Error Compiling Examples

idata — Wed, 24 Oct 2018 12:22:24 GMT

When trying to compile any example using commands like:

making compile

mvNCCompile -w squeezenet_v1.0.caffemodel -s 12 deploy.prototxt

I get the following error:

Makefile:88: recipe for target 'compile' failed

make: *** [compile] Illegal instruction (core dumped)

I have

jose@computer:~/ncsdk/examples/caffe/SqueezeNet$ echo $PYTHONPATH

:/opt/movidius/caffe/python

@JosePerez What type of machine are you using the NCSDK on?

Hi @Tome_at_Intel I am also getting this when the make file for Facenet tries to compile the graph on Ubuntu 16.04 & 18.04 (On an UP Squared). I had seen similar errors with conflicting TF versions before so decided to try upgrade to 18.04 and reinstall everything but no change. ( I modified the NCSDK2 installer to allow 1804)

Running Facenet makefile:

Unzipping.

@AdamMiltonBarker Which CPU does your Up Squared board use? If it is an Atom CPU, it seems like the Intel Atom processors don't have AVX support and for TensorFlow 1.6 and higher, release binaries are prebuilt with AVX instructions. One option is to use TF 1.5 or below.

Another option that may work is to build TensorFlow yourself using docker: https://github.com/hadim/docker-tensorflow-builder

Intel NUC NUC5CPYH with 8 Gb of RAM. Running a new installation of Ubuntu 16.04

@Tome_at_Intel Will I be able to run in this platform?

Re: Error Compiling Examples

@JosePerez You should be able to run it with that platform.

Any clue to solve this issue? As I mentioned, this is a brand new installation of Ubuntu and then the movidius installation. It is not makeany sence to have any error if we only have this installation from the scratch

@JosePerez I was mistaken, the Intel Celeron N3050 processor that comes with the Intel NUC NUC5CPYH doesn't have support for AVX instructions. As such the TensorFlow binaries that were prebuilt with AVX instructions (with pip) won't work on your machine. More information at https://github.com/tensorflow/tensorflow/issues/23520.
