GraXpert 2.0 and PixInsight Script Steffen Hirtle GraXpert · Frank Sackenheim · ... · 153 · 10935 · 15

Bruce Donzanti:
I could not get it to work within PI.  I can get it to open outside of PI but even after I added the link in your video, I get an error message- You must setup the path to GraxPert first using the wrench icon.

Bruce Donzanti:
Thanks, Frank.  But I now have another problem.  I followed your direction about the wrench, it started to open and then froze.   I did have the older version on PI before but I removed it before starting over.   After trying to close it, the GraXpert icon remained on my computer and I had to reboot to remove it.

Frank Sackenheim:
Hello,

I am Frank, founder of the GraXpert Team. Our Team has now officially released the Version 2.0 with AI functionality. Also GraXpert AI is now available as a script in PixInsight, so you can use it directly out of PI.
I have created a video to show you the installation on Mac and PC, as well as the installation of the script.

Have Fun

Bruce Donzanti:
I'm not sure if this is specific to my computer or if I did something else wrong.

Bruce Donzanti:
It may be hard to read but I get a statement saying, "MainProcess tensorflow WARNING  No training configuration found in save file, so model was *not* compiled."

Hi Frank,

thanks for all the effort you and the graxpert team have invested. 
I followed your instructions and it works well and somehow magically. 

I am interested in how it works with the AI part. I know that AI and machine learning are somehow black boxes, but it would be interesting to learn the principles of the learning process. 

Unfortunately, I did not find any information. So, is there any documentation going into more details than saying AI is applied?

Any link will be welcome. 

Thanks in advance

Hi Thomas,

we will update our documentation to fully explain what we did and which data we used. But thats all a lot of work. Hopefully we can do this until the end of the year.
Basically we did the following.
We used tensorflow as the framework for our AI, so thats a convolutional neural network.
We then used Graxpert in its former version to create images with and without gradients. In most cases we used the RBF algorithm, that was very sucessfully in GraXpert 1.0. We trained the network with those before and after images. So we can say, the network learned how to create backround models like the RBF algorithm does. As soon, as the AI creates the Model, its simply subtracted from the original image.
Thats how it works in a nutshell.

Cheers
Frank

To bad it wont start  on macos catalina 10.15.7 . its a I7 with 32 gig ram.
 install was ok etc ,also the security settings  where done.

Hi John,

can you give me a few more infos. Does Graxpert not start, do you get any message? Or does the PI Script not work?

I installed the GraXpert-macos-x86_64.dmg

Just  the way you show on youtube, and its  installed correct . i did even reboot after,but when i click the icon,it pops for 1 second and then  it stops.

Did the install twice,still the same.

Hi, I am afraid to tell you, that GraXpert works only from macOS 11.0
