## ```
## Copy the internal data representation of from to to. new_dims and
## num_new_dims specify the new shape of the to tensor, type specifies its
## data type. On success,status is set to TF_OK and the two tensors share the
## same data buffer.
##
## This call requires that the from tensor and the given type and shape (dims
## and num_dims) are "compatible" (i.e. they occupy the same number of bytes).
## Specifically, given from_type_size = TF_DataTypeSize(TF_TensorType(from)):
##
## ShapeElementCount(dims, num_dims) TF_DataTypeSize(type)
##
## must equal
##
## TF_TensorElementCount(from) from_type_size
##
## where TF_ShapeElementCount would be the number of elements in a tensor with
## the given shape.
##
## In addition, this function requires:
## TF_DataTypeSize(TF_TensorType(from)) != 0
## TF_DataTypeSize(type) != 0
##
## If any of the requirements are not met,status is set to
## TF_INVALID_ARGUMENT.

##
## Does not read memory more than src_len bytes beyond src.

## Destroy an options object. Graph will be deleted once no more

proc TF_GraphSetTensorShape*(graph: ptr TF_Graph; output: TF_Output; dims: ptr int64;
num_dims: cint; status: ptr TF_Status) {.importc, cdecl,

## ```
## Sets the shape of the Tensor referenced by output in graph to

status: ptr TF_Status): ptr TF_Function {.importc, cdecl,
impc_apiHdr.}
## ```
## Create a TF_Function from a TF_Graph
##
## Params:
## fn_body - the graph whose operations (or subset of whose operations) will be
## converted to TF_Function.
## fn_name - the name of the new TF_Function. Should match the operation
## name (OpDef.name) regexp [A-Z][A-Za-z0-9_.\\-/]*.
## If append_hash_to_fn_name is false, fn_name must be distinct
## from other function and operation names (at least those
## registered in graphs where this function will be used).
## append_hash_to_fn_name - Must be 0 or 1. If set to 1, the actual name
## of the function will be fn_name appended with
## '_<hash_of_this_function's_definition>'.
## If set to 0, the function's name will be fn_name.
## num_opers - num_opers contains the number of elements in the opers array
## or a special value of -1 meaning that no array is given.
## The distinction between an empty array of operations and no
## array of operations is necessary to distinguish the case of
## creating a function with no body (e.g. identity or permutation)
## and the case of creating a function whose body contains all
## the nodes in the graph (except for the automatic skipping, see
## below).
## opers - Array of operations to become the body of the function or null.
## - If no array is given (num_opers = -1), all the
## operations in fn_body will become part of the function
## except operations referenced in inputs. These operations
## must have a single output (these operations are typically
## placeholders created for the sole purpose of representing
## an input. We can relax this constraint if there are
## compelling use cases).
## - If an array is given (num_opers >= 0), all operations
## in it will become part of the function. In particular, no
## automatic skipping of dummy input operations is performed.
## ninputs - number of elements in inputs array
## inputs - array of TF_Outputs that specify the inputs to the function.
## If ninputs is zero (the function takes no inputs), inputs
## can be null. The names used for function inputs are normalized
## names of the operations (usually placeholders) pointed to by
## inputs. These operation names should start with a letter.
## Normalization will convert all letters to lowercase and
## non-alphanumeric characters to '_' to make resulting names match
## the "[a-z][a-z0-9_]*" pattern for operation argument names.
## inputs cannot contain the same tensor twice.
## noutputs - number of elements in outputs array
## outputs - array of TF_Outputs that specify the outputs of the function.
## If noutputs is zero (the function returns no outputs), outputs
## can be null. outputs can contain the same tensor more than once.
## output_names - The names of the function's outputs. output_names array
## must either have the same length as outputs
## (i.e. noutputs) or be null. In the former case,
## the names should match the regular expression for ArgDef
## names - "[a-z][a-z0-9_]*". In the latter case,
## names for outputs will be generated automatically.
## opts - various options for the function, e.g. XLA's inlining control.
## description - optional human-readable description of this function.
## status - Set to OK on success and an appropriate error on failure.
##
## Note that when the same TF_Output is listed as both an input and an output,
## the corresponding function's output will equal to this input,
## instead of the original node's output.
##
## Callers must also satisfy the following constraints:
## - inputs cannot refer to TF_Outputs within a control flow context. For
## example, one cannot use the output of "switch" node as input.
## - inputs and outputs cannot have reference types. Reference types are
## not exposed through C API and are being replaced with Resources. We support
## reference types inside function's body to support legacy code. Do not
## use them in new code.
## - Every node in the function's body must have all of its inputs (including
## control inputs). In other words, for every node in the body, each input
## must be either listed in inputs or must come from another node in
## the body. In particular, it is an error to have a control edge going from
## a node outside of the body into a node in the body. This applies to control
## edges going from nodes referenced in inputs to nodes in the body when
## the former nodes are not in the body (automatically skipped or not
## included in explicitly specified body).
##
## Returns:
## On success, a newly created TF_Function instance. It must be deleted by
## calling TF_DeleteFunction.
##
## On failure, null.

proc TF_NewServer*(proto: pointer; proto_len: uint; status: ptr TF_Status): ptr TF_Server {.
importc, cdecl, impc_apiHdr.}
## ```
## Creates a new in-process TensorFlow server configured using a serialized
## ServerDef protocol buffer provided via proto and proto_len.
##
## The server will not serve any requests until TF_ServerStart is invoked.
## The server will stop serving requests once TF_ServerStop or
## TF_DeleteServer is invoked.
## ```
proc TF_ServerStart*(server: ptr TF_Server; status: ptr TF_Status) {.importc, cdecl,
impc_apiHdr.}
## ```
## Starts an in-process TensorFlow server.
## ```
proc TF_ServerStop*(server: ptr TF_Server; status: ptr TF_Status) {.importc, cdecl,
impc_apiHdr.}
## ```
## Stops an in-process TensorFlow server.
## ```
proc TF_ServerJoin*(server: ptr TF_Server; status: ptr TF_Status) {.importc, cdecl,
impc_apiHdr.}
## ```
## Blocks until the server has been successfully stopped (via TF_ServerStop or
## TF_ServerClose).
## ```
proc TF_ServerTarget*(server: ptr TF_Server): cstring {.importc, cdecl, impc_apiHdr.}
## ```
## Returns the target string that can be provided to TF_SetTarget() to connect
## a TF_Session to server.
##
## The returned string is valid only until TF_DeleteServer is invoked.
## ```
proc TF_DeleteServer*(server: ptr TF_Server) {.importc, cdecl, impc_apiHdr.}
## ```
## Destroy an in-process TensorFlow server, frees memory. If server is running
## it will be stopped and joined.
## ```
proc TF_RegisterLogListener*(listener: proc (a1: cstring) {.cdecl.}) {.importc, cdecl,
impc_apiHdr.}
## ```
## Register a listener method that processes printed messages.
##
## If any listeners are registered, the print operator will call all listeners
## with the printed messages and immediately return without writing to the
## logs.
## ```
