Hi, I am facing an issue with the system identifying the Intel Arc GPU following the manual here: Experimental: Intel® Arc™ A-Series GPU Software Installation

Here is some spec of my system:

  • Hardware: Intel Arc A750
  • software environment: WSL2 with Ubuntu 22.04 LTS installed
  • GPU driver version: 31.0.101.4255 (Released March 16, 2023) at the Windows
  • host OS: Windows 11 Pro Education 22H2
  • Using a Miniconda virtual environment

The issue that I have been facing since now is the last step python -c "import intel_extension_for_tensorflow as itex; print(itex.__version__)"
which output

 python -c "import intel_extension_for_tensorflow as itex; print(itex.__version__)"

TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

More information: https://developers.google.com/protocol-buffers/docs/news/2022-05-06#python-updates

from the output, it seem that although I install the intel-extension for tensorflow , the output still requires CUDA driver.

By using the intel_extension_for_tensorflow/tools/env_check.sh in this github repo, I've passed all the tests provided, which means no problem detected over my system and dependency.

here might be some other useful information provided by my system:

Primary display adapter: #6

which looks like it didn't identify my GPU driver (it shows the vendor as Microsoft, instead of Intel as suggested? ).
I tried to find a solution to this but it didn't work out too well, all of the driver issues come with the cuda driver ):

@teogi do you use TensorFlow 2.12?
If you use ITEX 1.1 release, please use TensorFlow 2.11, we will release ITEX with TensorFlow 2.12 soon, or you can use latest master for TensorFlow 2.12 support.

BTW, do you install the driver inside Ubuntu? https://github.com/intel/intel-extension-for-tensorflow/blob/main/docs/install/experimental/install_for_arc_gpu.md#native-linux-running-directly-on-hardware

I do try on the native Ubuntu, but there is some problem with the version of Linux.
I didn't do it on WSL2, since the readme file didn't suggest to do that?

btw, the downgrade to the TensorFlow 2.11 did not solve the problem unfortunately.
It still requires something like libcudart.so.

@teogi

  1. TF always try to load libcudart.so. It's default behavior and not impact the ITEX.
    Please ignore it.

  2. The error in your case is libmkl_sycl.so.3: cannot open shared object file.
    a. Please install oneMKL as the guide in install_for_arc_gpu.md.
    like: sudo apt-get install intel-oneapi-runtime-dpcpp-cpp intel-oneapi-runtime-mkl.
    b. Please enable oneMKL before run ITEX:
    source /opt/intel/oneapi/setvars.sh.
    refer to https://github.com/intel/intel-extension-for-tensorflow/blob/main/docs/install/experimental/install_for_arc_gpu.md#setup-environment-variables

  3. If you still have any error, please run following cmd to check and share the log to us:
    (tf)$ bash /path to site-packages/intel_extension_for_tensorflow/tools/env_check.sh

The env_check.sh looks OK, the driver are installed.
'vainfo' shows the video "vaapi" interfaces, it's NOT OK. But tensorflow does not depends on vaapi. So it's another issue.

ITEX depends on sycl/opencl interfaces.
Could you check the output of clinfo?
What's your enviroment, the OS, tensorflow and ITEX version?

Thank you for the documentation. I've been facing the same issue as OP. Both, under WSL2 and native Ubuntu 22.04.

I hope the following info could help

@teogi from you log, that only import ITEX can find GPU
2023-04-05 23:29:03.283712: I itex/core/devices/gpu/itex_gpu_runtime.cc:129] Selected platform: Intel(R) Level-Zero
But your real workload cannot.
Suspect your environment has some lib conflict. Can you run your workload with:
OCL_ICD_ENABLE_TRACE=1 OCL_ICD_DEBUG=2
and share the log? thanks.

Sorry for the ignorance,

how can I set OCL_ICD_ENABLE_TRACE=1 OCL_ICD_DEBUG=2?

I notice that the problem happens when I use jupyter notebook or jupyter lab. If I run a python script from the command line using the same environment it shows the GPU

And if I use source /opt/intel/oneapi/setvars.sh and run the Quick example as a python script, works fine but if I run the same code in a jupyter notebook it throws:

If I don't enable the oneAPI componets through source /opt/intel/oneapi/setvars.sh and run the script, again it runs fine and shows the device but under a notebook shows: E itex/core/devices/gpu/itex_gpu_runtime.cc:173] Can not found any devices. To check runtime environment on your host, please run itex/itex/tools/env_check.sh.

I think the jupyter notebook should be set to correct kernel which is installed with ITEX.
In python cli, you run the script in correct python running envirionment.
but in jupyter notebook, you run the script in default kernel which is different running environment of python cli.

@NeoZhangJianyu Yes, you were right, I was using the default kernel.

I set the kernel from the environment with itex (tf) with python -m ipykernel install --user --name tf --display-name "TensorFlow"

The problem still persist. I checked the json file to see if the kernel is pointing to the right path anaconda3/envs/bin/tf/python in my case. Both, under WSL2 and Ubuntu. I tried VSCode too because it let me directly choose the kernel but id did not work.

  1. before run ITEX, we need to enable oneAPI by source /opt/intel/oneapi/setvars.sh.
    In jupyter notebook case, I suggest enable oneAPI before startup jupyter notebook service.

  2. Your error: NotFoundError: /opt/intel/oneapi/lib/intel64/libmkl_sycl.so.3: undefined symbol: viRngGeometric_64
    Looks like the version oneMKL (included in oneAPI base toolkit) is wrong.
    Could your run itex/itex/tools/env_check.sh and share the log?

Thank you!

