexes, the node is not displayed nor accounted.

Args:

• account_type_regexes: A list of regexes specifying the types.

Returns:

self.

with_empty_output

with_empty_output()

Do not generate side-effect outputs.

with_file_output

with_file_output(outfile)

Print the result to a file.

with_max_depth

with_max_depth(max_depth)

Set the maximum depth of display.

The depth depends on profiling view. For 'scope' view, it's the depth of name scope hierarchy (tree), for 'op' view, it's the number of operation types (list), etc.

Args:

• max_depth: Maximum depth of the data structure to display.

Returns:

self

with_min_execution_time

with_min_execution_time(
    min_micros=0,

Returns:

self

with_min_float_operations

with_min_float_operations(min_float_ops)

Only show profiler nodes consuming no less than 'min_float_ops'.

Please see https://github.com/tensorflow/tensorflow/tree/master/tensorflow/core/profiler/g3doc/profile_model_architecture.md on the caveats of calculating float operations.

Args:

with_min_memory(
    min_bytes=0,
    min_peak_bytes=0,
    min_residual_bytes=0,
    min_output_bytes=0
)

Only show profiler nodes consuming no less than 'min_bytes'.

Args:

• min_bytes: Only show profiler nodes requested to allocate no less bytes than this.
• min_peak_bytes: Only show profiler nodes using no less than this bytes at peak (high watermark). For profiler nodes consist of multiple graph nodes, it sums the graph nodes' peak_bytes.
• min_residual_bytes: Only show profiler nodes have no less than this bytes not being de-allocated after Compute() ends. For profiler nodes consist of multiple graph nodes, it sums the graph nodes' residual_bytes.
• min_output_bytes: Only show profiler nodes have no less than this bytes output. The output are not necessarily allocated by this profiler nodes.

Returns:

self

with_min_occurrence

with_min_occurrence(min_occurrence)

Only show profiler nodes including no less than 'min_occurrence' graph nodes.

A "node" means a profiler output node, which can be a python line (code view), an operation type (op view), or a graph node (graph/scope view). A python line includes all graph nodes created by that line, while an operation type includes all graph nodes of that type.

Args:

• min_occurrence: Only show nodes including no less than this.

Returns:

self

with_min_parameters

with_min_parameters(min_params)

Only show profiler nodes holding no less than 'min_params' parameters.

'Parameters' normally refers the weights of in TensorFlow variables. It reflects the 'capacity' of models.

Args:

• min_params: Only show profiler nodes holding number parameters no less than this.

Returns:

self

with_node_names

with_node_names(
    start_name_regexes=None,
    show_name_regexes=None,
    hide_name_regexes=None,
    trim_name_regexes=None
)

Regular expressions used to select profiler nodes to display.

After 'with_accounted_types' is evaluated, 'with_node_names' are evaluated as follows:

For a profile data structure, profiler first finds the profiler nodes matching 'start_name_regexes', and starts displaying profiler nodes from there. Then, if a node matches 'show_name_regexes' and doesn't match 'hide_name_regexes', it's displayed. If a node matches 'trim_name_regexes', profiler stops further searching that branch.

Args:

• start_name_regexes: list of node name regexes to start displaying.
• show_name_regexes: list of node names regexes to display.
• hide_name_regexes: list of node_names regexes that should be hidden.
• trim_name_regexes: list of node name regexes from where to stop.

Returns:

self

with_pprof_output

with_pprof_output(pprof_file)

Generate a pprof profile gzip file.

To use the pprof file: pprof -png --nodecount=100 --sample_index=1

Args:

• pprof_file: filename for output, usually suffixed with .pb.gz.

Returns:

self.

with_stdout_output

with_stdout_output()

Print the result to stdout.

with_step

with_step(step)

Which profile step to use for profiling.

The 'step' here refers to the step defined by Profiler.add_step() API.

Args:

• step: When multiple steps of profiles are available, select which step's profile to use. If -1, use average of all available steps.

Returns:

self

with_timeline_output

with_timeline_output(timeline_file)

Generate a timeline json file.
