The LICENSE file says everything is 3-clause BSD, which is what we want, but at some point the Apache license was added to the top of some files and that proliferated. This commit removes the Apache license from any files that we own the copyright to.

+#### SGEAT (Standard) +To perform unconditional generation for a Megatron LM, we provide an example script for 1.3B LM. + +```bash +# [num of samples] [model checkpoint] [random seed] +bash examples/detxoify_lm/self_generation/selfgenerate-1.3b-unconditional.sh 1000 checkpoints/gpt3/gpt3-1.3b/ 2333 +``` +This will generate a jsonl file of 1000 generated text (as a toy example) at `selfgeneration/unconditional_generation_gpt3-1.3b/2333.out`. + +Note that you may want to set your own gpt2 vocab and merge file dir, as well as your output data dir in `selfgenerate-1.3b-unconditional.sh`. + +### Annotation + +We then use Perspective API to annotate the self generated corpus. Note that you need to fill in your own Perspective API key in the `examples/detoxify_lm/perspective_api_annotate.py`. + +```bash +python examples/detxoify_lm/perspective_api_annotate.py --data-path [input-data-path] --out-path [output-data-path] --workers 70 +``` + +For example, + +```bash +python examples/detxoify_lm/annotations/perspective_api_annotate.py --data-path selfgeneration/unconditional_generation_gpt3-1.3b/2333.out --out-path selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.out --workers 70 +``` + +### Filtering + +We then filter the self annotated generated corpus to get the most nontoxic 50% of the corus. + +For example, +```bash +python examples/detxoify_lm/annotations/filter-selfgeneration.py --data-path selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.out --out-path selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic.out +``` + +This will generate a jsonl file of 500 text of the lowest toxicity (as a toy example) at `selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic.out`. + + +### Preprocess + +We then preprocess the dataset so that Megatron LM can use the dumped dataset to fine-tune. + +``` +bash examples/detxoify_lm/annotations/preprocess.sh selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic.out selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic +``` + +This will generate two files as follows +```bash +selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic_text_document.idx +selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic_text_document.bin +``` +which will be used in the following domain-adative training step. + +### Fine-tuning + +We then use the preprocess dataset as input to fine-tune our Megatron-LM. +```bash +# [fine-tuning dataset] [output-dir] [lr] [bs] [train-iters] [load checkpoint] +bash examples/detxoify_lm/finetune_gpt_distributed-1.3b.sh selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic_text_document gpt3-1.3b-toy-example-lr-2e-5-bs-512 2e-5 512 78 checkpoints/gpt3/gpt3-1.3b +``` + +This will dump the final checkpoint in `$SHARE_DATA/gpt3-1.3b-toy-example-lr-2e-5-bs-512`. (`$SHARE_DATA` is your current work dir, default to `$PWD`) + +### Evaluation + +We then use the fine-tuned checkpoint to perform conditional generation given RealToxicityPrompts: + +```bash +#
