Complete Guide to Visual ChatGPT

In this post, we will talk about how to run Visual ChatGPT in Python with Google Colab. ChatGPT has garnered huge popularity recently due to its capability of human style response. As of now, it only provides responses in text format, which means it cannot process, generate or edit images. Microsoft recently released a solution for the same to handle images. Now you can ask ChatGPT to generate or edit the image for you.

Benefits of Visual ChatGPT

It has a variety of benefits ranging from generating images to advanced editing capabilities of images

  • Generate image from user input text
  • Remove object from the photo
  • Replace one object with the other object from the photo
  • It can explain what is inside in the photo
  • Make the image look like a painting
  • Edge detection
  • Line detection
  • Hed detection
  • Generate image condition on soft Hed boundary image
  • Segmentation on image
  • Generate image condition on segmentations

How Visual ChatGPT works

It integrates different Visual Foundation Models with ChatGPT. In simple terms, Visual Foundation Models are advanced algorithms for editing images. With the use of these visual foundation models, it results to ChatGPT can also handle user requests of generating and editing images. It is not just capable of understanding instructions (search query) of user, it also has feedback loop of modifying and improving the output based on feedback.

The source of the image below is the official Microsoft Visual ChatGPT Github repository.

Steps to run Visual ChatGPT

Since this is a memory-intensive task which requires high computation and GPU, we are using Google Colab. Colab provides free access to GPU resources, solves the problem of purchasing expensive hardware. It is available from anywhere with just an internet connection, also allows managing version control for projects.

Check out my Google Colab notebook.

Step 1 : Create an environment with Python 3.8
import sys
sys.path.append("/usr/local/lib/python3.8/site-packages")
Step 2 : Clone Github Repo
I forked github repository of Visual ChatGPT and made changes to work for Colab. Those who does not know Forking a GitHub repository, it simply means allowing to make changes to a project without affecting the original code. In colab, we are creating a copy of my repository.
!git clone https://github.com/deepanshu88/visual-chatgpt.git
Cloning into 'visual-chatgpt'...
remote: Enumerating objects: 129, done.
remote: Counting objects: 100% (90/90), done.
remote: Compressing objects: 100% (65/65), done.

The folder structure of this repos is as follows.
├── assets
│   ├── demo.gif
│   ├── demo_short.gif
│   └── figure.jpg
├── LICENSE.md
├── README.md
├── requirements.txt
└── visual_chatgpt.py
Step 3 : Setting working directory
Setting working directory to the copy of github repos we created in the previous step.
%cd visual-chatgpt
Step 4 : Installing the required packages
The packages we need to install are mentioned in the requirement.txt file.
!curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
!python3.8 get-pip.py
!python3.8 -m pip install -r requirements.txt
Step 5 : Enter API Key

To get started with the OpenAI API, go to the website platform.openai.com and sign up for an account using your Google or Microsoft email address. The crucial step after signing up is to obtain a secret API key that will allow you to access the API.

%env OPENAI_API_KEY=sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Step 6 : Start Visual ChatGPT
!python3.8 ./visual_chatgpt.py --load Text2Image_cuda:0,ImageCaptioning_cuda:0,VisualQuestionAnswering_cuda:0,Image2Canny_cpu,Image2Line_cpu,Image2Pose_cpu,Image2Depth_cpu,CannyText2Image_cuda:0,InstructPix2Pix_cuda:0,Image2Seg_cuda:0

Visual Foundation Models : Memory Usage

I am using the below 10 models only due to insufficient GPU resources in Colab. In other words, I had to restrict to these 10 models only as I am using free GPU offered by Colab, not the paid premium GPUs.

  1. Text2Image
  2. ImageCaptioning
  3. CannyText2Image
  4. InstructPix2Pix
  5. VisualQuestionAnswering
  6. Image2Canny
  7. Image2Line
  8. Image2Pose
  9. Image2Depth
  10. Image2Seg

There are more than 20 models available for use. See the list below. You can use them as per your requirement.

How to fix common issues

RuntimeError: CUDA error: invalid device ordinal
Solution : Replace all cuda:\d with cuda:0 in visual_chatgpt.py file. This error occurs because you don't have enough graphic card.
OutOfMemoryError: CUDA out of memory
Solution : This error occurs because you don't have enough GPU resources available to run visual foundation models. To fix this, you need to ignore some of the models which you don't need in download.sh and visual_chatgpt.py files. Under visual_chatgpt.py file, modify self.tools section of the code to include/exclude some visual foundation models.
opencv-contrib-python==4.3.0.36 Has been Yanked
Solution : Use this version opencv-contrib-python==4.5.1.48 in requirement.txt file.

How is Visual ChatGPT different from Image Editing Software?

Visual ChatGPT understands questions of user and then create or edit image accordingly. Whereas Image Editing softwares don't have capability to comprehend user input text. Visual ChatGPT also performs further modification as per feedback from user. Visual ChatGPT has advanced editing capabilities like removing object from the image or replace it with the other object. It can also explain in simple English what is contained within the photo.
