### Who can help?

@ArthurZucker @younesbelkada 

### Information

- [X] The official example scripts
- [ ] My own modified scripts

### Tasks

- [X] An officially supported task in the `examples` folder (such as GLUE/SQuAD, ...)
- [ ] My own task or dataset (give details below)

### Reproduction

I converted the LLaMA weights to the HuggingFace format from the script in the documentation 
```
python src/transformers/models/llama/convert_llama_weights_to_hf.py \
    --input_dir /path/to/downloaded/llama/weights --model_size 7B --output_dir /output/path
```

When I try and load the tokenizer as follows
```
>>> from transformers import LlamaTokenizer
>>> tokenizer = LlamaTokenizer.from_pretrained('path_to_converted_llama_model')
```
I get the following error
```
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.8/dist-packages/transformers/tokenization_utils_base.py", line 1811, in from_pretrained
    return cls._from_pretrained(
  File "/usr/local/lib/python3.8/dist-packages/transformers/tokenization_utils_base.py", line 1965, in _from_pretrained
    tokenizer = cls(*init_inputs, **init_kwargs)
  File "/usr/local/lib/python3.8/dist-packages/transformers/models/llama/tokenization_llama.py", line 78, in __init__
    self.sp_model.Load(vocab_file)
  File "/usr/local/lib/python3.8/dist-packages/sentencepiece/__init__.py", line 905, in Load
    return self.LoadFromFile(model_file)
  File "/usr/local/lib/python3.8/dist-packages/sentencepiece/__init__.py", line 310, in LoadFromFile
    return _sentencepiece.SentencePieceProcessor_LoadFromFile(self, arg)
```
I have the following versions of the library
```
transformers            4.28.0.dev0 (installed from source though pip install git+https://github.com/huggingface/transformers.git)
sentencepiece           0.1.97
```


### Expected behavior

The tokenizer should get loaded be able function properly without the aformentioned errors

### Edit
The tokenizer.model file was corrupted which caused this issue, once that was fixed, conversion and tokenization works. 
closing this issue now
