[Bug] 11th gen iGPU hangs on simple model #4969

Closed dmenig closed 3 years ago

dmenig commented 3 years ago
System information (version)
Detailed description

Openvino code hangs on this hardware using the iGPU, but it works with the CPU, on a very common model.

Steps to reproduce

First run this to export the onnx model.

import torch
import torchvision.models as models

dummy_input = torch.randn(1, 3, 224, 224)
model = models.resnet18()

with torch.no_grad();
    torch.onnx.export(
        model,
        dummy_input,
        "resnet.onnx",
        verbose=True,
    )

Then I enter the official container for openvino : docker run --name openvino -it --device /dev/dri:/dev/dri --device-cgroup-rule='c 189:* rmw' -v /dev/bus/usb:/dev/bus/usb --rm openvino/ubuntu20_dev:latest

Then I run the conversion script : 

cd /opt/intel/openvino_2021.2.185/deployment_tools/model_optimizer
python3 mo.py --input_model /home/openvino/resnet.onnx  --output_dir /home/openvino/ --data_type FP16

Then simply loading the model hangs : 

from openvino.inference_engine import IECore

model_bin = "resnet.bin"
# Loading the Inference Engine API
ie = IECore()
ie.available_devices
# Loading IR files
net = ie.read_network(model="resnet.xml", weights=model_bin)
# Loading the network to the inference engine
exec_net = ie.load_network(network=net, device_name="GPU")
** and it hangs here **

I verified that the same code works with CPU, or that it works with another iGPU (i3-7200U).

Although such a script still shows the GPU is available : 

>>> from openvino.inference_engine import IECore
>>> 
>>> # Loading the Inference Engine API
>>> ie = IECore()
>>> ie.available_devices
[E:] [BSL] found 0 ioexpander device
['CPU', 'GNA', 'GPU']

To give another use case, maybe easier to reproduce : When I run this

docker run -it -u 0 --device /dev/dri:/dev/dri --device-cgroup-rule='c 189:* rmw' -v /dev/bus/usb:/dev/bus/usb --rm openvino/ubuntu20_dev:latest 
/bin/bash -c "apt update && apt install sudo && deployment_tools/demo/demo_security_barrier_camera.sh -d GPU -sample-options -no_show"

It eventually hangs here :

dmenig commented 3 years ago

When it hangs, one cpu core is constantly at 100% and a process named "tracker-miner-fs" seems to be responsible.

zulkifli-halim commented 3 years ago

Your host system is Ubuntu 20, please follow the Configuration Guide for the Intel® Graphics Compute Runtime for OpenCL™ on Ubuntu* 20.04..

Intel® Graphics Compute Runtime for OpenCL™ driver components are required to use a GPU plugin and write custom layers for Intel® Integrated Graphics. The driver is installed in the OpenVINO™ Docker image but you need to activate it in the container for a non-root user if you have Ubuntu 20.04 on your host. To access GPU capabilities, you need to have correct permissions on the host and Docker container.

dmenig commented 3 years ago

Are you sure ? The code snippets I used do work on Ubuntu 20 for intel GPU coming with i3-7200U.

dmenig commented 3 years ago

Anyways I have tried the first method on the page you linked : 

docker run -it --rm --device /dev/dri --group-add=$(stat -c "%g" /dev/dri/render*) openvino/ubuntu20_dev:latest

It doesn't work : it prints this : 

groups: cannot find name for group ID 109
[setupvars.sh] OpenVINO environment initialized
openvino@1816ceaf7710:/opt/intel/openvino_2021.3.394$

And then same hanging problem on the scripts mentionned above.

dmenig commented 3 years ago

Using the second method at least works but doesn't solve the hanging problem.

Have you test the demo on OpenVINO with iGPU on regular OpenVINO installation or test it without using Docker?

I only tested with docker.

dmenig commented 3 years ago

I tried installing openvino myself after your message following these steps https://docs.openvinotoolkit.org/latest/openvino_docs_install_guides_installing_openvino_apt.html Then the "Steps for Intel® Processor Graphics (GPU)" in here https://docs.openvinotoolkit.org/latest/openvino_docs_install_guides_installing_openvino_linux.html

GPU is properly listed in available devices aftewards. But I still have the same hang problem.

dmenig commented 3 years ago

I also tried building from source with this cmake command 

cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_MKL_DNN=OFF -DENABLE_CLDNN=ON   -DENABLE_NGRAPH=ON \
  -DENABLE_OPENCV=OFF  -DENABLE_PYTHON=ON -DPYTHON_EXECUTABLE=/usr/bin/python3 \
  -DPYTHON_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.8.so -DPYTHON_INCLUDE_DIR=/usr/include/python3.8  ..

It succeeds and shows GPU in available devices in python, but still the same hanging problem.

Hi @hyperfraise

Which GPU driver version are you on? You can check using clinfo.

Using your provided instructions, I was able to generate the onnx model, convert to IR and run on GPU device (9th gen). It may be specific to 11th gen, could you try to install this version 20.41.18123 and see if it works?

Regards, Jesus

        Programs using 3.0 features may crash
        or behave unexpectedly

I conclude that I updated the driver successfully. This solves the hanging problem as well (although I'm noting that the loading of the model in iGPU memory is very slow : ~2m30s).

If I may say, I believe that this incompatibility should be listed somewhere ? Or at least there should be some indication anywhere on Openvino's docs that this driver should be the most recent one, idk.

Thank you very much !

@hyperfraise

This solves the hanging problem as well (although I'm noting that the loading of the model in iGPU memory is very slow : ~2m30s).

Was the loading time similar on the previous driver? Take a look at this support article on how to load model from cache.

Regards, Jesus

dmenig commented 3 years ago

As noted above, there couldn'tbe any loading on the previous driver : just hanging.

jgespino commented 3 years ago

@hyperfraise oh yes.... my mistake. Loading on GPU will take a bit longer as the kernel compiles, the article mentioned in my previous response should help when reloading the model after the first time.
