Hello!
I am working on integrating a TI Deep Learning ( https://training.ti.com/texas-instruments-deep-learning-tidl-overview ) model into an OpenVX (TIOVX) based application, the inference with TIDL itself works, as well as the application itself also, but when I run both together the application crashes when initializing the model with TIDL.
To be precise, we integrated our model as a custom OpenVX kernel ( https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/tiovx/docs/user_guide/TIOVX_TARGET_KERNEL.html ) and initialized the TIDL model inside the kernel and would also run inside the kernel. When running the Graph we get the following error message:
2171734.545072 s: VX_ZONE_ERROR:[tivxIpcSendMsg:96] OpenVX send notification failed
2171734.545105 s: VX_ZONE_ERROR:[tivxObjDescSend:272] tivxIpcSendMsg failed

2171734.545266 s: VX_ZONE_ERROR:[vxProcessGraph:760] wait graph failed
I suspect this might be caused by multiple vx_contexts, where the TIDL library does not know about the application it is running and therefore creates its own vx_context. Problem being, that there is (at least according to my knowledge) no public API to manually set the proper context for the TI DL lib to use.
Does anyone know how we could get this running? Or is the problem possibly somewhere else?
Best regards,
Robert!
