What does the error message "ImportError: cannot import name 'LLaMATokenizer' from 'transformers'" mean?

edit

The error message "ImportError: cannot import name 'LLaMATokenizer' from 'transformers'" means that the Python script is unable to import the class 'LLaMATokenizer' from the 'transformers' module. This could be due to a few reasons such as the module could be missing or not installed properly, the module version might have changed, or the class name might have been misspelled.
