System information

• Have I written custom code (as opposed to using a stock example script provided in TensorFlow): No

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04):14.04.3-->Trusty

• TensorFlow installed from (source or binary):Source

• TensorFlow version (use command below):1.0 (Steps-> Downloaded tensorflow from https://github.com/benoitsteiner/tensorflow-opencl, ./configure - to configure project)

• Bazel version (if compiling from source):0.4.5

• CUDA/cuDNN version:NA

• OPENCL Version:
  Number of platforms: 1
  Platform Profile: FULL_PROFILE
  Platform Version: OpenCL 2.0 AMD-APP (1800.11)
  Platform Name: AMD Accelerated Parallel Processing
  Platform Vendor: Advanced Micro Devices, Inc.
  Platform Extensions: cl_khr_icd cl_amd_event_callback cl_amd_offline_devices

• GPU model and memory:
  Platform Name: AMD Accelerated Parallel Processing
  Number of devices: 2
  Device Type: CL_DEVICE_TYPE_GPU
  Board name: AMD Radeon (TM) R5 M335
  Memory: 4096M

• Exact command to reproduce:
  run the python script -- ipython keras_code.py

• ** G++/GCC version**:
  g++-4.9 (Ubuntu 4.9.4-2ubuntu1~14.04.1) 4.9.4

I have compiled CPP programs, they work fine.

• ComputeCPP: 0.1.1

-- ** Python**: I am using Anaconda distribution Python for 2.7.2. (Anaconda - 2.4.3)

Describe the problem

I have compile tensorflow, and deployed the same -> No issues here. when I try to run the code I run into the following error:

2017-04-23 14:01:15.180795: W ./tensorflow/core/common_runtime/sycl/sycl_util.h:44] No OpenCL GPU found that is supported by ComputeCpp, trying OpenCL CPU
2017-04-23 14:01:15.180843: F ./tensorflow/core/common_runtime/sycl/sycl_util.h:53] No OpenCL GPU nor CPU found that is supported by ComputeCpp
Aborted (core dumped)

I have attached the code file. Please note this is a simplified version of the file. The logic is:

1. Read data from files,
2. Pass it through a NN
   I am using Keras as the Functional programming API on top of Tensorflow.

Please let me know if there are any fixes or if I can do something to get round this issue.

I dont think Compute cpp supports Hainan AMD GPU. Not sure if this is a tensorflow issues at all. If possible please advice how, of at all, can I proceed with this issue.

Further updates:
I upgraded ComputeCPP to 0.1.4 version.
But I still have the same error. Please advise.

Hello @rahasayantan,

It is indeed an issue with computecpp so you could probably have more help here: https://github.com/lukeiwanski/tensorflow

Just a quick question though did you install ocl-icd-opencl-dev opencl-headers?
Also the issue may come from your kernel version as this page advises to downgrade to 3.19: http://deep-beta.co.uk/setting-up-tensorflow-with-opencl-using-sycl/

[rahasayantan]

@Zakor I did install ocl-icd-opencl-dev opencl-headers.
I will see if I find any help on the sites you shared. Thanks for your help.

@rahasayantan : Could you share performance numbers in relation to pip-only tensorflow and optimized tensorflow? I am interested to see how much more performant tensorflow-opencl is with a beefier dGPU. Thank you ahead of time! For my iGPU, since all computation was shifted from CPU to the tiny iGPU, it turned out to be less performant. But there is hope for you :-)

@thornhale: Currently the Tensorflow on GPU I have is crashing because of Device unsupported error. Raised an issue on Tensorflow Git. They have asked me to wait till the latest merge is complete and then I need to recompile and retest. I will let you know my findings once I have GPU setup and working.

Updates: I downloaded the latest version from https://github.com/lukeiwanski/tensorflow-opencl. This one gives coredump. There are challenges installing from tensorflow's main git repo and there seems to be issues on compiling protobuf.

@rahasayantan do you have any updates on this?
