#### `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_}





#### `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.

#### `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}
