@s3nh Will your converted model can run on colab's CPU easily?

@deepakkaura26 I think so! by default you get 2 vCPUs on colab with 13G RAM which should be enough to run the ggml versions

@mauriceweber actually I tried it but whether I choose CPU or GPU my colab got crashed 5 times.

Which quantization did you try? I tried the 4bit version on colab and could run it without problems.

import ctransformers
from ctransformers import AutoModelForCausalLM

model_file = "LLaMA-2-7B-32K.ggmlv3.q4_0.bin"
model = AutoModelForCausalLM.from_pretrained("s3nh/LLaMA-2-7B-32K-GGML",  model_type="llama", model_file=model_file)

prompt = "Whales have been living in the oceans for millions of years "
model(prompt, max_new_tokens=128, temperature=0.9, top_p= 0.7)

EDIT: load model directly from hub.

@mauriceweber I have use this same example which is present in this model website

from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("togethercomputer/LLaMA-2-7B-32K")
model = AutoModelForCausalLM.from_pretrained("togethercomputer/LLaMA-2-7B-32K", trust_remote_code=True, torch_dtype=torch.float16)

input_context = "Your text here"
input_ids = tokenizer.encode(input_context, return_tensors="pt")
output = model.generate(input_ids, max_length=128, temperature=0.7)
output_text = tokenizer.decode(output[0], skip_special_tokens=True)
print(output_text)

@mauriceweber I tried to run your codes which you showed they give me this following error

HTTPError Traceback (most recent call last)

The above exception was the direct cause of the following exception:

Here you are not using the quantized (ggml) models, which is why you are running out of memory (you need around 14GB RAM for the 7B model with float16).

@mauriceweber I tried to run your codes which you showed they give me this following error

This is error is because the model is not downloaded yet (I was assuming you had it downloaded to colab) -- I adjusted the code snippet above so that the model file gets pulled directly from the repo. You can check the other model versions here.

Let us know how it goes!:)

Is this model already trained? running the example code just gives me this:
