Quick Start

Let’s dive into the code to run the Mini-InternVL-Chat-2B-V1-5 with ease. Below are various methods of model loading and inference processes:

Model Loading

There are different options available for loading the model based on your GPU configuration:

16-bit (bf16 & fp16)

python
import torch
from transformers import AutoTokenizer, AutoModel

path = "OpenGVLab/Mini-InternVL-Chat-2B-V1-5"
model = AutoModel.from_pretrained(
    path,
    torch_dtype=torch.bfloat16,
    low_cpu_mem_usage=True,
    trust_remote_code=True
).eval().cuda()

8-bit Quantization

python
import torch
from transformers import AutoTokenizer, AutoModel

path = "OpenGVLab/Mini-InternVL-Chat-2B-V1-5"
model = AutoModel.from_pretrained(
    path,
    torch_dtype=torch.bfloat16,
    load_in_8bit=True,
    low_cpu_mem_usage=True,
    trust_remote_code=True
).eval()

4-bit Quantization

python
import torch
from transformers import AutoTokenizer, AutoModel

path = "OpenGVLab/Mini-InternVL-Chat-2B-V1-5"
model = AutoModel.from_pretrained(
    path,
    torch_dtype=torch.bfloat16,
    load_in_4bit=True,
    low_cpu_mem_usage=True,
    trust_remote_code=True
).eval()

Understanding the Code: An Analogy

Think of the process of loading this model as cooking a meal. The ingredients are your model configurations (like the GPU type or quantization method), and the cooking instructions are the code snippets you followed. Each snippet is a step in preparing your dish, ensuring it turns out well — just as you would ensure your model runs correctly!

Troubleshooting

Should you encounter any errors or unusual behavior, here are a few troubleshooting tips:

• Check your GPU Compatibility: Ensure that your hardware meets the model requirements.
• Version Conflicts: Ensure you are using transformers==4.37.2 for compatibility.
• Memory Issues: If you experience memory errors, consider using the load_in_8bit or load_in_4bit options for reduced memory usage.
• Unexpected Outputs: The model may exhibit biases or generate inappropriate content. Review the inputs and examine training data.
