Bug: exception while rasing a another exception in convert_llama_ggml_to_gguf script

[farbodbj]

What happened?

When trying to convert this GGML model from hugging face to GGUF, the script encountered an error in this function but when trying to raise the ValueError it encountered another exception. how I called the python script: python convert_llama_ggml_to_gguf.py --input models/bigtrans-13b.ggmlv3.q6_K --output q6_K as it is obvious an input with wrong data type (int instead of GGMLQuantizationType) has been passed to this function. I fixed this issue in #8928
