[watchdog] [ 0] sendPingMessage:164 Failed send ping message: X_LINK_ERROR

@Sahira_at_Intel

Could you do me a favor to find the root cause from the below error message? I got it from my UP-BOARD computer (Win10 1709) with NCS2 (through additional power supply USB3.0 Y cable) and OpenVINO 2018 R5.0.1.
My code is basically derived from the C:\Intel\computer_vision_sdk\inference_engine\samples\python_samples\object_detection_demo_yolov3.py sample code with a few modifications, and I saw the error with running it continuously 1~2 hours.

1) Receiving IPCAM streaming frames (30fps) as the input source rather than using Webcam in a dedicated Python worker thread (i.e. threading.Thread)
2) The IEPlugin and IENetwork related objects are all being instantiated/operated in that dedicated worker thread rather than the main thread.
3) Main thread is used for rendering the object detection result. It communicates with the worker thread through a synchronized queue.

I suspected it's related to NCS2 overheating issue but now I don't think so. Last night, I tried to isolate all IEPlugin and IENetwork related code into a Python worker process (i.e. multiprocessing.Process) and communicate with it through IPC (i.e. multiprocessing.Pipe). It's very weird that now I'm not able to reproduce the error message after running the job 8 hours. Haha!

As you've known there are some other people seeing the same error code in https://ncsforum.movidius.com/discussion/1106/ncs-temperature-issue
Could you still escalate the issue to RD core team? I'm wondering to know what the error message mean. Thank you.

  • Unfortunately, the error still can be reproduced after running 12 hours even isolating all IEPlugin and IENetwork related code into a Python worker process (i.e. multiprocessing.Process) and communicate with it through IPC (i.e. multiprocessing.Pipe).

  • Hi @lilohuang

    I was able to run a test on this issue. My setup: used an Intel NUC (Hades Canyon NUC8I7HVK, w/ 32 GB memory). running windows 10, and openvino R5.0.1. I ran the object detection for 4 - 5 hours and did not run into that error. The internal temperature of the NCS2 was ~50 C (maximum temperature is ~70 C for reference). So, I don't think this error is due to overheating. You said you were getting additional power through a USB y cable, so perhaps the cable is faulty? (That's what the Failed send ping message: X_LINK_ERROR[0m is telling me). Are you able to try on a different system and plug straight into the USB port if the UP board doesn't supply enough power by itself?

    Best Regards,
    Sahira

  • @Sahira_at_Intel
    Hi, I got 2 similar problems.
    1. While I'm using NCS2 to do face recognition, I touched the NCS2 to feel the temperature and got an electric shock, and similar warning message showed as @lilohuang got. Is there any problem with ESD...?
    2. Running the face recognition in async mode continuously 2 hours and it returns nothing. https://software.intel.com/en-us/forums/computer-vision/topic/805853
    I'm experimenting on a laptop with i7-7700k CPU, Ubuntu16.04LTS, using OpenVINO 2018 R5.0.1 and one NCS2

  • @Sahira_at_Intel In fact, I've bought a new USB HUB with additional AC power instead of Y-cable after March, 9. Unfortunately, the error is still there with long running (>12 hours, 30 fps, async mode). I suspect it's a software bug (MYRIAD driver bug?) rather than hardware overheating issue. May I know how you get the internal temperature of the NCS2? through an internal debugging flag?

    Sorry, I'm a programmer mainly on Mac OS X, I only have one UP-BOARD system to run the stress test. Of course, I will consider to spend more money to buy a INTEL NUC same as your spec if it indeed can fix the issue. If the power supply of NCS2 is critical, and then it conflicts with my understanding of Intel promotion video which claims NCS2 only requiring low power consumption.

    Could you try to run TinyYOLOv3 (30 fps, async mode) over than 24 hours? Reading another post to see some update from other people. https://software.intel.com/en-us/forums/computer-vision/topic/805853 I believe I'm not the only one person suffered this problem. Thanks for your strong support!

  • @Sahira_at_Intel Tonight, I tried to install Windows 10 (1809, 30 fps, TinyYoloV3, not Yolov3, async mode) on my Mac OS X through Parallel Desktop 14, and then I plugged another NCS2 device (I have 3 NCS2 devices) DIRECTLY to my MacBook Pro USB3 port. It worked perfectly but an error occurred after running object detection 30 mins. Sorry I forgot to mention that I also saw the "Duplicate id detected" error string on my UP-BOARD computer. I believe it's NOT caused by faulty USB cable because the error is still occurred even w/o USB cable. I can help you to collect debug information if there is a debug mode can be turned on. Thank you!

  • Hi @lilohuang @FREEMAN123

    I have been running the object_detection_demo_yolov3_async on Ubuntu 16.04 with OpenVINO R5.0.1 for 24 hours now. When I started the demo, I hit the tab key to start "True Async", are you doing the same? My Neural Compute Stick 2 is connected to a powered USB Hub staying around 48 C (Temperature taken with a IR Thermometer).

    Could you share a link to which yolo v3 model you are using? Are you using the tiny or full yolo model?

    Regards,
    Jesus

  • @Jesus_at_Intel Thank you for your response. As I mentioned earlier, my code is basically derived from C:\Intel\computer_vision_sdk\inference_engine\samples\python_samples\object_detection_demo_yolov3.py from OpenVINO R5.0.1 rather than Intel OpenVino YOLOv3 C++ sample code. A few code modification on object_detection_demo_yolov3.py is required for parsing TinyYOLOv3 result, the model file is simply converted from a regular TinyYOLOv3 weight file for MYRIAD (FP16).

    I can also reproduce the error through PINTO's repo. https://github.com/PINTO0309/OpenVINO-YoloV3 , using the converted model by PINTO under lrmodels/tiny-YoloV3/FP16/, and running openvino_tiny-yolov3_test.py even with synchronous mode (i.e. calling exec_net.infer()) on Windows 10 (1709) after running 12~16 hours. Of course, using Asynchronous mode (i.e. calling exec_net.start_async()) like Intel's object_detection_demo_yolov3.py did can increase the error reproducibility.

  • @Jesus_at_Intel @Sahira_at_Intel

    Please applying below diff patch onto C:\Intel\computer_vision_sdk\inference_engine\samples\python_samples\object_detection_demo_yolov3.py from OpenVINO R5.0.1, and downloading the pre-converted TinyYOLOv3 model by PINTO via https://github.com/PINTO0309/OpenVINO-YoloV3/tree/master/lrmodels/tiny-YoloV3/FP16/download_tiny-yolov3lrFP16.sh The previous error I mentioned is repeatable after a long running test through it. Thank you.

    BTW, Intel's object_detection_demo_yolov3.py sample code has an accuracy issue like I mentioned in https://github.com/PINTO0309/OpenVINO-YoloV3/issues/13#issuecomment-468203337, this issue has been fixed in PINTO's repo. You can ignore the accuracy issue while you reproducing the crash bug.

  • Today, I got the same error by using C:\Intel\computer_vision_sdk_2018.5.456\deployment_tools\inference_engine\samples\python_samples\object_detection_demo_ssd_async.py with pretrained model C:\Intel\computer_vision_sdk_2018.5.456\deployment_tools\intel_models\person-vehicle-bike-detection-crossroad-0078\FP16\person-vehicle-bike-detection-crossroad-0078.xml on my UP-BOARD with NCS2 after few hours. I believe INTEL NCS2 is NOT ONLY compatible with INTEL NUC. Could your team find some OTHER computers to test NCS2 device rather than INTEL NUC? Thanks.
