no module 'xformers'. Processing without...

[Albertino7]

Hello to all guys. :-)
For me an honor and pleasure to be able to write in this super forum.
I have installed stable-diffusion in my mac (of which I am attaching the system information. ).

As you can see from the screenshot, upon starting stable-diffusion I notice "alerts" such as the

no module 'xformers'. Processing without...
Style database not found: /Users/utente/Documents/AI/stable-diffusion-webui/styles.csv
Warning: caught exception 'Torch not compiled with CUDA enabled', memory monitor disabled
Loading weights [85eadcfebc] from /Users/utente/Documents/AI/stable-diffusion-webui/models/Stable-diffusion/pov oral sex_V1.safetensors
Running on local URL: http://127.0.0.1:7860

And other lines you can see ()

Also once I load the program I don't see the models present by default m it only loads the ones I manually loaded ()

Please can you help me understand if and where is the problem?
Unfortunately I am not an experienced user but I am trying to apply myself and understand.
Maybe someone else has already been in the same situation as me.

Thank you very much!

Alberto

You don't have to use xformers and this is just a warning, don't worry about it. If you use for example sdp-attention, then you will always see that message, just ignore it.

Thank you @AlekFy !
But why I don't see the default Models in the drop down menu?

[w-e-w]

if by "default model" you mean the original v1-5-pruned-emaonly.safetensors
webui only automatically downloads that model if there is no model found
and since web UI has detected that you have prepared models yourself
we don't download a model that you likely won't be using for you

we basically only added that auto download so that people don't report errors because
"image generation does not work because there's no model"

if you want that model you can download it yourself at
