# `class tensorflow::TensorShape`
Represents the shape of a Tensor .
A tensor's shape is denoted by its number of dimensions and a size for each dimension. For example, a Tensor represented by a 3 x 4 matrix would have a shape of 2-D, [3,4].
If you know the exact shape of your Tensor when you create the TensorShape object, you can specify it then, or you can create a TensorShape with zero dimensions and one element, and call AddDim() to add dimensions later.
###Member Details
#### `uint8 tensorflow::TensorShape::buf[16][16]` {#uint8_tensorflow_TensorShape_buf_16_}
#### `Rep64* tensorflow::TensorShape::unused_aligner` {#Rep64_tensorflow_TensorShape_unused_aligner}
#### `tensorflow::TensorShape::TensorShape(gtl::ArraySlice< int64 > dim_sizes)` {#tensorflow_TensorShape_TensorShape}
Construct a ` TensorShape ` from the provided sizes. REQUIRES: `dim_sizes[i] >= 0`
#### `tensorflow::TensorShape::TensorShape(std::initializer_list< int64 > dim_sizes)` {#tensorflow_TensorShape_TensorShape}
#### `tensorflow::TensorShape::TensorShape(const TensorShapeProto &proto)` {#tensorflow_TensorShape_TensorShape}
REQUIRES: `IsValid(proto)`
#### `tensorflow::TensorShape::TensorShape()` {#tensorflow_TensorShape_TensorShape}
Create a tensor shape with no dimensions and one element, which you can then call ` AddDim() ` on.
#### `tensorflow::TensorShape::~TensorShape()` {#tensorflow_TensorShape_TensorShape}
#### `tensorflow::TensorShape::TensorShape(const TensorShape &b)` {#tensorflow_TensorShape_TensorShape}
Copy the specified shape.
#### `void tensorflow::TensorShape::operator=(const TensorShape &b)` {#void_tensorflow_TensorShape_operator_}
#### `tensorflow::TensorShape::TensorShape(TensorShape &&b)` {#tensorflow_TensorShape_TensorShape}
Move the specified shape. After moving, is safe for destruction and.
#### `void tensorflow::TensorShape::operator=(TensorShape &&b)` {#void_tensorflow_TensorShape_operator_}
#### `void tensorflow::TensorShape::Clear()` {#void_tensorflow_TensorShape_Clear}
Clear a tensor shape.
#### `void tensorflow::TensorShape::AddDim(int64 size)` {#void_tensorflow_TensorShape_AddDim}
Add a dimension to the end ("inner-most"). REQUIRES: `size >= 0`
#### `void tensorflow::TensorShape::AppendShape(const TensorShape &shape)` {#void_tensorflow_TensorShape_AppendShape}
Appends all the dimensions from `shape`.
#### `void tensorflow::TensorShape::InsertDim(int d, int64 size)` {#void_tensorflow_TensorShape_InsertDim}
Insert a dimension somewhere in the ` TensorShape `. REQUIRES: `0 <= d <= dims() ` REQUIRES: `size >= 0`
#### `void tensorflow::TensorShape::set_dim(int d, int64 size)` {#void_tensorflow_TensorShape_set_dim}
Modifies the size of the dimension `d` to be `size` REQUIRES: `0 <= d < dims() ` REQUIRES: `size >= 0`
#### `void tensorflow::TensorShape::RemoveDim(int d)` {#void_tensorflow_TensorShape_RemoveDim}
Removes dimension `d` from the ` TensorShape `. REQUIRES: `0 <= d < dims() `
#### `int tensorflow::TensorShape::dims() const` {#int_tensorflow_TensorShape_dims}
Return the number of dimensions in the tensor.
#### `int64 tensorflow::TensorShape::dim_size(int d) const` {#int64_tensorflow_TensorShape_dim_size}
Returns the number of elements in dimension `d`. REQUIRES: `0 <= d < dims() `
#### `gtl::InlinedVector< int64, 4 > tensorflow::TensorShape::dim_sizes() const` {#gtl_InlinedVector_int64_4_tensorflow_TensorShape_dim_sizes}
Returns sizes of all dimensions.
#### `int64 tensorflow::TensorShape::num_elements() const` {#int64_tensorflow_TensorShape_num_elements}
Returns the number of elements in the tensor.
We use `int64` and not `size_t` to be compatible with `Eigen::Tensor` which uses `ptrdiff_t`.
#### `bool tensorflow::TensorShape::IsSameSize(const TensorShape &b) const` {#bool_tensorflow_TensorShape_IsSameSize}
Returns true if `*this` and `b` have the same sizes. Ignores dimension names.
#### `bool tensorflow::TensorShape::operator==(const TensorShape &b) const` {#bool_tensorflow_TensorShape_operator_}
#### `bool tensorflow::TensorShape::operator!=(const TensorShape &b) const` {#bool_tensorflow_TensorShape_operator_}
#### `void tensorflow::TensorShape::AsProto(TensorShapeProto *proto) const` {#void_tensorflow_TensorShape_AsProto}
Fill `*proto` from `*this`.
#### `Eigen::DSizes< Eigen::DenseIndex, NDIMS > tensorflow::TensorShape::AsEigenDSizes() const` {#Eigen_DSizes_Eigen_DenseIndex_NDIMS_tensorflow_TensorShape_AsEigenDSizes}
Fill `*dsizes` from `*this`.
#### `Eigen::DSizes< Eigen::DenseIndex, NDIMS > tensorflow::TensorShape::AsEigenDSizesWithPadding() const` {#Eigen_DSizes_Eigen_DenseIndex_NDIMS_tensorflow_TensorShape_AsEigenDSizesWithPadding}
Same as ` AsEigenDSizes() ` but allows for `NDIMS > dims() ` in which case we pad the rest of the sizes with 1.
#### `TensorShapeIter tensorflow::TensorShape::begin() const` {#TensorShapeIter_tensorflow_TensorShape_begin}
For iterating through the dimensions.
#### `TensorShapeIter tensorflow::TensorShape::end() const` {#TensorShapeIter_tensorflow_TensorShape_end}
#### `string tensorflow::TensorShape::DebugString() const` {#string_tensorflow_TensorShape_DebugString}
For error messages.
#### `void tensorflow::TensorShape::DumpRep() const` {#void_tensorflow_TensorShape_DumpRep}
#### `bool tensorflow::TensorShape::IsValid(const TensorShapeProto &proto)` {#bool_tensorflow_TensorShape_IsValid}
Returns `true` iff `proto` is a valid tensor shape.
#### `Status tensorflow::TensorShape::IsValidShape(const TensorShapeProto &proto)` {#Status_tensorflow_TensorShape_IsValidShape}
Returns `OK` iff `proto` is a valid tensor shape, and a descriptive error status otherwise.
#### `static constexpr int tensorflow::TensorShape::MaxDimensions()` {#static_constexpr_int_tensorflow_TensorShape_MaxDimensions}
#### `string tensorflow::TensorShape::DebugString(const TensorShapeProto &proto)` {#string_tensorflow_TensorShape_DebugString}
Same as `TensorShape(proto). DebugString() ` but doesn't crash for invalid protos.
