Protocol buffer representing a tensor.

Fields

dtype: i32

tensor_shape: Option<TensorShapeProto>

Shape of the tensor. TODO(touts): sort out the 0-rank issues.

version_number: i32

Version number.

In version 0, if the “repeated xxx” representations contain only one element, that element is repeated to fill the shape. This makes it easy to represent a constant Tensor with a single value.

tensor_content: Vec<u8>

Serialized raw tensor content from either Tensor::AsProtoTensorContent or memcpy in tensorflow::grpc::EncodeTensorToByteBuffer. This representation can be used for all tensor types. The purpose of this representation is to reduce serialization overhead during RPC call by avoiding serialization of many repeated small items.

half_val: Vec<i32>

DT_HALF, DT_BFLOAT16. Note that since protobuf has no int16 type, we’ll have some pointless zero padding for each value here.

float_val: Vec<f32>

DT_FLOAT.

double_val: Vec<f64>

DT_DOUBLE.

int_val: Vec<i32>

DT_INT32, DT_INT16, DT_INT8, DT_UINT8.

string_val: Vec<Vec<u8>>

DT_STRING

scomplex_val: Vec<f32>

DT_COMPLEX64. scomplex_val(2i) and scomplex_val(2i+1) are real and imaginary parts of i-th single precision complex.

int64_val: Vec<i64>

DT_INT64

bool_val: Vec<bool>

DT_BOOL

dcomplex_val: Vec<f64>

DT_COMPLEX128. dcomplex_val(2i) and dcomplex_val(2i+1) are real and imaginary parts of i-th double precision complex.

resource_handle_val: Vec<ResourceHandleProto>

DT_RESOURCE

variant_val: Vec<VariantTensorDataProto>

DT_VARIANT

uint32_val: Vec<u32>

DT_UINT32

uint64_val: Vec<u64>

DT_UINT64
