# finetune

|

Basic usage instructions:
|
||||
|
||||
```bash
|
||||
# get training data
|
||||
wget https://raw.githubusercontent.com/brunoklein99/deep-learning-notes/master/shakespeare.txt
|
||||
|
||||
# finetune LORA adapter
|
||||
./bin/llama-finetune \
|
||||
--model-base open-llama-3b-v2-q8_0.gguf \
|
||||
--checkpoint-in chk-lora-open-llama-3b-v2-q8_0-shakespeare-LATEST.gguf \
|
||||
--checkpoint-out chk-lora-open-llama-3b-v2-q8_0-shakespeare-ITERATION.gguf \
|
||||
--lora-out lora-open-llama-3b-v2-q8_0-shakespeare-ITERATION.bin \
|
||||
--train-data "shakespeare.txt" \
|
||||
--save-every 10 \
|
||||
--threads 6 --adam-iter 30 --batch 4 --ctx 64 \
|
||||
--use-checkpointing
|
||||
|
||||
# predict
|
||||
./bin/llama-cli -m open-llama-3b-v2-q8_0.gguf --lora lora-open-llama-3b-v2-q8_0-shakespeare-LATEST.bin
|
||||
```
|
||||
|
||||
**Only llama based models are supported!** The output files will be saved every N iterations (config with `--save-every N`).
|
||||
The pattern 'ITERATION' in the output filenames will be replaced with the iteration number and with 'LATEST' for the latest output.
|
||||
So in above example after 10 iterations these files will be written:
|
||||
- chk-lora-open-llama-3b-v2-q8_0-shakespeare-10.gguf
|
||||
- chk-lora-open-llama-3b-v2-q8_0-shakespeare-LATEST.gguf
|
||||
- lora-open-llama-3b-v2-q8_0-shakespeare-10.bin
|
||||
- lora-open-llama-3b-v2-q8_0-shakespeare-LATEST.bin
|
||||
|
||||
After 10 more iterations:
|
||||
- chk-lora-open-llama-3b-v2-q8_0-shakespeare-20.gguf
|
||||
- chk-lora-open-llama-3b-v2-q8_0-shakespeare-LATEST.gguf
|
||||
- lora-open-llama-3b-v2-q8_0-shakespeare-20.bin
|
||||
- lora-open-llama-3b-v2-q8_0-shakespeare-LATEST.bin
|
||||
|
||||
Checkpoint files (`--checkpoint-in FN`, `--checkpoint-out FN`) store the training process. When the input checkpoint file does not exist, it will begin finetuning a new randomly initialized adapter.
|
||||
|
||||
llama.cpp compatible LORA adapters will be saved with filename specified by `--lora-out FN`.
|
||||
These LORA adapters can then be used by `llama-cli` together with the base model, like in the 'predict' example command above.
|
||||
|
||||
In `llama-cli` you can also load multiple LORA adapters, which will then be mixed together.
|
||||
|
||||
For example if you have two LORA adapters `lora-open-llama-3b-v2-q8_0-shakespeare-LATEST.bin` and `lora-open-llama-3b-v2-q8_0-bible-LATEST.bin`, you can mix them together like this:
|
||||
|
||||
```bash
|
||||
./bin/llama-cli -m open-llama-3b-v2-q8_0.gguf \
|
||||
--lora lora-open-llama-3b-v2-q8_0-shakespeare-LATEST.bin \
|
||||
--lora lora-open-llama-3b-v2-q8_0-bible-LATEST.bin
|
||||
```
|
||||
|
||||
You can change how strong each LORA adapter is applied to the base model by using `--lora-scaled FN SCALE` instead of `--lora FN`.
|
||||
|
||||
For example to apply 40% of the 'shakespeare' LORA adapter, 80% of the 'bible' LORA adapter and 100% of yet another one:
|
||||
|
||||
```bash
|
||||
./bin/llama-cli -m open-llama-3b-v2-q8_0.gguf \
|
||||
--lora-scaled lora-open-llama-3b-v2-q8_0-shakespeare-LATEST.bin 0.4 \
|
||||
--lora-scaled lora-open-llama-3b-v2-q8_0-bible-LATEST.bin 0.8 \
|
||||
--lora lora-open-llama-3b-v2-q8_0-yet-another-one-LATEST.bin
|
||||
```
|
||||
|
||||
The scale numbers don't need to add up to one, and you can also use numbers greater than 1 to further increase the influence of an adapter. But making the values too big will sometimes result in worse output. Play around to find good values.
|
||||
|
||||
Gradient checkpointing reduces the memory requirements by ~50% but increases the runtime.
|
||||
If you have enough RAM, you can make finetuning a bit faster by disabling checkpointing with `--no-checkpointing`.
|
||||
|
||||
The default LORA rank can be specified with `--lora-r N`.
|
||||
The LORA rank can be configured for each model tensor type separately with these command line options:
|
||||
|
||||
```bash
|
||||
--lora-r N LORA r: default rank. Also specifies resulting scaling together with lora-alpha. (default 4)
|
||||
--rank-att-norm N LORA rank for attention norm tensor (default 1)
|
||||
--rank-ffn-norm N LORA rank for feed-forward norm tensor (default 1)
|
||||
--rank-out-norm N LORA rank for output norm tensor (default 1)
|
||||
--rank-tok-embd N LORA rank for token embeddings tensor (default 4)
|
||||
--rank-out N LORA rank for output tensor (default 4)
|
||||
--rank-wq N LORA rank for wq tensor (default 4)
|
||||
--rank-wk N LORA rank for wk tensor (default 4)
|
||||
--rank-wv N LORA rank for wv tensor (default 4)
|
||||
--rank-wo N LORA rank for wo tensor (default 4)
|
||||
--rank-ffn_gate N LORA rank for ffn_gate tensor (default 4)
|
||||
--rank-ffn_down N LORA rank for ffn_down tensor (default 4)
|
||||
--rank-ffn_up N LORA rank for ffn_up tensor (default 4)
|
||||
```
|
||||
|
||||
The LORA rank of 'norm' tensors should always be 1.
|
||||
|
||||
To see all available options use `llama-finetune --help`.

Output files will be saved every N iterations (config with `--save-every N`).
|
||||
The pattern "ITERATION" in the output filenames will be replaced with the iteration number and "LATEST" for the latest output.
|
||||
|
||||
To train GGUF models just pass them to `--checkpoint-in FN`.
