C++ tutorial build does not seem to complete #195

Open mrohera opened 5 years ago

mrohera commented 5 years ago

Following the instructions here: https://microsoft.github.io/ELL/tutorials/Getting-started-with-image-classification-in-cpp/, I am seeing that the build is essentially stalled and I have to CTRL+C to kill the build. Could you kindly suggest what am I missing?

python /home/marohera/git/ell/ELL/tools/wrap/wrap.py --model_file model.ell --language cpp --outdir model              
copy "/home/marohera/git/ell/ELL/CMake/OpenBLASSetup.cmake" "model/OpenBLASSetup.cmake"

I've seen this on a PC running an older Intel "sandybridge" CPU. Seems LLVM is getting stuck. The bug is being investigated.

Try running this to produce the required model.o object file:

d:/git/ELL/ELL/build/bin/release/compile -imap model.ell -cfn Predict -cmn model --target host -od model --fuseLinearOps True --optimizeReorderDataNodes True --header --blas true --optimize true --objectCode

Thanks for getting back! After following the tutorial I created the build dir and ran cmake. I do not have the compile executable as per your comment above. If you have a writeup to generate a model.o that is perfect and exactly what I am after.

Hi, Is the compile executable perhaps in /homne/marohera/git/ell/ELL/build/bin? (without the 'release')?

mrohera commented 5 years ago

Found it under /ELL/build/bin sorry it was my bad, I issued the command and looks like it worked. Thanks Chris.

Just FYI here is the output of /proc/cpuinfo/

cat /proc/cpuinfo
processor   : 0
vendor_id   : GenuineIntel
cpu family  : 6
model       : 58
model name  : Intel(R) Core(TM) i7-3667U CPU @ 2.00GHz

This is the Intel's product page for this CPU: https://ark.intel.com/products/64898/Intel-Core-i7-3667U-Processor-4M-Cache-up-to-3-20-GHz-

Oh, and be sure to add "--target pi3" to the compile command line if you plan to run that model on your raspberry pi.
