# voxl-tflite-server abort Source: https://forum.modalai.com/topic/1131/voxl-tflite-server-abort Category: General Questions (https://forum.modalai.com/category/2/general-questions) Posted: 2022-07-18 21:42:06 UTC by Isabella Yu Replies: 10 · Views: 2293 ## Isabella Yu · 2022-07-18 21:42:06 UTC I'm trying to run `voxl-tflite-server` on an m500, but when I run the command, this is the output: ``` ================================================================= skip_n_frames: 5 ================================================================= ================================================================= model: /usr/bin/dnn/ssdlite_mobilenet_v2_coco.tflite ================================================================= ================================================================= input_pipe: /run/mpa/hires/ ================================================================= ------VOXL TFLite Server------ Aborted ``` I tried running `voxl-configure-tflite` again, but same result. My configuration file from `/etc/modalai/voxl-tflite-server.conf` looks like this: ``` /** * This file contains configuration that's specific to voxl-tflite-server. * * skip_n_frames - how many frames to skip between processed frames. For 30hz * input frame rate, we recommend skipping 5 frame resulting * in 5hz model output. * model - which model to use. Currently support mobilenet for * object detection or midas for monocular depth * input_pipe - which camera to use (tracking or hires). */ { "skip_n_frames": 5, "model": "/usr/bin/dnn/ssdlite_mobilenet_v2_coco.tflite", "input_pipe": "/run/mpa/hires/" ``` ## Reply by Guest · 2022-07-18 21:54:35 UTC Hi @Isabella-Yu, Could please share the output of running ```voxl-version``` and ```voxl-inspect-services -v```? It would also be good to know if the voxl-tflite-server code has been modified in any way. ## Reply by Isabella Yu · 2022-07-18 21:58:54 UTC (in reply to Guest) @Matt-Turi Here's the output of `voxl-version` ``` cat: /etc/modalai/voxl-software-bundle-version.txt: No such file or directory -------------------------------------------------------------------------------- system-image: ModalAI 3.3.0 BUILDER: ekatzfey BUILD_TIME: 2021-06-06_19:28 kernel: #1 SMP PREEMPT Sun Jun 6 19:41:01 UTC 2021 3.18.71-perf factory-bundle: 1.0.1 (Yocto installation) -------------------------------------------------------------------------------- architecture: aarch64 processor: apq8096 os: GNU/Linux -------------------------------------------------------------------------------- voxl-suite: Package: voxl-suite Version: 0.5.0 Depends: libjpeg_turbo (>= 9.0.4), libmodal_exposure (>= 0.0.2), libmodal_json (>= 0.3.6), libmodal_pipe (>= 2.1.1), librc_math (>= 1.1.5), libvoxl_cutils (>= 0.0.2), libvoxl_io (>= 0.5.4), mavlink-camera-manager (>= 0.0.2), mongoose (>= 7.3.0), opencv (>= 4.5.2-2), openmp (>= 10.0.2), voxl-camera-calibration (>= 0.1.1), voxl-camera-server (>= 0.8.1), voxl-cpu-monitor (>= 0.2.0), voxl-dfs-server (>= 0.2.2), voxl-docker-support (>= 1.1.3), voxl-gphoto2 (>= 0.0.5), voxl-imu-server (>= 0.9.1), voxl-mavlink (>= 0.0.2), voxl-modem (>= 0.12.0), voxl-mpa-tools (>= 0.3.6), voxl-nodes (>= 0.2.0), voxl-portal (>= 0.1.2), voxl-qvio-server (>= 0.3.4), voxl-streamer (>= 0.2.6), voxl-tag-detector (>= 0.0.2), voxl-tflite (>= 2.2.3), voxl-tflite-server (>= 0.1.5), voxl-utils (>= 0.8.4), voxl-vision-px4 (>= 0.9.5), voxl-vpn (>= 0.0.3) Status: install user installed Architecture: all Installed-Time: 2166 ``` Here's the output of `voxl-inspect-services -v" ``` Service Name | Version | Enabled | Running | CPU Usage ---------------------------------------------------------------------------- docker-autorun | 1.1.3 | Enabled | Not Running | Not Running docker-daemon | 1.1.3 | Enabled | Running | 1.0 modallink-relink | 0.12.0 | Disabled | Not Running | Not Running voxl-camera-server | 0.8.1 | Enabled | Running | 7.1 voxl-cpu-monitor | 0.2.0 | Enabled | Running | 0.0 voxl-dfs-server | 0.2.2 | Enabled | Running | 8.0 voxl-drogon-detector | 0.3.4 | Disabled | Not Running | Not Running voxl-imu-server | 0.9.1 | Enabled | Running | 4.4 voxl-modem | 0.12.0 | Disabled | Not Running | Not Running voxl-portal | 0.1.2 | Enabled | Not Running | Not Running voxl-qvio-server | 0.3.4 | Enabled | Running | 0.0 voxl-streamer | 0.2.6 | Disabled | Not Running | Not Running voxl-tag-detector | 0.0.2 | Enabled | Not Running | Not Running voxl-tflite-server | 0.8.5 | Enabled | Not Running | Not Running voxl-time-sync | 0.9.5 | Disabled | Not Running | Not Running voxl-vision-px4 | 0.8.5 | Enabled | Running | 4.0 voxl-wait-for-fs | | Enabled | Completed | Completed ``` ## Reply by Guest · 2022-07-18 22:04:04 UTC It looks like you have a custom version of voxl-tflite-server running - voxl-inspect-services shows v0.8.5 and we are currently at v0.2.7. Is this correct? ## Reply by Isabella Yu · 2022-07-18 22:07:22 UTC (in reply to Guest) @Matt-Turi I actually don't have a custom version running, so I don't know how that happened. I'll reinstall voxl-tflite-server from the voxl packages page and see if that fixes things ## Reply by Guest · 2022-07-18 22:12:26 UTC Please let me know if that resolves the issue! ## Reply by Isabella Yu · 2022-07-18 22:21:59 UTC (in reply to Guest) @Matt-Turi I downloaded voxl-tflite-server_0.1.8.ipk from http://voxl-packages.modalai.com/stable/, pushed it to the drone via adb, and ran `opkg install voxl-tflite-server_0.1.8.ipk`. However, it seems that 0.1.8 is already installed: ``` * opkg_prepare_file_for_install: Refusing to load file 'voxl-tflite-server_0.1.8.ipk' as it matches the installed version of voxl-tflite-server (0.1.8). ``` I tried installing version 0.2.0 from dev instead, but it requires upgrading libmodal_pipe, libmodal_json, and voxl-opencv and I don't really want to do an upgrade right now in fear of breaking things :( ## Reply by Guest · 2022-07-18 22:53:23 UTC To force a fresh installation when it is the same version you have loaded, you can give opkg the flag: ```--force-reinstall``` to reinstall without needing to upgrade. The full command then would be: ```opkg install voxl-tflite-server_0.1.8.ipk --force-reinstall``` ## Reply by Isabella Yu · 2022-07-18 23:01:41 UTC (in reply to Guest) @Matt-Turi that did reinstall voxl-tflite-server 0.1.8, but still having the abort issue. `voxl-version` gives the same output, and `voxl-inspect-services -v` says the version of voxl-tflite-server is 0.1.8 as expected ## Reply by Guest · 2022-07-19 16:46:37 UTC @Isabella-Yu, I flashed a VOXL with the 3.3.0 system image and installed voxl-tflite-server v0.1.8 but was unable to recreate the abort issue you are seeing. voxl-tflite-server is a very power-hungry application, and I have seen issues like this arise from a bad apm/power connection to the drone. If this is not the cause, it may be worth attempting to reflash your system after backing up any important files. The latest stable release for voxl is [VOXL Platform 3.8.0-0.7](https://developer.modalai.com/asset/1). ## Reply by Isabella Yu · 2022-07-19 20:56:06 UTC (in reply to Guest) @Matt-Turi Yep, turns out switching to wall power fixed it. My battery power was too low. Thanks!
