No matter what I put: `ValueError: The initializer token must be a single token.`

[openSourcerer9000]

So I'm trying to finetune an SD model using some images. I want to add the 2 keywords (tokens?) pmauritania and cafrica, letting the model associate all images with both, and using mauritania and africa as vector points to start from when learning these words. I want to be able to prompt my model with these and have it produce results associated with these initializer words, as well as the images I'm giving it. I added both of these keywords at the beginning of the image captions, which I wrote to .txt files in the same folder, with the same name as the corresponding jpgs:

SET MODEL_NAME="C:\Users\seanrm100\Desktop\Docs\Art\StableDiffuzion\finechune\vodka.pt"
SET INSTANCE_DIR="temp"
SET OUTPUT_DIR="loras"

  --device="cuda:0" ^
  --lora_rank=1 ^
@REM  --use_face_segmentation_condition^
pause

I get

PTI : Placeholder Tokens ['<pmauritania>']
PTI : Initializer Tokens ['<mauritania>']
...
raise ValueError("The initializer token must be a single token.") ValueError: The initializer token must be a single token.

So I try using only 1 token
--placeholder_tokens="pmauritania" ^
--initializer_tokens="mauritania" ^

same thing.

--placeholder_tokens="" ^
--initializer_tokens="mauritania" ^
and
--placeholder_tokens="" ^
--initializer_tokens="" ^

same thing. Am I understanding this usage correctly? Documentation is lacking on how to caption the images, how exactly to use these args, etc.
