Fix loaded_token reference before definition

[eminn]

The below check fails when token is provided for loading textual inversion from a file (e.g. safetensors) as loaded_token variable is not defined.

if token is not None and loaded_token != token:
    logger.info(f"The loaded token: {loaded_token} is overwritten by the passed token {token}.")
else:
    token = loaded_token

Fails with:

  File "/zzzzz", line 699, in load_textual_inversion
    if token is not None and loaded_token != token:
       │                                     └ 'zzzz'
       └ 'zzzz'

UnboundLocalError: cannot access local variable 'loaded_token' where it is not associated with a value

@williamberman do you mind having a look, it's a one-liner blocking us to use textual inversions

[williamberman]

Nice! I think this is right, cc @patrickvonplaten can you double check, I'm not as familiar with this part of the code

Looks good to me, thanks!

Great!
