Methods

copy_meta_ranges(ranges[, mask])

Perform a copy of the underlying dataframe for the given ranges of rows.

copy_ranges(ranges)

Perform a copy of the current message, dataframe and tensors for the given ranges of rows.

copy_tensor_ranges(ranges[, mask])

Perform a copy of the underlying tensor tensors for the given ranges of rows.

from_message(message, *[, meta, ...])

Creates a new instance of a derived class from MultiMessage using an existing message as the template.

get_id_tensor()

Get the tensor that holds message ID information.

get_input(name)

Get input stored in the InferenceMemory container.

get_meta([columns])

Return column values from morpheus.pipeline.messages.MessageMeta.df.

get_meta_list([col_name])

Return a column values from morpheus.messages.MessageMeta.df as a list.

get_slice(start, stop)

Perform a slice of the current message from start:stop (excluding stop)

get_tensor(name)

Get tensor stored in the TensorMemory container.

set_meta(columns, value)

Set column values to morpheus.pipelines.messages.MessageMeta.df.

copy_meta_ranges(ranges, mask=None)[source]

Perform a copy of the underlying dataframe for the given ranges of rows.

Parameters
rangestyping.List[typing.Tuple[int, int]]

Rows to include in the copy in the form of [(`start_row, stop_row),…]` The stop_row isn’t included. For example to copy rows 1-2 & 5-7 ranges=[(1, 3), (5, 8)]

masktyping.Union[None, cupy.ndarray, numpy.ndarray]

Optionally specify rows as a cupy array (when using cudf Dataframes) or a numpy array (when using pandas Dataframes) of booleans. When not-None ranges will be ignored. This is useful as an optimization as this avoids needing to generate the mask on it’s own.

Returns
Dataframe

copy_ranges(ranges)[source]

Perform a copy of the current message, dataframe and tensors for the given ranges of rows.

Parameters
rangestyping.List[typing.Tuple[int, int]]

Rows to include in the copy in the form of [(`start_row, stop_row),…]` The stop_row isn’t included. For example to copy rows 1-2 & 5-7 ranges=[(1, 3), (5, 8)]

`MultiTensorMessage`

copy_tensor_ranges(ranges, mask=None)[source]

Perform a copy of the underlying tensor tensors for the given ranges of rows.

Parameters
rangestyping.List[typing.Tuple[int, int]]

Rows to include in the copy in the form of [(`start_row, stop_row),…]` The stop_row isn’t included. For example to copy rows 1-2 & 5-7 ranges=[(1, 3), (5, 8)]

masktyping.Union[None, cupy.ndarray, numpy.ndarray]

Optionally specify rows as a cupy array (when using cudf Dataframes) or a numpy array (when using pandas Dataframes) of booleans. When not-None ranges will be ignored. This is useful as an optimization as this avoids needing to generate the mask on it’s own.

Returns
typing.Dict[str, cupy.ndarray]

classmethod from_message(message, *, meta=None, mess_offset=- 1, mess_count=- 1, memory=None, offset=- 1, count=- 1, **kwargs)[source]

Creates a new instance of a derived class from MultiMessage using an existing message as the template. This is very useful when a new message needs to be created with a single change to an existing MessageMeta.

When creating the new message, all required arguments for the class specified by cls will be pulled from message unless otherwise specified in the args or kwargs. Special handling is performed depending on whether or not a new meta object is supplied. If one is supplied, the offset and count defaults will be 0 and meta.count respectively. Otherwise offset and count will be pulled from the input message.

Parameters
clstyping.Type[Self]

The class to create

messageMultiMessage

An existing message to use as a template. Can be a base or derived from cls as long as all arguments can be pulled from message or proveded in kwargs

metaMessageMeta, optional

A new MessageMeta to use, by default None

mess_offsetint, optional

A new mess_offset to use, by default -1

mess_countint, optional

A new mess_count to use, by default -1

memoryTensorMemory, optional

A new TensorMemory to use. If supplied, offset and count default to 0 and memory.count respectively. By default None

offsetint, optional

A new offset to use, by default -1

countint, optional

A new count to use, by default -1

Returns
Self

A new instance of type cls

Raises
ValueError

If the incoming message is None

get_id_tensor()[source]

Get the tensor that holds message ID information. Equivalent to get_tensor(id_tensor_name)

Returns
cupy.ndarray

Array containing the ID information

Raises
KeyError

If self.id_tensor_name is not found in the tensors

get_input(name)[source]

Get input stored in the InferenceMemory container. Alias for MultiInferenceMessage.get_tensor.

Parameters
namestr

Input key name.

Returns
cupy.ndarray

Inference input.

Raises
KeyError

When no matching input tensor exists.

get_meta(columns=None)[source]

Return column values from morpheus.pipeline.messages.MessageMeta.df.

Parameters
columnstyping.Union[None, str, typing.List[str]]

Input column names. Returns all columns if None is specified. When a string is passed, a Series is returned. Otherwise a Dataframe is returned.

Returns
Series or Dataframe

Column values from the dataframe.

get_meta_list(col_name=None)[source]

Return a column values from morpheus.messages.MessageMeta.df as a list.

Parameters
col_namestr

Column name in the dataframe.

Returns
List[str]

Column values from the dataframe.

get_slice(start, stop)[source]

Perform a slice of the current message from start:stop (excluding stop)

For example to slice from rows 1-3 use m.get_slice(1, 4). The returned MultiTensorMessage will contain references to the same underlying Dataframe and tensor tensors, and this calling this method is reletively low cost compared to MultiTensorMessage.copy_ranges

Parameters
startint

Starting row of the slice

stopint

Stop of the slice
