 First, you need to unshard model checkpoints to a single file. Let's do this for 30B model.
 
 ```
-python merge_weights.py --input_dir D:\Downloads\LLaMA --model_size 30B
+python merge-weights.py --input_dir D:\Downloads\LLaMA --model_size 30B
 ```
 
 In this example, D:\Downloads\LLaMA is a root folder of downloaded torrent with weights.
