OPENCL initialization failed - Without GPU support

[ymotola]

I am working on a iMX6 quad core cpu with Vivante GC2000 GPU.
After building CaffeOnAcl according to installation instructions I try to run the classification example as shown.
No matter what I do, I keep getting:
"OPENCL initialization failed"

I am working with OpenCL and I know it is working properly.
The tests in the CaffeOnAcl - Unit tests also throw segmentation fault after a few successful tasks.
I already Compiled protobuf from scratch and removed opencl_dnn library from my /usr/lib (two solutions that where suggested in some forums) but nothing helps.

Please help!!!

System configuration

Operating system: Yocto - Poky 1.8.2
Compiler: arm-poky-linux-gnueabi-gcc
CUDA version (if applicable): none
CUDNN version (if applicable): none
BLAS: OpenBlas
Python or MATLAB version (for pycaffe and matcaffe respectively): Python 2.7

@ymotola You may run Arm Compute Library test first to check if it support Vivante GC2000 GPU.

Hi Joey,
Is it possible to use only NEON?
What should I do except for building the ACL with opencl=0 and the CaffeOnACL with USE_CPU=1?

Hello,

@honggui Please re-open this thread.
I compiled the CaffeOnACL with CPU_ONLY=1 but the ARM Compute library with OpenCL as suggested in other posts https://github.com/OAID/caffeOnACL/issues/8 otherwise it won't compile.
Even tough, I still get "OPENCL initialization failed" when I try to run the tests, why?

Maybe it is not related to the GPU...
When I try to run the classification.bin sample I get the following:

If I run "unit_tests/test" from CaffeOnACL with GDB, I get segmentation fault from here:

I can't get a trace further than that.

@ymotola this version need Arm Compute Library compile with OpenCL, Next version will support Neon only with compile flag.
From you call dump:

do you have the file bvlc_reference_caffenet.caffemodel in models/bvlc_reference_caffenet?

[ymotola]

I have compiled ACL with OpenCL, this was the only way I could compile the CaffeOnACL.
I do have this model.
Whats are all those errors about HDF5?

[joey2014]

at least , caffe report it can't open the file
F0118 11:56:23.967454 13761 net.cpp:799] Check failed: file_hid >= 0 (-1 vs. 0) Couldn't open models/bvlc_reference_caffenet/bvlc_reference_caffenet.caffemodel

from net.cpp:799
template
void Net::CopyTrainedLayersFromHDF5(const string trained_filename) {
#ifdef USE_HDF5
hid_t file_hid = H5Fopen(trained_filename.c_str(), H5F_ACC_RDONLY,
H5P_DEFAULT);
CHECK_GE(file_hid, 0) << "Couldn't open " << trained_filename;

You can see caffe failed to open your model file.

[ymotola]

I checked again, and the file does exists.
I also downloaded everything again but the same error persists.
What can be the cause it couldn't open this file?
