standalone "Make an embedding file for SD", but non-conventional
Browse filesNote: this currently does NOT PERFORM AS EXPECTED.
Making an embedding from the word "cat" does not give you consistent images of cats.
It's more like "suggestion of cats".

""" Work in progress
|
| 4 |
+
NB: This is COMPLETELY DIFFERENT from "generate-embeddings.py"!!!
|
| 5 |
+
|
| 6 |
+
|
| 7 |
+
Plan:
|
| 8 |
+
Take input for a single word or phrase.
|
| 9 |
+
Generate a embedding file, "generated.safetensors"
|
| 10 |
+
Save it out, to "generated.safetensors"
|
| 11 |
+
|
| 12 |
+
Note that you can generate an embedding from two words, or even more
|
| 13 |
+
|
| 14 |
+
Note also that apparently there are multiple file formats for embeddings.
|
| 15 |
+
I only use the simplest of them, in the simplest way.
