I am receiving an error while trying to load TheBloke/Llama-2-70B-Chat-GGML. Can anyone provide me with error clarification or assistance?
Here is the link to the GitHub repository that can help you gain a better understanding of errors.
The code I have is
llm = LlamaCpp(
model_path=model_path,
max_tokens=256,
n_gpu_layers=n_gpu_layers,
n_batch=n_batch,
callback_manager=callback_manager,
n_ctx=1024,
verbose=False,
)

• and the error I am getting is
  AssertionError Traceback (most recent call last)

  ----> 1 lcpp_llm = Llama(
