No matching distribution found for dash==2.9.3 (from -r requirements.txt (line 1))

Is this due to the fact that alfred comes with debian stretch running python 3.5 and isn't updateable...

Greets,

Maybe it's just enough to upgrade pip:
pip3 install --upgrade pip

OK it's not - i checked the requirements and at least dash requires python 3.6. So i'm going to use a seperate linux machine for cassandra.

Is there any reason not to copy the dash fix min.js in the dockerfile?

Dash fix have to be copied in any case. If you don't do that the remote control won't be work properly

Python 3.6 is required for running dash==2.9.3

Cassandra on Alfred is very slow, even at 1.4Ghz. The best solution is to use a device or a container (Proxmox, Docker, ...).

To get Python 10.9 or 10.10 on Alfred :

• You need to update Alfred sdcard to Buster :
  sudo nano /etc/apt/sources.list
  => buster

sudo nano /etc/apt/sources.list.d/raspi.list
=> buster

sudo apt update
sudo apt upgrade

sudo apt-get clean

sudo apt full-upgrade

sudo apt remove --purge "python2"
sudo apt autoremove --purge

Python 10 :

sudo apt install libssl-dev tk-dev libncurses5-dev libncursesw5-dev libdb5.3-dev libgdbm-dev libsqlite3-dev -dev liblzma-dev libffi-dev libgeos-dev libjpeg-dev

wget https://www.python.org/ftp/python/3.10.12/Python-3.10.12.tgz
tar -zxvf Python-3.10.12.tgz

cd Python-3.10.12
./configure --enable-optimizations
sudo make altinstall

Good luck, it takes a long time

For big maps like yours it make sense to use more powerful computer but for small maps my raspberry 3B+ is more then enough. I think banana pi will be also OK
