How to install and use DeepSeek R-1 locally

What is DeepSeek R-1?

DeepSeek R-1 is an open-source AI language model developed by a Chinese AI firm, DeepSeek. It’s based on a large foundational model (DeepSeek-V3) and refined using supervised fine-tuning. It’s known for its reasoning capabilities and offers free access, which makes it a popular option for AI enthusiasts and developers.

Running it locally ensures better data privacy since you avoid sending your data to external servers.

Step 1: Prerequisites

Before installing DeepSeek R-1, make sure your system meets the following requirements:

Hardware Requirements

  • GPU: A capable NVIDIA GPU with at least 12GB of VRAM (for medium-sized models) or 24GB+ (for larger models).
  • RAM: At least 16GB of system memory (32GB recommended).
  • Disk Space: Around 20-50GB of free space for the model weights and dependencies.

Software Requirements

  • Operating System: Linux or Windows (Linux recommended for better compatibility with AI libraries).
  • Python: Version 3.8 or higher.
  • CUDA and cuDNN: Installed to leverage GPU acceleration.
  • Git: To clone the repository.

Step 2: Download DeepSeek R-1

  1. Clone the Repository DeepSeek R-1’s open-source codebase is typically hosted on platforms like GitHub. Use the following command to clone the repository (replace <repository-url> with the actual URL):

git clone <repository-url>
cd deepseek-r1        

2. Download the Model Weights Visit the official website or repository to download the pre-trained model weights. These are usually provided as .bin or .pt files. Place the downloaded weights in the appropriate folder (e.g., models/).

Step 3: Install Dependencies

  1. Create a Virtual Environment (optional but recommended):

python -m venv deepseek_env
source deepseek_env/bin/activate  # On Windows: deepseek_env\Scripts\activate        

2. Install Required Libraries: Use pip to install dependencies listed in the requirements.txt file:

pip install -r requirements.txt        

3. Ensure CUDA is Configured: Verify that PyTorch is using your GPU by running:

import torch
print(torch.cuda.is_available())        

Step 4: Running DeepSeek R-1 Locally

  1. Load the Model: Use a Python script to load the model and weights. For example:

from transformers import AutoModelForCausalLM, AutoTokenizer

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained("path_to_weights")

# Load model
model = AutoModelForCausalLM.from_pretrained("path_to_weights")

# Verify the setup
text = "What is DeepSeek R-1?"
inputs = tokenizer(text, return_tensors="pt")
outputs = model.generate(**inputs)
print(tokenizer.decode(outputs[0]))        

2. Run the Model: Execute the script to interact with DeepSeek R-1. You can fine-tune the script for different tasks like question-answering, summarization, or creative text generation.

3. Optional: Use a Web Interface Set up a simple web-based interface (e.g., using Gradio or Streamlit) to interact with the model:

import gradio as gr

def reply(prompt):
    inputs = tokenizer(prompt, return_tensors="pt")
    outputs = model.generate(**inputs)
    return tokenizer.decode(outputs[0])

interface = gr.Interface(fn=reply, inputs="text", outputs="text")
interface.launch()        

Step 5: Fine-Tune (Optional)

If you want to fine-tune DeepSeek R-1 on your own dataset:

  1. Prepare a dataset in a format like JSON or CSV.
  2. Use libraries like transformers to fine-tune the model:

from transformers import Trainer, TrainingArguments

training_args = TrainingArguments(
    output_dir="./results",
    num_train_epochs=3,
    per_device_train_batch_size=8,
    save_steps=10,
    save_total_limit=2,
)

trainer = Trainer(
    model=model,
    args=training_args,
    train_dataset=train_dataset,
)

trainer.train()        

Step 6: Use Cases

Once DeepSeek R-1 is running on your local machine, you can use it for:

  • Text generation
  • Summarization
  • Question answering
  • Creative writing
  • Chatbot development

Troubleshooting

  1. Model Loading Errors: Ensure the paths to the weights and tokenizer are correct.
  2. Memory Issues: If your GPU runs out of memory, consider using a smaller model variant or running the model in CPU mode (though slower):

model = AutoModelForCausalLM.from_pretrained("path_to_weights", device_map="cpu")        

3. Dependency Issues: Update your Python and library versions.
