How to run DeepSeek Janus Pro on Google Colab

The DeepDeek’s Janus series repository on GitHub provides a demo using Gradio for anyone to try. We can set this up on a Google Colab notebook as shown below.

1. Open a new Google Colab notebook.

2. In the first cell, let’s clone the Github repo.

   1. !git clone https://github.com/deepseek-ai/Janus.git

3. In the second cell, install package in editable mode and also install Gradio.

   1. %cd Janus

      !pip install -e .

      !pip install gradio

4. You can edit the demo/app_januspro.py file to use desirable model for testing. By default it uses “deepseek-ai/Janus-Pro-7B” model. The list of available models can be found here - https://github.com/deepseek-ai/Janus?tab=readme-ov-file#huggingface

5. In the third cell, run the demo.

   1. !python3 demo/app_januspro.py

6. It will create a gradio.live link that you can click to view the Gradio interface where you can play with the “Multimodal Understanding” and “Text-to-Image Generation” features of the Janus Pro model.

   1. 

   2. The Gradio interface should look like this.
