I built a new release of the libtensorflow.so for ROCm 6.1.3 which supports AMD 7000 series GPUs on Ubuntu

This release also works with WSL2 Ubuntu pass through on Windows 11 (not test on Windows 10)

Basically, if you have Windows, you can install PixInsight in WSL2, apply the updated libtensorflow and use accelerated noise xterminator / star net so on and so forth.

If you have already implemented a prior version (2.16 or 2.15) i do suggest upgraded to ROCm 6.1.3 and updating to this release.

BTW, on Windows, if you run PixInsight via Ubuntu installed from the Windows Store - Windows will create a PixInsight icon for you and it works pretty well.

Just be sure to install your plugins via the set up for the Linux Version and enjoy GPU acceleration (you can see it pass through in task manager as shown on my blog)

If you run on WSL2, don't forget to increase your RAM to WSL2 -   I have 64gb of ram, so I allocated 48gb to WSL2 and i crated a HUGE 128gb swap since i do large pixinsight integrations.

Open up Powershell/cmd

In your user directory
notepad .wslconfig

edit or add -  make sure your memory is at most 75% of available ram  - so if you have 32gb of ram, memory should be 24.  swap can be as large as you need. Pixinsight loves swap during integrations and will just fail ungracefully without enough swap.
[wsl2]
memory=48GB
swap =128GB

save file
wsl ---shutdown


Then restart a terminal or re-open pixinsight (this shutdown will force a config re-read)
