test_dataset_Codellama-3-8B

Please note this model is a test, the full finetuned version can be found here: https://huggingface.co/rombodawg/Llama-3-8B-Instruct-Coder

GOOGLE COLAB IS A SCAM DO NOT USE THE PAID VERSION

THEY WILL DISCONNECT YOUR RUNTIME BEFORE EVEN 24 HOURS

PLEASE INSTEAD USE TENSORDOCK ITS CHEAPER AND DOESNT DISCONNECT YOU

This is unsloth/llama-3-8b-Instruct trained on the Replete-AI/code-test-dataset using the code bellow with unsloth and google colab with under 15gb of vram. This training was complete in about 40 minutes total.

Colab doc if you dont want to copy the code by hand:

Copy from my announcement in my discord:

If anyone wants to train their own llama-3-8b model for free on any dataset
 that has around 1,500 lines of data or less you can now do it easily by using
 the code I provided in the model card for my test model in this repo and
 google colab. The training for this model uses (Unsloth + Qlora + Galore) to
 achieve the ability for training under such low vram. 

For anyone that is new to coding and training Ai, all your really have to edit is

1. (max_seq_length = 8192) To match the max tokens of the dataset or model you are using
2. (model_name = "unsloth/llama-3-8b-Instruct",) Change what model you are finetuning, this setup is specifically for llama-3-8b
3. (alpaca_prompt =) Change the prompt format, this one is setup to meet llama-3-8b-instruct format, but match it to your specifications.
4. (dataset = load_dataset("Replete-AI/code-test-dataset", split = "train")) What dataset you are using from huggingface
5. (model.push_to_hub_merged("rombodawg/test_dataset_Codellama-3-8B", tokenizer, save_method = "merged_16bit", token = ""))
6. For the above you need to change "rombodawg" to your Hugginface name, "test_dataset_Codellama-3-8B" to the model name you want saved as, and in token = "" you need to put your huggingface write token so the model can be saved.
