Cannot load semantic segmentation model to NCS from Raspbian

I am loading semantic-segmentation-adas-0001-fp16.xml to NCS2 from Raspbian 2 with l_openvino_toolkit_raspbi_p_2019.1.144.tgz.

And the standard segmentation_sample fails:

[ INFO ] Loading model to the plugin
E: [xLink] [    441743] XLinkOpenStream:1140    Got wrong package from device, error code = X_LINK_OUT_OF_MEMORY

The smaller model road-segmentation-adas-0001.bin loaded without any problems.

Dear Stantin,

It looks like you are on an old version -  l_openvino_toolkit_raspbi_p_2019.1.144.tgz. Please upgrade to the latest version. What you are experiencing is an out of memory error, since the NCS2 device does sometimes bump into physical memory limitations with certain huge models. The capacity to handle larger models has been greatly improved in 2019R2 though - can you try again after upgrading ?

Thanks,

Shubha

Hi Shubha,

I've run into the same problem with the road-segmentation-adas-0001 loading and running no worries, but the semantic-segmentation-adas-0001 model is running out of memory.

I'm running the current release of openvino raspbian 2019.3.334. Is 13MB the size limit that the NCS2 can load?

Are there any other work arounds you can sugest?

Thanks,

Tim
