# InternVL3_5-2B

This version of InternVL3_5-2B has been converted to run on the Axera NPU using **w8a16** quantization.

This model has been optimized with the following LoRA: 

Compatible with Pulsar2 version: 5.1-patch1.

Please note that the context of the model is 2k and the maximum prefill length is 1k.

Run the following command on the Axera board to start a chat conversation:

```sh
$ python3 infer_axmodel.py --hf_model internvl3-5_tokenizer/ --axmodel_path internvl3-5_axmodel/ --question "请计算函数[y=2x^2+2]的导数, 并提供 markdown 格式的推理过程"
```

output:

answer >> 函数 \( y = 2x^2 + 2 \) 的导数可以通过求导法则来计算。首先，我们对函数中的每一项分别求导：

1. 对于 \( 2x^2 \)，使用幂法则求导：
   \[
   \frac{d}{dx}(2x^2) = 2 \cdot 2x = 4x
   \]

2. 对于常数项 \( 2 \)，其导数为 0，因为常数的导数为 0。

将这两部分的结果相加，得到函数 \( y \) 的导数：
\[
y' = 4x
\]

因此，函数 \( y = 2x^2 + 2 \) 的导数为 \( y' = 4x \)。
```

answer >> 这是一张红熊猫的照片。红熊猫是一种红棕色的哺乳动物，通常生活在亚洲的森林中。它们以捕食昆虫和小型无脊椎动物为生。图片中，红熊猫正坐在一个木制的平台上，背景是绿色的树木和植被，显得非常自然和生动。红熊猫的表情看起来很友好，似乎在观察或等待什么。
