Hi Gilles, Dragonlost,

thank-you for sharing on github, nice work!
master branch runs perfectly on ubuntu 18.10.
With beta branch I'm getting errors when I click Play and for alpha branch
I'm not seeing any stack image: the log feed cycles only on two images seemingly:
Read New image ...
Read First image ...
Happy to be a tester if you want one. I'm keen to try this on my rpi 3b+ .

best regards,
Dean

With public outreach in mind, it might be a good idea to generate a QR code for people to access a the stacked images over the proposed hotspot access point along with some fields to enter file name tags for What, Where and When.

Hi,

How are we going to create a menu shortcut or desktop shortcut for als?

Hi
This will be taken care of in the next release, along with github.com/gehelem/als/issues/59
In the meantime, you still can create en desktop entry pointing to als wherever it is currently located

Cheers

I tried to install according with the github instructions, but the system shows the following errors:

ERROR: Could not find a version that satisfies the requirement PyQt5==5.13.0 (from -r /home/astroberry/als/requirements.txt (line 6)) (from versions: 5.14.0, 5.14.1)
ERROR: No matching distribution found for PyQt5==5.13.0 (from -r /home/astroberry/als/requirements.txt (line 6))

How I can solve these errors?.

Thanks,

Jose

Looks like the version of PyQt5 that you have is too old. Try

pip install PyQt5

or possibly

pip3 install PyQt5

Hi,

From the name of the system user shown in your error report, I assume you are trying to run ALS on a raspberryPi, right ?

Here are the steps I used to get it running perfect on a rpi4 with an up-to-date RaspBian system.
$ sudo apt-get install python3-opencv python3-pyqt5 libraw-dev llvm pyqt5-dev-tools libatlas-base-dev libjpeg-dev
$ git clone https://github.com/gehelem/als.git
$ cd als
$ python3 -m venv --system-site-packages venv
$ source venv/bin/activate
$ pip install --upgrade pip
# IMPORTANT : remove pyqt5 et opencv entries from requirements.txt
$ pip install -I -r requirements.txt
$ python setup.py develop
$ als

Hope you can adapt this to you particular system, if needed

The catch here, is that the OpenCV & PyQt5 we need are not available for the ARM platform on PyPi.
Hence the system-wide install at the beginning and the important "--system-site-packages" flag used when creating the Python virtual env

Looking forward to reading about your progress
