Hi @matheusfalcaopinto ,
What model are you running on GpuAcc that segfaults?
@ArmRyan I tired the mock_model.tflite, conv2d.tflite, fp32_model.tflite, tried some mobilenet and efficientdet from TF Hub and the mobilenet model from the pyarmm video file example. I think the number of warnings that I get is relatated to the size of the model somehow.
Hi, The warnings get called on any layer that uses the deprecated functions, so the more layers that use the function, the more warnings. I will try to run this locally and see if I come across a similar issue.
Hi,@matheusfalcaopinto, warning show CL Backend use a deprecated interface, but maybe not lead to Segmentation fault. Can check which opencl version on your devices? Mali-T860 GPU has deponded on opencl . Hi @ArmRyan, can your known which releationship between Mali GPU version and OPENCL version?
@Shelton-N Hi! I'm using the last package provided by Debian Bullseye, sorry but I can't verify right now, I think was something like libopencl.
Hi @matheusfalcaopinto. I just want to check in on the status of this issue. Is this still a problem for you? I notice that in your original post, you have edited to say that the FP32 model does not produce a segmentation fault and works. Can this ticket be closed because of this or would you like further assistance with another model?
@keidav01 hi! I'm facing the same issue still, but for now I can't work on it for a couple days unfortunately . If needed you can close the post.
@matheusfalcaopinto no problem at all. I will keep it open for now. Please feedback when you can and we will try to assist

Hi! I manage to build armnn with the build-tools scripts (without docker):
./install-packages.sh
./setup-armnn.sh --target-arch=aarch64 --all
./build-armnn.sh --target-arch=aarch64 --all --neon-backend --cl-backend --armnn-cmake-args='-DFLATC=/root/armnn/build-tool/scripts/build/flatbuffers/flatc
An then follow the DelagateQuickStartGuide steps:
sudo apt-get install python3-pip
sudo pip3 install virtualenv
cd your/tutorial/dir
virtualenv -p python3 myenv
source myenv/bin/activate
pip3 install --extra-index-url https://google-coral.github.io/py-repo/ tflite_runtime==2.5.0.post1
But when I run the python example in the Delegate Guide using GpuAcc I get:
Info: ArmNN v30.0.0
arm_release_ver of this libmali is 'r18p0-01rel0', rk_so_ver is '4'.Info: Initialization time: 3.12 ms.

Segmentation fault
When I run the same code but with CpuAcc I get the same warnings but without the segmentation fault part (actually I get the output_tensor data normally).
Any ideas of what is happening here? Thanks!
PS: The machine is an aarch64 Debian Bullseye (RK3399 with Mali-T860 GPU).
