vintage lens

 




Vintage~1980 500mm f8 Infinity isn't infinity.
Focus the moon until it is sharp. Keep that focus.

Here is the definitive solution:





py3.14 google-crc32c


Warning message launching setiastrosuitepro:

sasp-314/venv/lib/python3.14/site-packages/google_crc32c/__init__.py:29: RuntimeWarning: As the c extension couldn't be imported, google-crc32c is using a pure python implementation that is significantly slower. If possible, please configure a c build environment and compile the extension warnings.warn(_SLOW_CRC32C_WARNING, RuntimeWarning)

So, we activate the source venv and...
pip install -U google-crc32c

Install the toolkit:
sudo apt install nvidia-cuda-toolkit

Launch setiastrosuitepro.py. It will create the runtime venv on the first start at:
~/.local/share/SASpro/runtime/py31x

Activate the venv (under py312 or py314)
Than it's simply:

cd ~/.local/share/SASpro/runtime/py312
or, depending upon which python version you used to build the git:
cd ~/.local/share/SASpro/runtime/py314

. venv/bin/activate

Install torch:
pip install torch==2.10.0 torchvision==0.25.0 --index-url https://download.pytorch.org/whl/cu126

OR for py3.14 simply:
pip install torch torchvision --index-url https://download.pytorch.org/whl/cu126
Which pulls torch 2.13.0 and torchvision 0.28.0 instead


Don't forget to install some models:



Thrash it for a while. CC denoise is good for that. Then check the thermals:
