| const OrtValue *const * | initializers, | ||
| size_t | initializers_num | ||
| ) |
Replace initialized Tensors with external data with the data provided in initializers.
The function will find the initialized TensorProtos with external data in the graph with the provided names and replace them with the provided tensors. The API verifies that the TensorProto being replaced has an external data reference and has the same name, dimensions and data type as its replacement. The replacement will occur before any of the optimizations take place. The data will be copied into the graph since TensorProto can't refer to the user provided buffers.
Once the model has been loaded, the OrtValue(s) added to SessionOptions instance will be removed from the internal SessionOptions copy to save memory, the user provided buffers can then be deallocated and the SessionOptions instance that refers to them can be destroyed.
| [in] | options | |
| [in] | initializer_names | Array of null terminated UTF-8 encoded strings of the initializers names. |

| const char * | name, | ||
| const OrtValue * | val | ||
| ) |
Add a pre-allocated initializer to a session.

| [in] | options | |
| [in] | name | Null terminated string of the initializer name |
| [in] | val | OrtValue containing the initializer. Its lifetime and the underlying initializer buffer must be managed by the user (created using the OrtApi::CreateTensorWithDataAsOrtValue) and it must outlive the session object to which it is added. |

Binds the OrtValue to a device which is specified by OrtMemoryInfo. You can either create an instance of OrtMemoryInfo with a device id or obtain one from the allocator that you have created/are using This is useful when one or more outputs have dynamic shapes and, it is hard to pre-allocate and bind a chunk of memory within OrtValue ahead of time.

Create an OrtArenaCfg.
Create the configuration of an arena that can eventually be used to define an arena based allocator's behavior.
Supported keys are (See https://onnxruntime.ai/docs/get-started/with-c.html for details on what the following parameters mean and how to choose these values.): "max_mem": Maximum memory that can be allocated by the arena based allocator. Use 0 for ORT to pick the best value. Default is 0. "arena_extend_strategy": 0 = kNextPowerOfTwo, 1 = kSameAsRequested. Use -1 to allow ORT to choose the default. "initial_chunk_size_bytes": (Possible) Size of the first allocation in the arena. Only relevant if arena strategy is kNextPowerOfTwo. Use -1 to allow ORT to choose the default. Ultimately, the first allocation size is determined by the allocation memory request. "max_dead_bytes_per_chunk": Threshold of unused memory in an allocated chunk of arena memory after crossing which the current chunk is chunked into 2. "initial_growth_chunk_size_bytes": (Possible) Size of the second allocation in the arena. Only relevant if arena strategy is kNextPowerOfTwo. Use -1 to allow ORT to choose the default. "max_power_of_two_extend_bytes": The maximum enxtend size if arena strategy is kNextPowerOfTwo. It is not an allocation limit, it is only a limit for extention when requested byte is less than the limit. When requested bytes is more than the limit, allocator will still return as requested. Use -1 to allow ORT to choose the default 1GB for max_power_of_two_extend_bytes. Ultimately, the allocation size is determined by the allocation memory request. Further allocation sizes are governed by the arena extend strategy.

Create an opaque (custom user defined type) OrtValue.
Constructs an OrtValue that contains a value of non-standard type created for experiments or while awaiting standardization. OrtValue in this case would contain an internal representation of the Opaque type. Opaque types are distinguished from each other by two strings 1) domain and 2) type name. The combination of the two must be unique, so the type representation is properly identified internally. The combination must be properly registered from within ORT at both compile/run time or by another API.
To construct the OrtValue pass domain and type names, also a pointer to a data container the type of which must be known to both ORT and the client program. That data container may or may not match the internal representation of the Opaque type. The sizeof(data_container) is passed for verification purposes.

This is useful when used in conjunction with OrtApi::AddInitializer which injects shared initializer info into sessions. Wherever possible, the pre-packed versions of these shared initializers are cached in this container so that multiple sessions can just re-use these instead of duplicating these in memory.

OrtSessionOptionsAppendExecutionProvider_CPU
OrtSessionOptionsAppendExecutionProvider_CUDA
OrtSessionOptionsAppendExecutionProvider_(remaining providers...)
The order they are called indicates the preference order as well. In other words call this method on your most preferred execution provider first followed by the less preferred ones. If none are called Ort will use its internal CPU execution provider.

Create an OrtValue with a sparse tensor. This is the first step. Next, use Use<Format>Indices() functions to supply sparse tensor with format specific indices data and set its sparse format to a specific enum value. This will not perform memory allocations. It will use supplied user buffer which should outlive the created sparse tensor. Use OrtApi::ReleaseValue to destroy the sparse tensor. It would not release the supplied values buffer. This function can not be used to map strings from the user allocated memory. Strings must always be copied and have UTF-8 encoding. Therefore, use OrtApi::CreateSparseTensorAsOrtValue above and then fill it with data using appropriate Make*() function.

| OrtStatus * OrtApi::RegisterCustomOpsLibrary | ( | OrtSessionOptions * | options, |

Registers custom ops from a shared library.
Loads a shared library (dll on windows, so on linux, etc) named 'library_path' and looks for this entry point: OrtStatus* RegisterCustomOps(OrtSessionOptions * options, const OrtApiBase* api); It then passes in the provided session options to this function along with the api base. The handle to the loaded library is returned in library_handle. It can be freed by the caller after all sessions using the passed in session options are destroyed, or if an error occurs and it is non null.
| [in] | options | |
| [in] | library_path | |
| [out] | library_handle | OS specific handle to the loaded library (Use FreeLibrary on Windows, dlclose on Linux, etc.. to unload) |
| OrtStatus * OrtApi::RegisterCustomOpsLibrary_V2 | ( | OrtSessionOptions * | options, |

| ) |
Register custom ops from a shared library.
Loads a shared library (.dll on windows, .so on linux, etc) named 'library_name' and looks for this entry point: OrtStatus* RegisterCustomOps(OrtSessionOptions * options, const OrtApiBase* api); It then passes in the provided session options to this function along with the api base.
The handle to the loaded library is automatically released by ORT when the last OrtSession that references the library handle is released. If no OrtSession is created, then the library handle is released when the provided OrtSessionOptions is released.
| [in] | options | The session options. |
| [in] | library_name | The name of the shared library to load and register. Refer to OS-specific dynamic library loading utilities (e.g., LoadLibraryEx on Windows or dlopen on Linux/MacOS) for information on the format of library names and search paths. |
| OrtStatus * OrtApi::RegisterCustomOpsUsingFunction | ( | OrtSessionOptions * | options, |
| const char * | registration_func_name | ||
| ) |
Register custom ops by calling a RegisterCustomOpsFn function.
Searches for registration_func_name and if found calls it.
The library containing the function must either be linked against or previously loaded by the executable.
If you want ONNX Runtime to load the library and manage its lifetime, use RegisterCustomOpsLibrary_V2.
RegisterCustomOpsUsingFunction can be used in scenarios where it may not be possible for ONNX Runtime to load the library from a path. e.g. mobile platforms where the library must be linked into the app.
The registration function must have the signature of RegisterCustomOpsFn: OrtStatus* (fn)(OrtSessionOptions options, const OrtApiBase* api);
See https://onnxruntime.ai/docs/reference/operators/add-custom-op.html for details on how the registration function should be implemented.
| [in] | options | OrtSessionOptions that is passed through as the first argument in the call to the registration function. |
| [in] | registration_func_name | Name of registration function to use. |
