Upgrade Tensorflow Version tflite-server
-
Let me try to address these individually!
- The "error" complaining
CUSTOM TFLite_Detection_PostProcess: Operation is not supported.is simply due to the very last operation of the model not being supported for gpu delegation. This is because it is not a standard op, so it just gets delegated to the cpu with no issues!
-
The issue with tflite-server hanging is not due to an improper install. I was able to replicate this on my setup using a BAD apm, but swapping out with a new one seemed to alleviate this issue. voxl-tflite-server is a fairly power hungry application, so I recommend checking for fraying cables and things of that nature but if you can send a picture of your current setup with cables/batteries etc included that may help debug. In the meantime, if you have another apm or power supply to quickly swap to and test please give that a try.
-
I personally have not had much luck with the resnet architectures, but I would double check data types and output tensor lengths, because those confidence values seem way off.
-
One last note, the dev release does not directly support all image formats out of voxl-uvc-server, only IMAGE_FORMAT_NV12 as of now. So, if your camera input is coming in as either IMAGE_FORMAT_YUV422 or IMAGE_FORMAT_YUV422_UYVY you may need to add some extra handling for that.
-
@Matt-Turi thank you for the fast reply again. I will check the apm and Camera server output format tomorrow and also send you a picture of the setup.
-
@Matt-Turi I got it working with changing the apm. Thank you for the suggestion. So i looked up my Camera Supports and it should support nv12 and in voxl-uvc-server it shows the following:
uvc_get_stream_ctrl_format_size succeeded for format 2after looking at the voxl-uvc-server:
https://gitlab.com/voxl-public/modal-pipe-architecture/voxl-uvc-server/-/blob/dev/src/main.c
L: 307 There is a for loop looking for a format to choose and format 2 should be NV12 but for some reason when looking at the stream over voxl-portal i get green stripes in the ouput. Do you know what the problem could be?The Camera is a Boson 640 Black-White Thermal Camera.

@Philemon-Benner Can you post the output of
lsusb,voxl-uvc-server -s, andvoxl-uvc-server -d -m -r 640x512? -

It's also working fine with nv12 format without the green lines:ffplay /dev/video4 -pixel_format nv12Output:

The error messages seem to be related to voxl-tflite-server and not voxl-uvc-server. Can you use voxl-streamer to stream the output of voxl-uvc-server to VLC and see if there are still green lines? What are you currently using to stream the output of voxl-uvc-server?

@Philemon-Benner It looks like voxl-uvc-server is working fine. The error messages seem to be related to voxl-tflite-server and not voxl-uvc-server. Can you use voxl-streamer to stream the output of voxl-uvc-server to VLC and see if there are still green lines? What are you currently using to stream the output of voxl-uvc-server?
@Eric-Katzfey Yeah i will try that today. I'm currently showing the stream with voxl Portal but with the voxl-tflite-server pipe. So voxl-uvc-server --> voxl-tflite-server --> voxl-portal(green lines output).

@Eric-Katzfey what a exactly do you mean with version mismatch, and where. The thing i could think of is tflite server 0.2.0 as seen above in the first try of installation i had some errors because of existing dependencies.

@Eric-Katzfey Ok so i tried using it with voxl-streamer. It's working completely fine. Any suggestions?

I also tried changing the model but still the same result.

Update:
So i stepped back to TF1 and trained the ssdlite_mobilenet_v2. It's working great on the drone with tflite-server 0.1.8. Thanks for all the suggestions ·@Matt-Turi . But i am looking forward to using the tflite-server 0.2.0. If you still have suggestions for fixing the green stripes in the new version please let me know, because for custom models the new tflite-version is way easier to integrate and the code is more understandable for me. -

We'll take a look.

@Matt-Turi is there a way to change small stuff in tflite-server code without building from source? Or is there a way to do it over ssh?. I can't access the usb slot from the voxl of the drone. I just wanna change the box color and confidence threshhold.
-
@Philemon-Benner If you make any changes to the code you will need to rebuild it from source. Once built, you can push this package over ssh either manually or using the deploy_to_voxl.sh script that is up on dev, which has an arg for ssh and send ip. Lines 106 and 107 of the script have the scp and opkg install commands that are used.

@Matt-Turi Thank you for the fast answer. Then i will build it from source.
But could be a cool feature in the future, if Box Color, Box Thickness and Confidence Threshhold would be in the config file. -
@Philemon-Benner great suggestion, I'll add that in soon. As for the green stripes issue seen with the dev version using a Flir Boson camera and voxl-uvc-server, I was able to successfully start and run tflite-server (mobilenetv2 w/gpu) with the same setup and only saw a few green "flickers" every few seconds due to the high input rate (60 fps) of the boson camera. I will work on some handling for this case, but have you tried your latest ssdlite_mobilenet_v2 model with the dev version of voxl-tflite-server (0.2.0)?

@Matt-Turi No i think because if you just update with opkg just the package is updatet and not the folders like the ones in /usr/bin/dnn where the models are stored. But yeah i will have a look at it. And also is the flickering happening on the in- or output? Because if it's happening in the input the inference results obviously will be less accurate, because of the green stripes.
