Error when transferring control

[f8upd8]

Traceback:

(control) malo@win11-f8:/mnt/i/source/ControlNet$ python tool_transfer_control.py
logging improved.
Loaded state_dict from [/mnt/i/ckpt/native/sd1-5pruned.ckpt]

KeyError: 'first_stage_model.encoder.conv_in.weight'

I suggest changing

if is_first_stage or is_cond_stage:
    final_state_dict[key] = input_state_dict[key]
    continue

to

if is_first_stage or is_cond_stage:
    if not input_state_dict.get(key):
        continue
    final_state_dict[key] = input_state_dict[key]
    continue

This will ensure script does not die if one model has a state key that other does not. This helped me to transfer models to novelai.

Sorry for being lazy with PRs
