when I use convert.py to convert llama13b to GGUF format, give me a bug, that is Why do I get prompted when I use convert.py to convert llama13b to GGUF format, zipfile.BadZipFile: File is not a zip file, but llama 7b is ok .
llama13b have two model weight consolidated.00.pth and consolidated.01.pth 。llama7b have one model weight consolidated.00.pth 。
How do I need to deal with it?
the bug is
