Profile Results¶

✨ New in Katana 6

Module that contains functions and definitions for handling profile results.

class Performance.ProfileResults.MixedValueType(*args, **kwargs)¶

Bases: object

Singleton class that represents an unspecified value that is the result of a number of mixed values.

static __new__(cls, *args, **kwargs)¶: Create and return a new object. See help(type) for accurate signature.

class Performance.ProfileResults.ProfileResults¶

Bases: object

A container of the results of a profiling session.

These files are the JSON documents generated as a result of a B{Preview Render with Profiling}.

Since: Katana 6.0v1

CATEGORICAL_FIELDS = (<Field.OP_ID: 'opId'>, <Field.OP_NAME: 'opName'>, <Field.OP_TYPE: 'opType'>, <Field.NODE_NAME: 'nodeName'>, <Field.NODE_TYPE: 'nodeType'>)¶

class Field(value)¶

Bases: enum.Enum

Available fields in every record.

OP_ID = 'opId'¶

OP_NAME = 'opName'¶

OP_TYPE = 'opType'¶

NODE_NAME = 'nodeName'¶

NODE_TYPE = 'nodeType'¶

CPU_TIME = 'cpuTime'¶

QUANTITATIVE_FIELDS = (<Field.CPU_TIME: 'cpuTime'>,)¶

class Record(data: dict)¶

Bases: object

A profile results record or aggregate record.

__init__(data: dict)¶

Initializes an instance of the class.

Parameters: data (dict) – The underlying dictionary that contains the data.

property cpuTime: Optional[float]¶

Return type: float, or None
Returns: The CPU time in the record.

get(key, default=None) → Any¶

property nodeName: Optional[Union[str, Performance.ProfileResults.MixedValueType]]¶

Return type: str, MixedValue, or None
Returns: The node name in the record.

property nodeType: Optional[Union[str, Performance.ProfileResults.MixedValueType]]¶

Return type: str, MixedValue, or None
Returns: The node type in the record.

property opId: Optional[Union[int, Performance.ProfileResults.MixedValueType]]¶

Return type: int, MixedValue, or None
Returns: The Op ID in the record.

property opName: Optional[Union[str, Performance.ProfileResults.MixedValueType]]¶

Return type: str, MixedValue, or None
Returns: The Op name in the record.

property opType: Optional[Union[str, Performance.ProfileResults.MixedValueType]]¶

Return type: str, MixedValue, or None
Returns: The Op type in the record.

__init__()¶: Initializes an instance of the class.

property cpuTime: Optional[float]¶

Return type: float or None
Returns: The accumulated CPU time (in seconds) of each of the cooked locations, as defined in the profile results file. If not available, None is returned. This value is equivalent to the sum of the cook time of every cooked location.

classmethod fromFile(filepath: str) → Performance.ProfileResults.ProfileResults ¶

Loads the profile results file.

Return type: ProfileResults
Parameters: filepath (str) – Path to the profile results file.
Returns: The newly created instance with the data loaded.

classmethod fromString(content: str) → Performance.ProfileResults.ProfileResults ¶

Parses the provided data and creates an instance of the ProfileResults class.

Return type: ProfileResults
Parameters: content (str) – Content of the profile results file.
Returns: The newly created instance with the data loaded.

getRecords(groupBy: Optional[Performance.ProfileResults.ProfileResults.Field] = None, sortBy: Optional[Performance.ProfileResults.ProfileResults.Field] = None) → tuple¶

Gets the rows from the results object, optionally grouped and/or sorted by a field.

Return type

tuple of ProfileResults.Record

Parameters

groupBy (ProfileResults.Field, or None) – The field to group the records by.
sortBy (ProfileResults.Field, or None) – The field to sort the records by.

Returns

A tuple containing the records.

Raises

ValueError – If the field provided in groupBy is not a categorical field. See ProfileResults.CATEGORICAL_FIELDS.

property opCount: Optional[int]¶

Return type: int or None
Returns: The number of Ops in the Op Tree in the profiling session. If the value is not defined in the profile results file, None is returned. This value generally matches the number of records in the file when grouped by Op ID or Op name, provided that no Op has not been collapsed as part of the Op Tree optimizations.

property wallTime: Optional[float]¶

Return type: float or None
Returns: The total time (in seconds) between the profiling session start and the profiling session end. If the value is not defined in the profile results file, None is returned.
