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 B{Preview Render with Profiling}.

Since:

Katana 6.0v1

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

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 cpuTime: float | None
Return type:

float, or None

Returns:

The CPU time in the record.

__init__()

Initializes an instance of the class.

classmethod fromFile(filepath: str) → 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) → 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.

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.

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.

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.

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

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

Return type:

tuple of ProfileResults.Record

Parameters:
Returns:

A tuple containing the records.

Raises:

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