Need help simulating .tflite yolo models on my linux machine.

@thomas
Hey thomas,
So I have followed your steps and loaded the log0009 data and then ran voxl-replay command while running voxl-tflite-server correctly configured with tracking option. But nothing happens after that it seems.
So the output I'm expecting at the end is to be able to have something like
Model Task Avg Cpu Inference(ms) Avg Gpu Inference(ms) Avg NNAPI Inference(ms) Max Frames Per Second(fps) Input Dimensions Source
custom-tflite-model Object Detection 33.89ms 24.68ms 34.42ms 34.86750349 [1,300,300,3]Where can I get such output after running the voxl-replay command. I think I'm missing some steps after that.
Please let me know what I'm missing here.
ThanksYeah, so my default all of our services don't print anything out when run. Do
voxl-tflite-server -tfor timing printouts.This won't give you a super organized printout like what you are writing. But it will give you out data on the per-iteration callback times and the breakdown per function. You'll then need to modify
/etc/modalai/voxl-tflite-server.confin different ways to get different timing printouts in order to build up a table of benchmarks.Thomas

Okay, So i did run voxl-tflite-server -t alongside voxl-replay command but am still not getting anything.
For yolov5 I get no output after running voxl replay. it just outputs this:
For my custom yolov7 nd yolov8 I get these errors:
I even referred to this thread https://forum.modalai.com/topic/2997/can-anyone-recommend-a-tflite-colab-notebook-for-voxl2-training/3
and configured the main.cpp file by adding if else statement for custom model to use YOLO model instead of OBJECT_DETECTION as the default one before even running the above commands.
I'm not sure why am I still not getting any output.

Sadly I won't have time to look at this today and am out of office tomorrow so I can't fully debug this for you. Let's focus just on YOLOv5 right now since that's the one we have onboard by default and it isn't segfaulting. Make sure you're launching tflite-server in a terminal and then in a separate terminal running the voxl-replay command.
I apologize for this, sorry I didn't have time for it today.

No worries. Ok, but even for yolov5 I've been running both voxl replay and tflite server commands in separate windows/terminals but still facing the issue.Let me know why is it so and how can we resolve this.

Okay so I've identified a problem in our timing code and am working on a fix. Here's a short-term solution for you:
- Make sure
/etc/modalai/voxl-tflite-server.confhas"input_pipe"set to"/run/mpa/tracking" - Get your VOXL's IP address with
voxl-my-ipand enter this IP into your web browser to pull up voxl-portal in your browser. - Run
voxl-tflite-serveron VOXL - Run your voxl-logger log as
voxl-logger -p /data/voxl-logger/log0009/or whatever the path is saved as
Now in your web browser, from the "Cameras" dropdown click tflite. You may need to refresh the page to get this to pop up. The permalink to this page is
<YOUR IP>/video.html?cam=tflite(e.g.http://192.168.0.198/video.html?cam=tflite) so you can optionally just go there. This overlay shows the ML model running and in the upper left of the frame shows a framerate. You can use this to estimate for the time being.Am working on the fix now, will let you know when it's released.

Okay, I've pushed up a change for our nightly builds to fix the timing printouts with the
-toption. So starting tomorrow you can flash the latest nightly SDK build and have this fix. If you'd like it today let me know and I can push the .deb up to Google Drive so you can flash it directly. Here is the link for the nightly SDK builds.Thomas

Hi,
Thanks for this info. So I have tried accessing the portal by running the voxl-my-ip command but found nothing getting printed out when I run that command. I inspected to make sure my voxl-portal service is running perfectly but still cant seem to get the ip for portal.
Also, can you push the latest SDK as well or share the deb with me.

Make sure you set up WiFi on VOXL! Here's the guide: https://docs.modalai.com/voxl-2-wifi-setup/

Hi thomas,
Could you please provide us the latest nightly sdk build for VOXL2 mini if you think we can work with that for now?Regards,

Hi thomas,
Is this package for voxl2min or voxl2?

Because I think this SDK is meant for M-0054 while our version is M0104. Let me know if we can go ahead and flash this SDK or not?
Thanks -
@thomas
Also, Now that I have flashed the SDK onto my chip its showing voxl2 in the shell screen instead of voxl2-mini. And even if I try and go ahead and do the following steps. I still cant get the desired output.

Have you also tried using this method? Or were there issues getting WiFi setup?

Yeah I'm really not sure what's going on here, on that nightly SDK
voxl-tflite-server -tis printing out timing information. I don't have a VOXL2 Mini to test on so if it's a specific issue there I'm really not sure. Let me try some stuff today and I'll get back to you.Thomas

Hi thomas,
Yes so right now we tried figuring out if maybe the issue is with the model not being specific to voxl2mini or maybe the logs are generated based on voxl2. But I dont think thats the case.
The thing which I'm concerned about is:- How do we identify or pinpoint the problem ...like are we supposed to see the output after the 'Disconnected from camera server' line or before? And if we are supposed to see it and are not able to... then where exactly is the problem happening in the src/main.cpp file of voxl-tflite-server. Can we debug that somehow?
- Also did you check running the voxl-replay logger command directly without having any camera setup or camera-server configured.... similar to the way we are currently running on our end.

If
voxl-tflite-serverwas running into an actual error you'd see some sort of an error message printout. We typically debug issues throughvoxl-portalbut if you aren't able to get WiFi set up you won't be able to do so. I again reflashed a nightly SDK to confirm things are working on my end and they are. To reconfirm:- Flash the latest SDK nightly from the link shared above
- Modify
/etc/modalai/voxl-tflite-server.confto have/run/mpa/trackingas its input. This file gets overwritten on flash so make sure you do this. voxl-tflite-server -tin one terminalvoxl-replay -p /data/voxl-logger/log0009/in another
I can tell you that replay doesn't care about camera server being configured, it should work regardless.
