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)

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 Preview Render with Profiling.

Since:: Katana 6.0v1

CATEGORICAL_FIELDS = (Field.OP_ID, Field.OP_NAME, Field.OP_TYPE, Field.NODE_NAME, Field.NODE_TYPE)

class Field(value)

Bases: 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,)

class Record(data: dict)

Bases: object

A profile results record or aggregate record.

Parameters:: data (dict)

__init__(data: dict)

Initializes an instance of the class.

Parameters:

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

property cpuTime: float | None

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

get(key, default=None) → Any

Return type:: Any

property nodeName: str | MixedValueType | None

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

property nodeType: str | MixedValueType | None

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

property opId: int | MixedValueType | None

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

property opName: str | MixedValueType | None

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

property opType: str | MixedValueType | None

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

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

property cpuTime: float | None

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) → ProfileResults

Loads the profile results file.

Return type:

ProfileResults

Parameters:

filepath (str) – Path to the profile results file.
filepath

Returns:

The newly created instance with the data loaded.

Return type:

ProfileResults

classmethod fromString(content: str) → 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.
content

Returns:

The newly created instance with the data loaded.

Return type:

ProfileResults

getRecords(groupBy: Field | None = None, sortBy: Field | None = None) → tuple[Record]

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

Return type:

tuple of ProfileResults.Record

Parameters:

groupBy (Field | None, default: None) – The field to group the records by.
sortBy (Field | None, default: None) – The field to sort the records by.
groupBy
sortBy

Returns:

A tuple containing the records.

Raises:

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

Return type:

tuple[Record]

property opCount: int | None

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: float | None

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.