@teogi The env_check.sh looks OK, the driver are installed. 'vainfo' shows the video "vaapi" interfaces, it's NOT OK. But tensorflow does not depends on vaapi. So it's another issue.

ITEX depends on sycl/opencl interfaces. Could you check the output of clinfo?

Sorry for the late reply, here is my clinfo output:

What's your enviroment, the OS, tensorflow and ITEX version?

Some information has provided since the beginning, to make it more clearly and thorough, I will requote it below with other information that asked for.

Here is some spec of my system:

  • Hardware: Intel Arc A750
  • software environment: WSL2 with Ubuntu 22.04 LTS installed
  • host OS: Windows 11 Pro Education 22H2
  • Using a Miniconda virtual environment (with python 3.9)

I have downgraded tensorflow from version 12 to 11 as advised; my ITEX version comes with 1.1.0, installed using pip.

btw, is there any way to turn off the Nvidia driver warnings when using ITEX?

@NeoZhangJianyu Yes, you were right, I was using the default kernel.

I set the kernel from the environment with itex (tf) with python -m ipykernel install --user --name tf --display-name "TensorFlow"

The problem still persist. I checked the json file to see if the kernel is pointing to the right path anaconda3/envs/bin/tf/python in my case. Both, under WSL2 and Ubuntu. I tried VSCode too because it let me directly choose the kernel but id did not work.

Best regards

@mikemayuare Please help to check the version of libstc++.so both in your conda env (eg path: ~/anaconda3/envs/${your conda env name}/lib/libstdc++.so.6) and in your system env (eg path: /usr/lib/x86_64-linux-gnu/libstdc++.so.6). If they are different, this should be a lib conflit issue between your conda running env and your sys env. In this case, you could upgrade the libstdcxx version in your conda env by conda install -c conda-forge libstdcxx-ng and then check whether Intel gpu devices can be detected via Jupyter notebook. Thanks.

If this does not help, could you please set the environment variables OCL_ICD_ENABLE_TRACE=1 OCL_ICD_DEBUG=2 that @guizili0 mentioned, and share the output of running the workload? (If you are in a jupyter nootbook, you can execute %env OCL_ICD_ENABLE_TRACE=1 and %env OCL_ICD_DEBUG=2 in a cell before your workload cell.)

Sorry for the delay.

@wangkl2 as you suspected, it was a library conflict issue.

Thanks to all for the great support.

@teogi Sorry repond delay.

From you clinof output, the device is OK, so the GPU driver and OCL driver are OK.

Number of devices 1
Device Name Intel(R) Graphics [0x56a1]
Device Vendor Intel(R) Corporation
Device Vendor ID 0x8086
Device Version OpenCL 3.0 NEO

While your example fail to get the device.

To enable them in other operations, rebuild TensorFlow with the appropriate compiler flags.

So it is likey some libray confiliction at APP/example level.
The problme looks similar to that mikemayuare ran into.
Please try @wangkl2 suggestions. I copied here:

  1. Please check the version of libstc++.so both in your conda env (eg path: ~/anaconda3/envs/${your conda env name}/lib/libstdc++.so.6) and in your system env (eg path: /usr/lib/x86_64-linux-gnu/libstdc++.so.6). If they are different, this should be a lib conflit issue between your conda running env and your sys env. In this case, you could upgrade the libstdcxx version in your conda env by conda install -c conda-forge libstdcxx-ng and then check whether Intel gpu devices can be detected via Jupyter notebook. Thanks.

  2. If this does not help, could you please set the environment variables OCL_ICD_ENABLE_TRACE=1 OCL_ICD_DEBUG=2 that @guizili0 mentioned, and share the output of running the workload? (If you are in a jupyter nootbook, you can execute %env OCL_ICD_ENABLE_TRACE=1 and %env OCL_ICD_DEBUG=2 in a cell before your workload cell.)

Thanks!

btw, is there any way to turn off the Nvidia driver warnings when using ITEX?
@teogi

We are sorry for this. Google Tensorflow output this as the default GPU is Nvidia GPU.
There is no setting to turn it off in ITEX.
I'll share you the recent info next week.

Thanks!

The conda libraries have the lib conflicts as you mentioned.
By locating all the libstdc++.so.6, I found that version sys env was libstdc++.so.6.30 but in my conda, there was libstdc++.so.6.29

The problem is the default version for anaconda is libstdcxx-ng.11.2.0, but the version installed through conda-forge channel will be 12.2.0.

Solved the lib conflict problem by rebuild the environment through conda create ... -c conda-forge , but the problem still exists.
The output after the configuration suggested:

also, there is some differences in the version of stdc++.so.6 between sys env, conda env, and also oneapi environment.

The version at oneapi's env 6.0.22 is lower than sys env 6.0.30. Should I following the version at oneapi's env and downgrade the libstdc++.so?

Hi @teogi ,

Sorry for the inconvenience.
There is a workaound for the lib conflicts, to preload the correct library manually.

  1. LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.30 python quick_example.py
    or export LD_PRELOAD
  2. export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.30:$LD_PRELOAD

If it helps, I installed python==3.10 and tensorflow==2.11.0. Its able to detect both dedicated (Arc 770) and integrated (UHD Graphics 770) GPU. But I am not able to load the model on the device.

@Ankur-singh, could you please try ZE_AFFINITY_MASK =1 python your_test.py ? This will mask the iGPU.

I close the issues , but please feel free to reopen if any updates.

FYI, there is new version for your future test: https://intel.github.io/intel-extension-for-tensorflow/latest/docs/install/experimental/install_for_arc_gpu.html
