PROCESSOR-SDK-AM57X: TIDL SSD example application runs with problems when using own model

Other Parts Discussed in Thread: AM5728, AM5749

Hi，

I have trained a mobilenet based SSD on VOC dataset, the framework I used is caffe-jacinto(without sparse trainning step). The caffemodel have been successfully imported to what TIDL surpports,and the network have been seperated to two layergroups just as the ssd models in ti-processor-sdk-linux-am57xx-evm-05.01.00.11/linux-devkit/sysroots/armv7ahf-neon-linux-gnueabi/usr/share/ti/tidl/examples/test/testvecs/config/tidl_models.

I tried to use the application in ti-processor-sdk-linux-am57xx-evm-05.01.00.11/linux-devkit/sysroots/armv7ahf-neon-linux-gnueabi/usr/share/ti/tidl/examples/ssd_multibox, the default configuration wroks just fine on AM57xEVM and I can get the correct output. But when I change the confguration file to point to my own model bin file, the app just can't execut successfully. I have add some print impromation,and found that eop->ProcessFrameWait() can't get a process finished signal from eop->ProcessFrameStartAsync(), so the app just stuck in process.

I don't know why this happened.mabye there are wrongs in my imported model or other reasons have caused this problem?

Hi,

Can you please share network binary, parameter binary and configuration file to reproduce/analyze the problem at our end?

Hi,

Thanks for sharing the file. We will investigate into this and get back. Can you please confirm which exact AM57x EVM you are using? Is it AM5728 GP EVM or AM5749 IDK EVM.

Regards,
Manisha

Hi，
The platform I use is AM5728 GP EVM, but I found that there are 4 EVEs on board.

Hi,

We are investigating the issue. The fix will be available in Processor SDK release version 5.3 scheduled end of 1Q, 2019. I am closing this thread for now.

Hi,

Can you please share the detail steps to recreate this hang scenario at our end? Meanwhile I recommend you to check the constrains on layers parameters and verify you are not breaking any of the constrains on these parameters.

Please use TIDL network viewer to check the structure of the converted network. Refer to link below on usage of the viewer-tool. Compare the parameters with the listed constrain and check if any constrains are violated. If they do, please fix it and re-run the converted model.

Hi,

We found some limitations in TIDL library causing this hang. The fix for this issue will be available in Proc SDK 5.3 release, scheduled in end of March, 2019.
