I am using UP AI Core X on Ubuntu 16.04 - https://up-shop.org/featured/261-up-ai-core-x.html
When I inference SSD Inception V2 model from the webcam input, I get these logs after a while:(10 min or so)
E: [xLink] [ 450217] dispatcherEventReceive:368 dispatcherEventReceive() Read failed -4 | event 0x7f0e9dd00ee0 XLINK_READ_REL_REQ E: [xLink] [ 450217] eventReader:230 eventReader stopped E: [xLink] [ 450218] XLinkReadDataWithTimeOut:1377 Event data is invalid E: [ncAPI] [ 450218] ncFifoReadElem:3313 Packet reading is failed.

For NCS, this seems to be the power issue. But I am not sure how I can resolve the power issue as the board is plugged in the mini-PCI-e slot of my PC.

Hi Shane,
I apologize for the delay in my response. I was able to run SSD Inception V2 and have not gotten a X_LINK error so far. I'm going to continue to run this for the next few hours to verify it'll run for an extended period of time.
I ran this with OpenVINO's object_detection_demo_ssd_async because I wasn't sure what you ran it with. If you can provide me with your model, I can try it on my end and see if I'm getting the same error.
Best Regards,
Sahira

Hi, Sahira.
Thanks for your reply!
Yeah, I have been using SSD_Inception_V2 model using object_detection_demo_ssd_async.py.
Cheers.

@Sahira.
Now, I am getting this error:
E: [xLink] [ 446330] dispatcherWaitEventComplete:709 waiting is timeout, sending reset remote event E: [xLink] [ 451328] dispatcherEventSend:945 Write failed header -7 | event XLINK_PING_REQ E: [xLink] [ 451329] eventSchedulerRun:585 Event sending failed E: [xLink] [ 451330] dispatcherEventReceive:368 dispatcherEventReceive() Read failed -4 | event 0x7f7ce4844ee0 XLINK_WRITE_REQ E: [xLink] [ 451330] eventReader:230 eventReader stopped E: [ncAPI] [ 451330] resetAll:348 Failed to connect to stalled device, rc: X_LINK_TIMEOUT E: [xLink] [ 451330] dispatcherEventSend:945 Write failed header -4 | event XLINK_RESET_REQ E: [xLink] [ 451330] eventSchedulerRun:585 Event sending failed
The UP AI Core X is plugged in the mini-PCI-e.
Not sure why it failed to detect?

Hi Shane,
What version of OpenVINO are you using? Below is how I converted the model and ran inference. Can you verify that your model was converted the same way.
I converted the model using the Model Optimizer with this command:
python3 mo_tf.py --input_model <path_to_model> --tensorflow_use_custom_operations_config <path_to_ssd_v2_support.json> --tensorflow_object_detection_api_pipeline_config <path_to_config_file> --data_type FP16
To run inference on the NCS2, i used this command:
./object_detecton_demo_ssd_async -i cam -m <path_to_frozen_xml> -d MYRIAD
Best Regards,
Sahira

@Sahira
- OpenVINO version: 2019.1.133
- Yeah, I use those python scripts to convert original inception v2 model.
This model has been working well for 6 months on NCS.
We switched to UP AI Core X a month ago and found this issue after running the engine for over an hour or so.
Is this due to the high temperature? I think it's pretty hot in Switzerland nowadays?
Cheers.

Hello,
@Shane, @Sahira Any updates on this?
I am encountering the exact same issue (X_LINK_ERROR) trying to run an SSD model on the Myriad X connected through mPCIe. The model runs fine when using CPU or NCS2 (USB interface).
Thanks!

Hi Shane,
I apologize for my late response.
I don't think that environment temperature is the issue here. The maximum internal temperature for the NCS is about 70°C, so as long as the NCS is not too hot, it should not be causing an disconnect error. Are you able to run inference on a different system to see if this is specific to the board you're using?
Best Regards,
Sahira
