Known Issues
ValueError: Non-consecutive added token '<|startoftext|>' found. Should have index 49408 but has index 49406 in saved vocabulary.
To resolve this, locate your huggingface hub cache directory.
It will be something like ~/.cache/huggingface/hub/path_to_lcm_dreamshaper_v7/tokenizer/. On Windows, it will roughly be C:\Users\YourUserName\.cache\huggingface\hub\models--SimianLuo--LCM_Dreamshaper_v7\snapshots\c7f9b672c65a664af57d1de926819fd79cb26eb8\tokenizer\.
