Changing resolutions causes Read failed

[idata]

Hi, On OpenVINO,

We convert the model using mo.py into different input resolutions, and during inference of some resolutions get the error below,tested both with Movidius and Movidius X (Neural stick versions one and two),usually on Movidius (stick version one) there is no such error, and we do get it on Movidius X (stick version two)e.g on Movidius X resolutions 128 X 128 X 3 and 256 X 256 X 3 work, but we get this error on 192 X 192 X 3, and every resolution above 256 X 256 X 3.whereas on Movidius it works on all of the resolutions, below 480 X 480 X 3 (and we get this error on 480 X 480 X 3).(the behavior is consistent, if there's an error on some resolution it always appear).

BTW on NCSDK 2, we got a similar error ("Read failed -4") when approaching the limit of resources allocation (yet not crossing it),

Maybe it's resources related?Is there something we can do?

Full error text is (when running in async fashion in a loop 5 times over the same input):

E: [xLink] [ 0] dispatcherEventReceive:308 dispatcherEventReceive() Read failed -4 | event 0x7f2825bb5ef0 USB_READ_REL_RESP

Hi @blinking,

Thanks for reaching out. I'd suggest to report the problem you have experienced with OpenVINO Toolkit and NCS2 in the OpenVINO forums https://software.intel.com/en-us/forums/computer-vision.

As far as the problem you mentioned with the NCSDK2, could you provide more details of your current setup (Host OS, VM?, Neural Compute Stick 1?, USB powered hub?, etc.)? Any additional information that could help me reproduce the problem would be great.

Regards,

Luis
