# Chat-Vector-LLaVA-v1.5-7b-JA Model Card |
|
## Model detail |
|
**Model type:** |
|
Chat-Vector-LLaVA-v1.5-7b-JA is a vision-language model that can converse about input images in Japanese.<br> |
|
This model was created by adding and subtracting the weights of the [llava-v1.5-7b](https://huggingface.co/liuhaotian/llava-v1.5-7b), [Llama-2-7b-hf](https://huggingface.co/meta-llama/Llama-2-7b-hf), and [ELYZA-japanese-Llama-2-7b](https://huggingface.co/elyza/ELYZA-japanese-Llama-2-7b) models using the Chat Vector method as follows. |
|
``` |
|
ELYZA-japanese-Llama-2-7b + (llava-v1.5-7b - Llama-2-7b-hf) |
|
``` |
|
|
|
Chat-Vector-LLaVA-v1.5-7b-JAは、入力画像について日本語で会話できるvision-language modelです。<br> |
|
このモデルはChat Vectorの手法で[llava-v1.5-7b](https://huggingface.co/liuhaotian/llava-v1.5-7b)と[Llama-2-7b-hf](https://huggingface.co/meta-llama/Llama-2-7b-hf)と[ELYZA-japanese-Llama-2-7b](https://huggingface.co/elyza/ELYZA-japanese-Llama-2-7b)のモデルの重みを以下の通り加減算することで作成しました。 |
|
``` |
|
ELYZA-japanese-Llama-2-7b + (llava-v1.5-7b - Llama-2-7b-hf) |
|
``` |

## How to use the model |
|
> [!WARNING] |
|
> The code for the demo worked with 4.34.1 of transformers, but did not work properly with 4.37.2. We have not tested the code in between versions or in the latest version.<br> |
|
> デモ用のコードはtransformersの4.34.1では動作しましたが、4.37.2では正常に動作しませんでした。間のバージョンや最新のバージョンでは動作確認していません。 |
