# GPT2 for Code AutoComplete Model
|
17 |
+
code-autocomplete, a code completion plugin for Python.
|
18 |
+
|
19 |
+
**code-autocomplete** can automatically complete the code of lines and blocks with GPT2.
|
20 |
+
|
21 |
+
## Usage
|
22 |
+
|
23 |
+
Open source repo:[code-autocomplete](https://github.com/shibing624/code-autocomplete),support GPT2 model, usage:
|
24 |
+
|
25 |
+
```python
|
26 |
+
from autocomplete.gpt2_coder import GPT2Coder
|
27 |
+
|
28 |
+
m = GPT2Coder("shibing624/code-autocomplete-distilgpt2-python")
|
29 |
+
print(m.generate('import torch.nn as')[0])
|
30 |
+
```
|
31 |
+
|
32 |
+
Also, use huggingface/transformers:
|
33 |
+
|
34 |
+
*Please use 'GPT2' related functions to load this model!*
|
35 |
+
|
36 |

```python

Pretrained model on English language using a causal language modeling (CLM) objective. It was introduced in
|
121 |
+
[this paper](https://d4mucfpksywv.cloudfront.net/better-language-models/language_models_are_unsupervised_multitask_learners.pdf)
|
122 |

and first released at [this page](https://openai.com/blog/better-language-models/).

Disclaimer: The team releasing GPT-2 also wrote a
|
125 |
+
[model card](https://github.com/openai/gpt-2/blob/master/model_card.md) for their model. Content from this model card
|
126 |
+
has been written by the Hugging Face team to complete the information they provided and give specific examples of bias.
