I run ./install_NEO_OCL_driver.sh successfully
But clinfo shows
clinfo
Number of platforms 0
Then I tried to uninstall all the dependencies that the Intel® Graphics Compute Runtime for OpenCL™ driver components required to use the GPU plugin
And tried to ./install_NEO_OCL_driver.sh successfully again
But still can not list the GPU platform
what is the problem?
Note that i run the demo successfully with GPU in Win10

Hello DongzhiZ,
On Linux the NEO RT requires the user have video group access. Can you try usermod -a -G? This instruction is listed at the bottom of he NEO deployment page.

It's also possible that for some reason your ICD references aren't visible... check /etc/OpenCL/vendors to ensure references are being placed appropriately.
It's possible libOpenCL.so can be influenced by environment variables to change the default directory from which to look for implementations. See the reference at the bottom of the readme here: https://github.com/KhronosGroup/OpenCL-ICD-Loader

I wrote an article describing how OpenCL works on Linux and how to troubleshoot installation issues. I suspect it will be helpful to debug this issue:
https://github.com/bashbaug/OpenCLPapers/blob/master/OpenCLOnLinux.asciidoc
Let me know if it helps, or if you have any suggestions for improvement. Thanks!

Hi Ben Ashbaugh:
Many thanks for offering your article, it helps me a lot to understand how OpenCL works on Linux. following your way of tracing, i got these lines when run my application:
strace ~/inference_engine_samples_build/intel64/Release/classification_sample_async -i /opt/intel/openvino/deployment_tools/demo/car.png -m ~/openvino_models/ir/FP16/classification/squeezenet/1.1/caffe -d GPU
open("/usr/local/lib/libOpenCL.so.1", O_RDONLY|O_CLOEXEC) = 3
open("/etc/OpenCL/vendors/intel.icd", O_RDONLY) = 4
read(4, "/usr/local/lib/libigdrcl.so\n", 28) = 28
open("/usr/local/lib/libigdrcl.so", O_RDONLY|O_CLOEXEC) = 5
write(2, "Failed to create plugin /opt/int"..., 219Failed to create plugin /opt/intel/openvino_2019.2.275/deployment_tools/inference_engine/lib/intel64/libclDNNPlugin.so for device GPU
Please, check your environment
failed to create engine: clGetPlatformIDs error -1001
) = 219
then, my application was able to find the ICD loader and the ICD loader was able to enumerate and load your vendor implementation.
Note that I run ubuntu16.04 on VMware
lspci command can only get VMware VGA and no GPU is found:

Does it mean that we can't see GPU in VMware?
Thanks!

Hi DongzhiZ,
It looks like the issue is related to Intel® Graphics Technology hardware visibility through the virtualization stack.
Some VMware users forwarded us to this article on VMware's website. The article covers passing through PCI devices. It may be relevant for your case.
Communicating in a VMWare product related forum may yield more specific information that may apply to your configuration.
For reference:
Per Intel® Graphics Compute Runtime for OpenCL™ instructions… a native installation on Ubuntu* OS needs access to /dev/dri/* . It gets access by adding the current user to the ‘video’ group…
Given lspci configuration you reported this represents a gap in how the iGFX device is exposed… Here is corresponding detail from my Ubuntu* OS 18.04 iGFX system:
