# CodeParrot 🦜 (small) |
|
|
|
CodeParrot 🦜 is a GPT-2 model (110M parameters) trained to generate Python code. |
|
|
|
## Usage |
|
|
|
You can load the CodeParrot model and tokenizer directly in `transformers`: |
|
|
|
```Python |
|
from transformers import AutoTokenizer, AutoModelWithLMHead |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("codeparrot/codeparrot-small") |
|
model = AutoModelWithLMHead.from_pretrained("codeparrot/codeparrot-small") |
|
|
|
inputs = tokenizer("def hello_world():", return_tensors="pt") |
|
outputs = model(**inputs) |
|
``` |
|
|
|
or with a `pipeline`: |
|
|
|
```Python |
|
from transformers import pipeline |
|
|
|
pipe = pipeline("text-generation", model="codeparrot/codeparrot-small") |
|
outputs = pipe("def hello_world():") |
|
``` |
|
|
|
## Training |
|
|
|
The model was trained on the cleaned [CodeParrot 🦜 dataset](https://huggingface.co./datasets/codeparrot/codeparrot-clean) with the following settings: |
|
|
|
|Config|Value| |
|
|-------|-----| |
|
|Batch size| 192 | |
|
|Context size| 1024 | |
|
|Training steps| 150'000| |
|
|Gradient accumulation| 1| |
|
|Gradient checkpointing| False| |
|
|Learning rate| 5e-4 | |
|
|Weight decay | 0.1 | |
|
|Warmup steps| 2000 | |
|
|Schedule| Cosine | |
|
|
|
The training was executed on 16 x A100 (40GB) GPUs. This setting amounts to roughly 29 billion tokens. |
|
|
|
## Performance |
|
|
|
We evaluated the model on OpenAI's [HumanEval](https://huggingface.co./datasets/openai_humaneval) benchmark which consists of programming challenges: |
|
|
|
| Metric | Value | |
|
|-------|-----| |
|
|pass@1 | 3.80% | |
|
|pass@10 | 6.57% | |
|
|pass@100 | 12.78% | |
|
|
|
The [pass@k metric](https://huggingface.co./metrics/code_eval) tells the probability that at least one out of k generations passes the tests. |
