inference on a frame obtained from the memory space

Hi again @Spanner ! 😊I need to infer an image obtained from byte data stored in a memory space (https://docs.python.org/3/library/mmap.html) and after converting the bytes I get an image.I've seen the sources available for create_inference_stream and I know that I can make inferences to images (https://github.com/axelera-ai-hub/voyager-sdk/blob/release/v1.2.5/docs/tutorials/application.md), but I have to specify the/path/to/file. But in this case I won't have that information.In the code I'll have this line where I read the bytes in the memory space: frame_size=image_width*image_height*3 //RGB frame_bytes = mm.read(frame_size)And then I get the new image: frame = np.frombuffer(frame_bytes,dtype=np.uint8).reshape((image_height,image_width, 3))Is there any way to infer “frame”?Thank you!

Yolo Performance Issues

Hello, I try to use a YOLO model on 8 camera streams in parallel on the Metis PCIe card. 20-30 fps per camera stream is all I need. With the 548 fps end-to-end stated for YOLOv8s in https://axelera.ai/metis-aipu-benchmarks, it should be possible to reach ~68 fps per camera. As a small test I wrote a python script, which creates a inference stream with 8 videos as input:from axelera.app import config, display, inf_tracersfrom axelera.app.stream import create_inference_streamdef run(window, stream): for frame_result in stream: window.show(frame_result.image, frame_result.meta, frame_result.stream_id) fps = stream.get_all_metrics()['end_to_end_fps'] print(fps.value)def main(): tracers = inf_tracers.create_tracers('core_temp', 'end_to_end_fps', 'cpu_usage') stream = create_inference_stream( network="yolov5s-v7-coco", sources=[ str(config.env.framework / "media/traffic1_1080p.mp4"), str(config.env.framework / "media/traffic1_

Raspberry Pi 5 - Metis inference with GStreamer Pipeline

Hi, I'm working on an RPI5 and I have the voyager SDK inside a container with ubuntu 22 and it works. I wanted to try running an inference on a stream using GStreamer. First, I tried to access the stream and I managed with the following command:GST_PLUGIN_PATH=/voyager-sdk/operators/lib AXELERA_DEVICE_DIR=../opt/axelera/device-1.2.5-1/omega LD_LIBRARY_PATH=/voyager-sdk/operators/lib:/opt/axelera/runtime-1.2.5-1/lib:$LD_LIBRARY_PATH gst-launch-1.0 rtspsrc location='rtsp://…..' latency=200 ! rtph264depay ! avdec_h264 ! videoconvert ! autovideosink Now I wanted to try the axinferencenet plugin but I'm having problems. I've tested various commands and formats, such as: GST_PLUGIN_PATH=/voyager-sdk/operators/lib AXELERA_DEVICE_DIR=../opt/axelera/device-1.2.5-1/omega LD_LIBRARY_PATH=/voyager-sdk/operators/lib:/opt/axelera/runtime-1.2.5-1/lib:$LD_LIBRARY_PATH gst-launch-1.0 rtspsrc location='rtsp://...' latency=200 ! rtph264depay ! avdec_h264 ! videoconvert ! video/x-raw,format=BGRA ! axtran

Is graphical video output expected to work from within the docker SDK?

Hi all,I’m a docker noob, so please bear with me if this is a stupid question.To get the SDK operational on my Ubuntu-24.04 system I followed the Install Voyager SDK in a Docker Container and can make it up to test-running some inferences. Alas, while I expected the videos to be displayed in a dedicated window at full resolution, for me they are shown in the active text-console (ncurses-based I assume), obviously coarse and slow.I tried to learn how to activate graphics output from within docker, but all I got was that docker essentially is meant to be text-only and graphics usually is provided via web-browser of pages served from within docker.So to put it bluntly: those videos showing Voyager SDK performing object detection at exhibitions at full-resolution and full-framerate, are those from within docker or are they run from a native ubuntu-22 system?If it is possible to tune docker to have that video output, a mini-howto would help a lot.

Ubuntu 24.04 support, and Docker containers

Seems Ubuntu 24.04 is not supported at the moment. What are the plans for this version? Can you give some insight on what needs to be changed to get this installed on that version?

Issues Deploying and Running yolov5m6.onnx on M.2

I am encountering issues when trying to deploy and run the YOLOv5m6 ONNX model on the Metis M.2. Below are the details of the steps I followed and the issues that arose:1. Deployment Process:I used the following command to deploy the model:./deploy.py customers/mymodels/yolov5m6-object-detection.yamlThe deployment was successful, but I encountered warnings about memory overflow during the buffer fitting process:LowerTIR failed to fit buffers into memory after iteration 0/4. Pool usage: {L1: alloc:4,195,840B avail:4,194,304B over:1,536B util:100.04%, L2: alloc:6,864,384B avail:8,077,312B over:0B util:84.98%, DDR: alloc:54,275,328B avail:260,046,848B over:0B util:20.87%}2. Inference Process:I then attempted to run inference with the following command:./inference.py c-yolov5m6-object-detection chinmay/Vehicle-CV-ADAS/assets/VID-20250208-WA0008.mp4 --save-output ~/Desktop/voyager-sdk/chinmay/saved_videos/output.mp4The model failed to run due to a ShapeInferenceError related to incompatibl

Using Metis M.2 for matrix operations

Hi,I know Metis can be used for ML etc. but wondering whether it’s suitable to do some more low-level operations like big matrix multiplication, FFT of data stored in Metis memory etc. - more like on CUDA (some DSP/Math library)? I assume I could use torch basic math functions? Dominik

Anonymous

hey,I am an ARM enthusiast and I wanted to check if you have any compatibility list.Are you supporting NXP and MediaTek?What about the Broadcom CPU on latest Raspberry Pi?

Where can I request SDK feature support or roadmap info?

Is there a preferred way to suggest new features or request model support? Also wondering if there’s a public roadmap or at least a rough idea of what’s coming up in the next releases (especially around expanded model support or tools for deployment).Would be great to understand how other users here are submitting feedback — and whether the Axelera team actively tracks suggestions from this forum too. Cheers!
