Introduction

InternLM2.5 builds on the InternLM2 architecture by harnessing a wealth of synthetic data for improved performance. It employs a capability flywheel mechanism that allows the model to continuously self-improve, leading to advanced reasoning capabilities over its predecessor.

Installation

To get started, you need to install the Transformers library if you haven’t already. Use pip to install:

pip install transformers torch

Using InternLM2.5

Now, let’s dive into how to use InternLM2.5 for text generation. Consider this analogy: think of the model as a chef who needs ingredients (inputs) to create a dish (output). Below is the step-by-step process to implement this.

Step 1: Import Required Libraries

First, you need to import the necessary components:

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

Step 2: Load the Model and Tokenizer

Next, you will load the tokenizer and the model:

tokenizer = AutoTokenizer.from_pretrained(
    "internlm/internlm2_5-1_8b",
    trust_remote_code=True
)
model = AutoModelForCausalLM.from_pretrained(
    "internlm/internlm2_5-1_8b",
    torch_dtype=torch.float16,
    trust_remote_code=True
).cuda()
model = model.eval()

Step 3: Prepare Input

Now, think of the next step as preparing your ingredients. You’ll prepare your input text for the chef (model) to work on:

inputs = tokenizer(["A beautiful flower"], return_tensors="pt")
for k, v in inputs.items():
    inputs[k] = v.cuda()

Step 4: Generate Text

Finally, it’s time for the chef to do his magic:

gen_kwargs = {
    "max_length": 128,
    "top_p": 0.8,
    "temperature": 0.8,
    "do_sample": True,
    "repetition_penalty": 1.0
}
output = model.generate(**inputs, **gen_kwargs)
output = tokenizer.decode(output[0].tolist(), skip_special_tokens=True)
print(output)

Troubleshooting

If you encounter issues while using InternLM2.5, here are a few troubleshooting tips:

• Out of Memory (OOM) Errors: If the model fails to load due to memory constraints, consider changing the precision by using torch_dtype=torch.float32 instead of torch.float16.
• Unexpected Outputs: Due to the probabilistic nature of the model, occasionally it might generate undesired or unexpected outputs. Always review outputs for content propriety.
• Model Loading Issues: Ensure that your library and model paths are correct and that you’ve installed the required dependencies.
