tf.compat.v1.profiler.profile

Option Builder for Profiling API.

tf.compat.v1.profiler.ProfileOptionBuilder(
    options=None
)

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.compat.v1.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.compat.v1.profiler.ProfileOptionBuilder(
    tf.profiler.ProfileOptionBuilder.time_and_memory())
    .with_displaying_options(show_name_regexes=['.*rnn.*'])
    .build())

# Finally, profiling with the options:
_ = tf.compat.v1.profiler.profile(tf.compat.v1.get_default_graph(),
                        run_meta=run_meta,
                        cmd='scope',
                        options=opts)

Args
`options`	Optional initial option dict to start with.

Methods

`account_displayed_op_only`

View source

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.

self

`with_accounted_types`

View source

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`

View source

with_empty_output()

    outfile
)

Print the result to a file.

`with_max_depth`

View source

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`

View source

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`

View source

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`

View source

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`

Generate a pprof profile gzip file.

To use the pprof file:

Args
`pprof_file`	filename for output, usually suffixed with .pb.gz.

Returns
self.

`with_stdout_output`

View source

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

Returns
self

`with_timeline_output`

View source

with_timeline_output(
    timeline_file
)

Generate a timeline json file.
