## CodeSage-Large |
|
|
|
### Model description |
|
CodeSage is a new family of open code embedding models with an encoder architecture that support a wide range of source code understanding tasks. It is introduced in the paper: |

|
|
|
### Pretraining data |
|
This checkpoint is trained on the Stack data (https://huggingface.co/datasets/bigcode/the-stack-dedup). Supported languages (9 in total) are as follows: c, c-sharp, go, java, javascript, typescript, php, python, ruby. |
|
|
|
### Training procedure |
|
This checkpoint is first trained on code data via masked language modeling (MLM) and then on bimodal text-code pair data. Please refer to the paper for more details. |
|
|
|
### How to use |
|
This checkpoint consists of an encoder (356M model), which can be used to extract code embeddings of 2048 dimension. It can be easily loaded using the AutoModel functionality and employs the Starcoder tokenizer (https://arxiv.org/pdf/2305.06161.pdf). |
|
|
|
``` |
|
from transformers import AutoModel, AutoTokenizer |
|
|
|
checkpoint = "codesage/codesage-base" |
|
device = "cuda" # for GPU usage or "cpu" for CPU usage |
|
|
|
tokenizer = AutoTokenizer.from_pretrained(checkpoint, trust_remote_code=True) |
|
model = AutoModel.from_pretrained(checkpoint, trust_remote_code=True).to(device) |
|
|
|
inputs = tokenizer.encode("def print_hello_world():\tprint('Hello World!')", return_tensors="pt").to(device) |
|
embedding = model(inputs)[0] |
|
print(f'Dimension of the embedding: {embedding[0].size()}') |
|
# Dimension of the embedding: torch.Size([13, 1024]) |
|
``` |
