Google colab import checkpoint error

[Bleestra]

I trained the stable diffusion model on v2-1_512-ema-pruned.ckpt via Google colab, downloaded, uploaded it to the hugging face, downloaded.ckpt file , uploaded to stable-diffusion-webui-1.7.0\models\Stable-diffusion , selected the model in the web interface and displays the following error in the terminal:

changing setting sd_model_checkpoint to Game_Character_v2.ckpt: AttributeError

How fix it?
