# Llama-3-15B-Instruct-zeroed-ft |
|
|
|
This is a QLoRA **finetune** of a merge of pre-trained language models created using [mergekit](https://github.com/cg123/mergekit). |
|
|
|
The model is based on a "zeroed" passthrough merge of [Llama-3-15B-Instruct-zeroed](https://huggingface.co/elinas/Llama-3-15B-Instruct-zeroed) |
|
|
|
This was primarily an experiment to see how a passthrough merge will respond to further finetuning, though this was done on a small dataset. |
|
|
|
The model was finetuned on **8192 context length** and is likely reliable using RoPE up to 32k. |
|
|
|
Further finetuning this model or finetuning the [base model](https://huggingface.co/elinas/Llama-3-15B-Instruct-zeroed) on more samples is encouraged. |
|
|
|
## Datasets |
|
|
|
* [Chat-Error/Pure-dove-sharegpt](https://huggingface.co/datasets/Chat-Error/Pure-dove-sharegpt) |
|
|
|
A small, high quality, dataset was used as a PoC / validation on stabilizing the model after finetuning. |
|
|
|
## Finetuning details |
|
This is a QLoRA model and the following modules were targeted. |
|
```yaml |
|
lora_target_modules: |
|
- down_proj |
|
- o_proj |
|
``` |
|
|
|
The model is coherent even with training the "zeroed" layers and can write well. In the next experiment, all layers will be finetuned as this was |
|
the recommendation from [Charles Goddard](https://huggingface.co/chargoddard) - thank you for sharing the method of merging as well as Toasty |
|
Pigeon for bringing it to my attention! |
|
|
|
```yaml |
|
The following hyperparameters were used during training: |
|
- learning_rate: 1e-05 |
|
- train_batch_size: 2 |
|
- eval_batch_size: 2 |
|
- seed: 42 |
|
- distributed_type: multi-GPU |
|
- num_devices: 3 |
|
- total_train_batch_size: 6 |
|
- total_eval_batch_size: 6 |
|
- optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08 |
|
- lr_scheduler_type: cosine |
|
- lr_scheduler_warmup_steps: 25 |
|
- num_epochs: 1 |
|
``` |
|
|
|
Optimizer `paged_adamw_8bit` and Deepspeed ZeRO 3 was used at a LR of `1e-5` using the cosine scheduler for 1 epoch on 3x3090s taking 4h 12m 13s total. |
|
|
|
Sample packing and padding was disabled to reduce VRAM consumption significantly at the cost of speed. |
