Public Static Functions

static inline Status Load(const void *model_data, size_t data_size, ModelType model_type, Graph *graph, const Key &dec_key = {}, const std::string &dec_mode = kDecModeAesGcm)

Loads a model file from memory buffer.

参数

  • model_data – [in] A buffer filled by model file.

  • data_size – [in] The size of the buffer.

  • model_type – [in] The Type of model file, options are ModelType::kMindIR, ModelType::kOM.

  • graph – [out] The output parameter, an object saves graph data.

  • dec_key – [in] The decryption key, key length is 16, 24, or 32. Not supported on MindSpore Lite.

  • dec_mode – [in] The decryption mode, optional options are AES-GCM, AES-CBC. Not supported on MindSpore Lite.

返回

Status.
