Did you create a log folder in Caffe directory? It should be on the same level like folders data and examples.

I have created a log folder in Caffe directory.but there also is a erro

[tseckin]

Also I have similar problems building. I successfully run cmake and make commands. Apparently I have Radeon 7850 but make runtest command gives me

Cannot find any dGPU!

It seems that you have a really old GPU with OpenCL 1.1.
I suspect the error is caused by the incompatibility
Thanks

Oh the log said that null platform pointer. Opencl caffe did not find your platform. Suggest you go to arc/caffe/device.cpp, device::init() look at the logic, print out more info

      CL_QUEUE_PROFILING_ENABLE, NULL);
  if (NULL == CommandQueue || NULL == CommandQueue_helper) {
    fprintf(stderr, "Err: Failed to Create Commandqueue\n");
    return 0;
  }
  BuildProgram (oclKernelPath);
  row = clblasRowMajor;
  col = clblasColumnMajor;
  return 0;
}

Probably it's can't go into

for (i = 0; i < (int) uiNumDevices; i++) {
        clGetDeviceInfo(pDevices[i], CL_DEVICE_HOST_UNIFIED_MEMORY,
            sizeof(cl_bool), &unified_memory, NULL);
        if (!unified_memory) { //skip iGPU
          //we pick the first dGPU we found
          pDevices[0] = pDevices[i];
          device_id = i;
          LOG(INFO) << "Picked default device type : dGPU " << device_id;
          break;
        }

Because uiNumDevices == 0.
which goes from clGetDeviceIDs
But I have no idea how to deal with this.
BTW. I have ubuntu 16.04. and radeon HD 8750m. If that matter.

Or may be OCL_CHECK is failed for &uiNumDevices?

[gujunli]

you can insert a few printfs in this file to trace down whether the
GPU are detected correctly. EG. first print out the num of devices

clGetDeviceIDs(PlatformIDs[0], CL_DEVICE_TYPE_GPU, 0, NULL, &numDevices);

uiNumDevices = numDevices;

printf("#device %d \n", uiNumDevices);

if (0 == uiNumDevices) {

LOG(FATAL) << "Err: No GPU devices";

} else {
pDevices = (cl_device_id *) malloc(uiNumDevices * sizeof(cl_device_id));

@gujunli I've found problem. Variable unified_memory == 1. Because of this it can't get into

if (!unified_memory) { //skip iGPU
          //we pick the first dGPU we found
          pDevices[0] = pDevices[i];
          device_id = i;
          LOG(INFO) << "Picked default device type : dGPU " << device_id;
          break;

//skip iGPU What is that?

[gujunli]

I see. So your GPU is an integrated GPU. The opencl caffe by default is set to look for a discrete GPU. You can comment out the unifiedmemotmry logic, use what ever GPU it finds. See whether it works. Junli

I want to use caffe with my AMD discrete graphics.

Also i tried DRI_PRIME=1 make runtest. Have no effect.

[naibaf7]

Maybe try this, since the AMD branch is no longer actively maintained:
