🔥 Update
- [2023/06/14] Releasing detailed instruction data and scripts on @InstructMT.
- The WMT22 test sets are made available.
- For medium-to-small models (e.g., 7B), we recommend ZeRO2+offload rather than ZerO3; use gradient accumulation to maximize GPU usage.
- Important optimizations:
preprocess_function
to be 4-5X faster;DataCollatorForSeq2Seq
for batch-wise padding to save 5-10% GPU usage. - Introducing ParroT-LoRA which supports saving and restarting from the checkpoints (base model and lora weights) during finetuning.
- Setting the default Transformers to
>= 4.28.0.dev0
directly as it merged the PR of LLaMA. With this version on Torch 1.13.1 + CUDA 11.7, we find the finetuning process could be a bit faster (~18%) than our v1.0.0 implementation.

Parrots are smart birds that can respond to simple commands or questions. The question is whether they're just mimicking, or really intelligent enough to communicate with humans. This is similar to what we currently speculate about LLMs.
Promoting the good is essential, but punishing the evil is also necessary to ensure that goodness prevails. Similarly, aligning LLMs with human feedbacks is exactly to learn from correct examples and discriminate erroneous examples.
Large language models (LLMs) like ChatGPT and GPT-4 have exhibited remarkable abilities on a wide range of natural language processing (NLP) tasks, including various machine translation abilities accomplished during chat. However, these models are only accessible through restricted APIs, which creates barriers to new research and advancements in the field. Therefore, we propose the ParroT framework to enhance and regulate the translation abilities during chat based on open-sourced LLMs (e.g., LLaMA, Bloomz) and human written translation and evaluation data. Specifically, ParroT reformulates translation data into the instruction-following style, and introduces a “Hint” field for incorporating extra requirements to regulate the translation process.
Figure 1: Framework of ParroT. Hints are (optional) extra requirements to regulate the translation process.
- Train Data: data/data_alpaca_hf.json, data_parrot_hf.json
- You can also use Alpaca data by GPT-4: data/data_alpaca_gpt4_hf_en.json, data/data_alpaca_gpt4_hf_zh.json
- Test Data: Flores subsets, WMT22 test sets
- Instruction-following format:
Below is an instruction that describes a task. Write a response that appropriately completes the request.
### Instruction:
We are translating the following sentences from Chinese to English.
### Input:
检查情况显示,市场销售的粮油、肉类、水果、蔬菜、蛋奶等生活必需品供应充足,商品价格基本稳定,未发现严重违法违规行为,市场经营秩序总体平稳。
### Hint: A translation with major accuracy/mistranslation errors could be
### Response:The results of the inspection indicate the sufficient supply of living necessities <v>on marketing</v>
including cereals and oils, meat, fruits, vegetables, eggs and milk, and the basically stabilized commodity price.
The inspection hasn’t found serious violation of laws and regulations. The market order is stable on an overall basis.
We develop ParroT based on open-sourced LLMs (e.g., LLaMA, Bloomz) with HuggingFace's transformers library.
Framework Versions:
- Python 3.8.12
- Pytorch 1.13.1+cu117
- Transformers (git+https://github.com/huggingface/transformers.git)
- Peft (git+https://github.com/huggingface/peft.git)
- Other requirements

Convert the regular bilingual sentence pairs into Alpaca data format:
python3 scripts/convert_pair_to_alpaca.py \
-s zh -t en \
-if scripts/instruct_follow.txt \
-sf data/train.zh-en.zh.txt \
-tf data/train.zh-en.en.txt \
-of data/train_alp.json
Convert the Alpaca data format to the training data format here:
python3 scripts/convert_alpaca_to_hf.py \
-i data/train_alp.json \
-o data/train_alp_hf.json
We modify the example script of language modeling in transformers for finetuning, i.e., run_clm.py
with the built in HuggingFace Trainer
.
So it would be easy to get started if you are familiar with run_clm.py
. Also, this script supports data streaming, which might be helpful for handling larger datasets. DeepSpeed ZeRO stage 2/3 is adopted for distributed training.
The resulting finetuning scripts are named as run_clm_llms.py
and run_clm_lora.py
for full model training and LoRA training, respectively.
Theoretically, the run_clm_lora.py
script can handle both full model and LoRA by specifying the arguments. But we also keep the former one for full model in consideration of safe development.
For LoRA training, we recommend to use ZeRO2 since ZeRO3 is very unstable when saving adapter_model.bin
.

The scripts support generation with and without hints using different instructions.
The hints are appended to the default instruction with ###
as a delimiter.
Simply switch the inference instruction for different strategies.

Currently, we finetuned the following LLMs for ParroT with the evaluation mainly on WMT22 test sets.
- LLaMA-7b
- Bloomz-mt-7b
- ParroT-LoRA
- 8bit Training (high requirements for both environments and GPU types)
There are several interesting observations:
- ParroT based on Bloomz-mt-7b also works well with hints. Besides, Bloomz-mt-7b shows stronger ability in the modeling of Chinese texts.
- LoRA seems to prevent LLMs from overfitting which benefits the high-resource De-En translation but restricts the instruction learning of other directions. The limited trainable parameters (only ~4.2M) may explain this observation.
Try llama.cpp to run the LLMs using 4-bit quantization on a MacBook.
We adopt a specific fork from comex/llama.cpp which supports the conversion of HuggingFace models to ggml
format.
We recommend the use of Python 3.10.10 for convert.py
since we encountered bugs with Python 3.9.5.
