I've had a go at using Starnet++, downloaded it found a tutorial to watch as I had absolutely no idea how to actually run it and can't seem to get it to work as I think I'm not doing something quite right. I'm using a Mac and also Affinity Photo and I can get it to run on the image but the final result just turns out as a black image. The shell script just tells me that 'AdobeDeflate Compression support is not configured' I've tried to have a search to see what that means but can't seem to find out what it actually is. I'm not the most tech savvy person so any help would be massively appreciated. I was going to post a screen shot but I cannot even figure out how to do that, hahaha.
It's been a while since I ran StarNet++ on its own outside of PixInsight. I don't know how much help I can offer you regarding that AdobeDeflate thing.
Make sure you're running starnet on a non-linear (i.e. stretched) image. Running it on a linear image would lead to just getting a black result.
Are you using an Intel-based Mac, or one of the newer M1 Macs? I think some people had issues with running it on the M1 Macs (but maybe that's been solved). Anyway, on my Mac (a 2019 MacBook Pro with 8 core i9, Radeon 560X, 16G RAM) I can run it on the command line. I just downloaded and tested it out.
Step 1, download the zip
Step 2, extract the zip
Step 3, open up a terminal (Applications -> Utilities -> Terminal)
Step 4, go to where you unzipped that file. If that was to your Downloads folder, and you unzipped it there, then you'd type: cd ~/Downloads/StarNet_MacOS and hit return
Step 5, you have to change permissions to allow it to be run, so type: chmod 755 * and then hit return
Step 6, you need to get it out of quarantine, so type: xattr -dr com.apple.quarantine * and then hit return
Step 7, run it on the test image provided: ./run_rgb_starnet.sh and hit return
You should see something like the following text:
Reading input image... Done!
Bits per sample: 16
Samples per pixel: 3
Restoring neural network checkpoint... Done!

If you get something similar, you'll have a new, starless image in that same directory called rgb_test5_s.tif
Hopefully that helps a bit.
