Unable to convert segmentation model using BlobConverter

tarocal

Hello,

I am trying to use the BlobConverter (http://69.164.214.171:8080/) to download a segmentation model (instance-segmentation-security-1040) as a blob file. But when I visit the site, my GPU usage skipes, and I cant convert/download anything else. The conversion 'happens' for a long time and then my browser times out.

I tried to replicate the issue with a friend's computer (our IPs are similar but not the same), they also noticed high GPU usage. Is something happening on the server side? Is one of my (failed) old tasks running somehow? Is there a place where I can download the converted models (shave count not a problem) as blobs?

P.S. to erik: if you happen to read this, thanks for the quick response last week on Friday (Depth error in MobileNet).

Thanks to any solution in advance.

Hi tarocal ,

BlobConverter is working, but for some reason it returns 400 Bad Request when trying to convert instance-segmentation-security-1040 and the response body is so large (131 MB) it's breaking the client. Will investigate it further and circle back

The response is so large because the compile command fails, constantly printing this error message

: [xLinkUsb] [    645631] [myriad_compile] usb_find_device_with_bcd:266	Library has not been initialized when loaded

Will now check why it's happening in this model and not in the others and how to solve it

EDIT
It seems to be affecting also face-detection-retail-0004

EDIT 2
Although it seems serious, this is just a warning message (per this issue). So will dig further why the compilation fails and add a TODO to filter out these warnings from error messages sent to client

The compilation of instance-segmentation-security-1040 fails with the error shown below.

DynamicToStaticShape transformation encountered dynamic node Pad_968 of type Pad ver. 1, but only [Ceiling ver. 0, Clamp ver. 0, Concat ver. 0, Convert ver. 0, Exp ver. 0, ExpGatherElements ver. 0, Floor ver. 0, Log ver. 0, MatMul ver. 0, Relu ver. 0, ...] types are supported for dynamic nodes

I'll make sure to update blobconverter so that we can see this error in the UI (as it should be happening) and then investigate the issue itself

I found a webpage where different models support is listed and it seems that instance-segmentation-security-1040 is not supported on MyriadX devices

support

https://openvino.jp/openvino-2021-3-openmodelzoo-list/ (site is in Japanese)

EDIT
I asked them on Twitter (https://twitter.com/OpenvinoJ) if I can get more info about how they test these models. Maybe we could leverage their findings and show models that are only supported on MyriadX

Just added a PR and after deployment, the BlobConverter should output a correct error modal
