Detailed Description

A RaggedTensor is a tensor with ragged dimensions, whose slice may have different lengths. We define a container for ragged tensor to support operations involving batches whose elements may have different shape.

Constructor & Destructor Documentation

RaggedTensor() [1/2]

RaggedTensor::RaggedTensor ( )

inline

RaggedTensor() [2/2]

RaggedTensor::RaggedTensor ( torch::Tensor  values, torch::Tensor  row_splits  )

inline

Constructor for creating RaggedTensor with values and row_splits.

Member Function Documentation

Add()

template<typename T >

c10::intrusive_ptr<RaggedTensor> RaggedTensor::Add ( T  value ) const

Add_()

template<typename T >

c10::intrusive_ptr<RaggedTensor> RaggedTensor::Add_ ( T  value )

inline

Clone()

c10::intrusive_ptr< RaggedTensor > RaggedTensor::Clone

(

)

const

Copy Tensor to the same device.

Concat()

c10::intrusive_ptr< RaggedTensor > RaggedTensor::Concat	(	c10::intrusive_ptr< RaggedTensor >	r_tensor,
		int64_t	axis
	)		const

Div()

inline

Div_()

template<typename T >

c10::intrusive_ptr<RaggedTensor> RaggedTensor::Div_ ( T  value )

inline

FloorDiv()

template<typename T >

c10::intrusive_ptr<RaggedTensor> RaggedTensor::FloorDiv ( T  value ) const

inline

FloorDiv_()

template<typename T >

FromRowSplits()

c10::intrusive_ptr< RaggedTensor > RaggedTensor::FromRowSplits	(	torch::Tensor	values,
		torch::Tensor	row_splits,
		bool	validate = true
	)		const

Creates a RaggedTensor with rows partitioned by row_splits.

The returned RaggedTensor corresponds with the python list defined by:

result = [values[row_splits[i]:row_splits[i + 1]]
          for i in range(len(row_splits) - 1)]

GetItem()

torch::Tensor RaggedTensor::GetItem

(

int

key

)

const

Pythonic getitem for RaggedTensor.

Returns a slice of values based on row_splits. It can be used to retrieve i'th batch element. Currently it only supports a single integer index.

GetRowSplits()

torch::Tensor RaggedTensor::GetRowSplits

(

)

const

Returns _row_splits tensor.

GetValues()

torch::Tensor RaggedTensor::GetValues

(

)

const

Returns _values tensor.

Len()

int64_t RaggedTensor::Len

(

)

const

Pythonic len for RaggedTensor.

Returns number of batch elements.

Mul()

template<typename T >

c10::intrusive_ptr<RaggedTensor> RaggedTensor::Mul ( T  value ) const

inline

Mul_()

template<typename T >

c10::intrusive_ptr<RaggedTensor> RaggedTensor::Mul_ ( T  value )

inline

ToString()

std::string RaggedTensor::ToString

(

)

const

Returns string representation.
