Libraries

How to use togethercomputer/LLaMA-2-7B-32K with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="togethercomputer/LLaMA-2-7B-32K")

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("togethercomputer/LLaMA-2-7B-32K")
model = AutoModelForCausalLM.from_pretrained("togethercomputer/LLaMA-2-7B-32K")

Fix RuntimeError: pad attn scores back to original query sequence length, instead of unpadded sequence length (i.e. no change).

Prevents RuntimeError on line 382's pad_input(…).reshape()
shape '[1, 4096, 4096]' is invalid for input of size 9400320

before this change, pad_input() was basically just doing a .unsqueeze(0):
attn_output.shape
torch.Size([2295, 32, 128])
pad_input(attn_output, indices_q, bsz, max_seqlen_q).shape
torch.Size([1, 2295, 32, 128])

after this change: pad_input actually pads the input back to the original query sequence length:
pad_input(attn_output, indices_q, bsz, q_len).shape
torch.Size([1, 4096, 32, 128])
and the reshape succeeds:
pad_input(attn_output, indices_q, bsz, q_len).reshape(bsz, q_len, h_size).shape
torch.Size([1, 4096, 4096])

Fix RuntimeError: pad attn scores back to original query sequence length, instead of unpadded sequence length (i.e. no change).e6c58dac
