Remove bytetracker dependency from requirements.txt of /runtime/python/detection_with_tracker/

[sebastianfis]

The bytetracker package includes dependencies on very old versions of torch and lap packages. That raises compatibility issues with python versions >= 3.11 (it's not impossible getting it to run, but it's not easy and certanily not straightforward). The way I see it, the code does not make use of the bytetracker package (anymore?), but instead uses the byte track implementation of supervision. I suggets to remove this dependency to make installation on newer python versions easier.

Hi @sebastianfis,

Supervision requires bytracker, so it would still be a dependency.
But we plan on upgrading the supervision/bytetracker version in the near future.

Hi @hailocs,

Are you sure this is true for version 0.19.0? I checked the pyproject.toml of this release:
https://github.com/roboflow/supervision/blob/55f93a85b6a76c710c764f4f96dfb4d8cc73bb90/pyproject.toml
I could not find bytetracker in the packages section. I also did an experiment on my Raspi 5 with a freshly setup venv:
Installation with unchanged requirements.txt results in (due to incomapatibility of bytetracker with python 3.11 on bullseye:

For everyone who is also trying to run this on a RPi 5 and is stuck at the same point:

1. You have to download and install hailort v 4.18 FIRST:

pip install ~/Downloads/hailort-4.18.0-cp311-cp311-linux_aarch64.whl

2. Then remove bytetracker from the 1st line of requirements.txt (e.g. using nano). And install requirements via pip:

pip install -r requirements.txt 

This will result in a compatibility issue, as hailort==4.18 requires numpy==1.23.3, but requirements.txt does not define a certain numpy version, so the packages that require it will install the newest one:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
hailort 4.18.0 requires numpy==1.23.3, but you have numpy 2.1.3 which is incompatible.

3. The min. Version of numpy for all other pacakges except hailort is numpy==1.23.5. Luckily the detection with tracker example also works with numpy==1.23.5, so you can just fix it with

pip install numpy==1.23.5

Alternatively, you can just add a line numpy==1.23.5 to requirements.txt in step 2 to force this version already during requirements installation.

Afterwards the example runs smoothly on my RPi5. Note that the HEF file included in the example might not work. I recommend using either yolov8m.hef or yolov10b.hef from the Hailo model zoo and run by using:

python detection_with_tracker.py -i input_video.mp4 -o output_video.mp4 -l coco.txt -s 0.5 -n ~/Downloads/yolov10b.hef

Happy coding!
