4.2.2 Model Load/Unload API

hbDNNInitializeFromFiles()

【Function Prototype】

int32_t hbDNNInitializeFromFiles(hbPackedDNNHandle_t *packedDNNHandle, const char **modelFileNames, int32_t modelFileCount)

【Function Description】

Create and initialize packedDNNHandle from files. The returned packedDNNHandle can be used across functions and threads.

【Parameters】

• [out] packedDNNHandle: D-Robotics DNN handle that points to multiple models.
• [in] modelFileNames: Path of model files.
• [in] modelFileCount: Number of model files.

【Return Type】

• Return 0 if the API is executed successfully, otherwise execution fails.

hbDNNInitializeFromDDR()

【Function Prototype】

int32_t hbDNNInitializeFromDDR(hbPackedDNNHandle_t *packedDNNHandle, const void **modelData, int32_t *modelDataLengths, int32_t modelDataCount)

【Function Description】

Create and initialize packedDNNHandle from DDR. The returned packedDNNHandle can be used across functions and threads.

【Parameters】

• [out] packedDNNHandle: D-Robotics DNN handle that points to multiple models.
• [in] modelData: Pointer to model data.
• [in] modelDataLengths: Length of model data.
• [in] modelDataCount: Number of model data.

【Return Type】

• Return 0 if the API is executed successfully, otherwise execution fails.

hbDNNRelease()

【Function Prototype】

int32_t hbDNNRelease(hbPackedDNNHandle_t packedDNNHandle)

【Description】

Release the model pointed by packedDNNHandle.

【Parameters】

• [in] packedDNNHandle: D-Robotics DNN handle pointing to multiple models.

【Return Type】

• Return 0 if the API is executed successfully, otherwise indicate failure.
