BlueLM is a large-scale open-source language model developed by the vivo AI Lab, and it provides an enhanced experience in natural language processing tasks. This blog will guide you through the installation, inference, and possible troubleshooting techniques to get the most out of BlueLM.

Introduction to BlueLM

BlueLM has various features that set it apart from other language models:

• Data Training: Trained on an extensive dataset of 2.6 trillion tokens, primarily in Chinese and English.
• Performance: It achieves strong results in benchmarks like C-Eval and CMMLU.
• Extended Context: BlueLM-7B-Base and BlueLM-7B-Chat now support a context length of 32K tokens, enhancing their understanding capability.
• Model Licensing: The model supports academic research and commercial use under the Apache-2.0 license.

Getting Started with BlueLM

To start using BlueLM, you need to install the required libraries and load the model. Let’s illustrate this with an analogy:

Imagine you’re a chef preparing a gourmet dish. You first need the right ingredients and tools (libraries and code). After gathering everything, you carefully follow the recipe (code instructions) to create your dish (model deployment).

Installation

To get started, first install the transformers library:

pip install transformers

Inference and Deployment

Here’s the code snippet you will use for deploying the BlueLM model. Pay attention to how each step serves a specific purpose, just like following a recipe:

python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained('vivo-ai/BlueLM-7B-Chat-32K-AWQ', trust_remote_code=True, use_fast=False)

model = AutoModelForCausalLM.from_pretrained(
    'vivo-ai/BlueLM-7B-Chat-32K-AWQ',
    device_map='cuda:0',
    torch_dtype=torch.float16,
    trust_remote_code=True,
    low_cpu_mem_usage=True,
    use_cache=False
)

model = model.eval()
inputs = tokenizer(['[Human]: 1000 [AI]:'], return_tensors='pt')
inputs = inputs.to('cuda:0')
pred = model.generate(**inputs, max_new_tokens=2048, repetition_penalty=1.1)

print(tokenizer.decode(pred.cpu()[0], skip_special_tokens=True))

Troubleshooting

If you encounter issues during the installation or using BlueLM, consider these troubleshooting tips:

• Ensure that your Python environment has sufficient memory and that the correct version of the transformers library is installed.
• Check if your graphics card drivers are up to date if you’re using GPU for the model.
• Verify that the URLs and parameters used in the code are correct and properly formatted.
