With many .safetensors
files associated to different LoRA authors sometimes specify "trigger words".
I've been trying to extract find the way to extract them from .safetensors
file but I cannot find them. They are not present in metadata section and according to documentation I cannot think of other place where those can be.
On the other hand, I know that those trigger words are working, because I am getting image generated when I'm providing them.
I thought that something like this will work: from safetensors import safe_open
tensors = {}
with safe_open("lora.safetensors", framework="pt") as f:
print(f.metadata())
But it seems the access is more complicated. Any suggestion?
Adapting from https://huggingface.co/docs/safetensors/metadata_parsing#python:
import json
import struct
with open("lora.safetensors", "rb") as f:
length_of_header = struct.unpack('<Q', f.read(8))[0]
header_data = f.read(length_of_header)
header = json.loads(header_data)
print(header) # should be a dict that contains what you need
