Custom Yolov3-tiny ota model update, segmentation fault

[mehmetduman]

Hardware Platform (Jetson / GPU) :- Jetson Nano
• DeepStream Version :- 5.0
• JetPack Version (valid for Jetson only) - 4.4 [L4T 32.4.3]
• TensorRT Version :- 7.1.3.0
• CUDA : 10.2.89

I am working on the deepstream-test5 app to try out the OTA functionality on custom yolov3-tiny model. I tried the test file by just adding a white space at the end of the file and saved it, and it worked perfect (/opt/nvidia/deepstream/deepstream-5.0/sources/apps/sample_apps/deepstream-test5/configs/test5_ota_override_config.txt)

When I tried my code, the deepstream-test5-app detects a change in the ota override file, and update the model succesfully, but than i get ‘Segmentation fault (core dumped)’. I used the same custom yolov3-tiny model engine file i run on deepstream-test5-app and just add a white space on ota override config file.

Hi,

We are trying to reproduce this issue.
Will update more information with you later.

[AastaLLL]

Hi,

We try to reproduce this issue but the OTA function works good in our environment.
Would you mind to try if the replaced model can work with deepstream correctly first?

Thanks.

[mehmetduman]

Thank you for the quick response.

I tried the Primary Detector caffe model (/opt/nvidia/deepstream/deepstream-5.0/samples/models/Primary_Detector) and ota worked perfectly fine when I add a whitespace on override file (2)

Then I downloaded yolov3-tiny.cfg and yolov3-tiny.weights files by following README (/opt/nvidia/deepstream/deepstream-5.0/sources/objectDetector_Yolo/README). Updated class number (static const int NUM_CLASSES_YOLO = 80;) and compiled it , and created .so shared file.

• $ export CUDA_VER=10.2
• $ make -C nvdsinfer_custom_impl_Yolo

I moved all files (.cfg, .weights, .label and .so file) into same folder and run deepstream-test5-app with -o option. When I changed the override file, deepstream catched the changes, but stopped by segmentation error (1)

Please let me know if you need more information and thanks for your help.

I also tried YoloV3 and got same Segmentation fault …

The caffe model works, but yolov3 and yolov3-tiny doesn’t !

Additional tests with Docker (nvcr.io/nvidia/deepstream-l4t:5.0-20.07-iot) ;

I thought, it would make sense to do some test in container to eliminate environment issues.

I ran Yolov3 (80 class), Yolov3-Tiny (80 class) and caffe model (/opt/nvidia/deepstream/deepstream-5.0/samples/models/Primary_Detector) on docker container and all three models ran perfect.

When I tried the OTA with those 3 models, all three started and did inferences until I update override file.The Yolov3 and Yolov3-Tiny models had same issue as above, after updated the model raised Segmentation fault. The Caffe model updated the OTA model and ran without any issue.

It looks like OTA has some issues with YoloV3 models.

[AastaLLL]

Hi,

Thanks for the update.

We try YOLOv3-tiny in a similar way as objectDetector_Yolo and it works.
Will check if anything different between our testing and give you an update.

Thanks.

[AastaLLL]

Hi,

We try to reproduce this issue with our deepstream container but the OTA process works good in our environment.

May I know the class number of original YOLOv3_tiny and OTA YOLOv3_tiny first?
If the class number changes, the OTA will not work since the network architecture need to be updated.

We test this with default #class=8 (both model) and it can work correctly.

Thanks.

[mehmetduman]

Hi,

First, I used 2 custom YoloV3-Tiny custom models which both has same 2 classes and same architecture, and and got segmentation fault.

Then, I used official YoloV3-Tiny.weights model which has 80 classes and got segmentation fault

• Downloaded by following README in (/opt/nvidia/deepstream/deepstream-5.0/sources/objectDetector_Yolo/README)

Then, I used official YoloV3.weights model which has 80 classes and got segmentation fault

• Downloaded by following README in (/opt/nvidia/deepstream/deepstream-5.0/sources/objectDetector_Yolo/README)

Then, I said maybe my Jetson Nano environment has some issue and I tried the official YoloV3 and YoloV3-Tiny models on Docker container and got same segmentation fault.

How I created the YoloV3/YoloV3-Tiny .so shared library:

Followed the README in (in (/opt/nvidia/deepstream/deepstream-5.0/sources/objectDetector_Yolo/README)

• static const int NUM_CLASSES_YOLO = 80
• $ export CUDA_VER=10.2
• $ make -C nvdsinfer_custom_impl_Yolo

Run Process

• Run the deepstream-test5-app,
  deepstream-test5-app -c deepstream_app_config_6source_cartruck.txt -t -o test5_ota_override_config.txt

• The app applies the OTA update at starting just before the “Runtime commands” (Please see below output).

• I add a white-space to the override file, use the same model that I run the deepstream-test5-app and save it

• The deepstream app catch the changes on override file and start to model update (Please see below output)

• The deepstream app complete the model update (Please see below output)

• Raises Segmentation fault.

Hi,

Thanks for your detail update.
We will try this on another device to see if we can reproduce this issue or not.

Thanks.

[AastaLLL]

Hi,

We found this may be a memory issue.
Would you mind to check the memory status with tegrastats when running the OTA process?

$ sudo tegrastats

Thanks.

[mehmetduman]

Hi,

Here are the $ sudo tegrastats result. I also added an Ubuntu internal error which I got first time. Hope these would help to resolve the problem

[mehmetduman]

cuDNN version:

[AastaLLL]

Hi,

Based on your tegrastats log here, the failure may cause by out of memory.

Would you mind to add 4G swap space and try it again?

Trt_convert converter.convert() gets killed without errors

Hi, Would you mind to create some swap space to see if help? You will need an extra space for the swap file. Ex. sudo fallocate -l 8G [/media/mySSD/swapfile] sudo chmod 600 [/media/mySSD/swapfile] sudo mkswap [/media/mySSD/swapfile] sudo /bin/sh -c 'echo "[/media/mySSD/swapfile] \t none \t swap \t defaults \t 0 \t 0" >> /etc/fstab' sudo swapon -a Thanks.

Thanks.

[mehmetduman]

Hi, I have added 8GB swap space, but still getting segmentation fault (core dumped)

[AastaLLL]

Hi,

Thanks for your testing.

We are discussing the possible cause internally.
Will share more information with you later.

[AastaLLL]

Hi,

Thanks for your patience.

It seems that some steps are incorrect in our previous testing.
Now, we can reproduce this error in our environment.

We are check this with our internal team.
Will update more information with you once we got a feedback.

Thanks.

[AastaLLL]

Hi,

Thanks for your patience.

The root cause of segmentation fault is from the custom parser lib.
Please noted that OTA is an alpha feature. We will provide a fix in a future release.

Thanks.
