Can anyone recommend a Tflite Colab Notebook for VOXL2 Training
-
@tom i did all that and still stuck. could it be whats in the warning about being stuck in fastboot?
it is the voxl2 and not the voxl2 mini.[WARNING] This system image flash is intended only for the following
platform: VOXL2 (m0054)Make sure that the device that will be flashed is correct. Flashing a device with an incorrect system image will lead the device to be stuck in fastboot. -
@sansoy As long as you are using the voxl2 SDK and are indeed flashing voxl2 hardware then that warning can be ignored.
@tom hey Tom, i'm having absolutely no luck.
i've tried 3 times and it still just hangs atWould you like to continue with the VOXL2 (m0054) system image flash?
- Yes
- No
#? 1
I then followed the unbrick instructions and reinstalled everything per
https://docs.modalai.com/voxl2-unbricking/#ubuntu-hostGot the system back up and running and tried to install the latest SDK again with no luck.
It just hangs. -

It just hangs.UPDATE: Got it working with "sudo" for the install. normally one would get a permission errors and thought maybe that was the issue and sure enough. recommend updating your docs to
say sudo ./install.sh -

Here's a link to the tflites, and saved_models with inference results on never before seen images.
Any insight on how to make these models work in your environment would be awesomely appreciated.https://drive.google.com/drive/folders/1N1pU0jMRTb3rODSfIuETPrBf66m4ody7?usp=drive_link

@sansoy Interesting, sudo isn't normally required. I'm curious, what linux distro are you running?
-
@sansoy Huh, okay, that's what I run as well.
What groups are your default user in? For example, here is mine:
~ groups ok | 10:20:36 AM tom adm dialout cdrom sudo dip plugdev lpadmin lxd sambashare docker -
@sansoy Can you try adding your user to the dialout group and seeing if that fixes the issue?
sudo usermod -a -G dialout $USER -
When I get some time today I'll try to download your .tflite models and see what's going on. The good news is that the server is at least running! It very well may just be an issue with how the tensor is being parsed.

thomas.patton@modalai.comHey, they just gave me access to the Google Drive folder. Can you confirm that the
edgetpu.tflitein the root directory is the file you want me to try and get working?Thomas

@thomas i just checked permissions and you have access to all the files and yes to
edgetpu.tflit
ssd-mobilenet-v2-fpnlite-640_quant.tflite
ssd-mobilenet-v2-fpnlite-640.tflite

edgetpu.tflitemodel to load so I need a little bit more information on how each of these files was generated.Thomas

@thomas here's a yolov5 trained model.
https://drive.google.com/file/d/1wRbIXdylgx-EOGDLnuWnsytGd2DcTNeY/view?usp=drive_linkI used this instruction set to train a yolov5 model which works well on my mac, rPI4, linux box and nvidia jetson.

https://colab.research.google.com/drive/1QdgpSl63OSQdLTnFwOyP8dxLQ7W0HtmW?usp=sharingI found the bug in our code that's causing the issue. You can see on this line that a for YOLO models a former employee hardcoded the number of classes to be 80 leading to a segfault when we only have a single class like in your case. Here's what your model looks like on our server with the fix:
What I'm going to do is write a patch for
voxl-tflite-serverthat more intelligently reads the number from the labels file. This will be available in our SDK Nightlies and so you'll be able to use the fix tomorrow morning. If you'd like the fix sooner, what I can do is package the new voxl-tflite-server into a .deb so you can deploy it manually to your VOXL. I can help you out with this process if you're not familiar.Thanks,
