Thanks to the original coder. I've added a few options to improve captioning for EveryDream2 and limit the minigpt4 hallucinations.

At the defailt beams of 8, each caption takes about 20 to 25 seconds to generate.

On the captioning side, the code breaks the caption into sentences and limits the number of sentences to three. Through my experimentation, I've found that the third sentece usually describes the background of image. You may want to change line 174, to sentences = [s.strip() + '.' for s in sentences[:2]], if you prefer 2 sentence captions.

The code also attempts to remove sentence fragments from the caption, but not always succeeeds.

The code also attempts to remove phrases in the caption that aren't descriptive, e.g. "The image shows" and "looking directly at the camera," etc.

There is an option to specify the identity of the person in a folder, with --name "John Smith" or whatever name you choose. The name of the person will be substituted for generic nouns like "woman" or "man."

On the image side, the code checks if the image contains a transparency, and if it does, removes it and saves the image.

You can also specify a target size for the images. The default is 768 on the smaller side. If the smaller side is less than 768, it will be resized, keeping the aspect ratio, and saved. If the smaller side is greater than or equal to 768, the image will be unchanged.

Welcome to the MiniGPT-4 Batch repo! This repository provides an implementation of MiniGPT-4 to mass caption Stable Diffusion images. It utilizes llama weights that are downloaded automatically if not already present. Please note that this implementation currently works only on Linux systems and runs only on high end machines (not the free colab).

Windows Installation Instructions

To install and run MiniGPT-4 Batch on Windows, please follow these steps:

1. Run the Setup.bat script:

   Setup.bat
   

2. Check your /images and /mycaptions folders. In the /images folder, one sample image is provided; feel free to delete it.

3. If you're just testing it out, simply execute the run.bat script.

   OR

4. If you want to run the script manually, you need to:

   a. Activate the virtual environment:

   .\venv\Scripts\activate.bat
   

   b. Run the app.py script with the desired options:

   python app.py --image-folder ./images --beam-search-numbers 2
   

   NEW: We're testing to combine WD tags with minigpt4-batch. If you want to include WD tags along with minigpt4 captions, consider running backup_app.py. In backup_app.py WD tagging is mandatory, working to make that optional!

   python backup_app.py --image-folder ./images --beam-search-numbers 2 --model-dir models/wd14_tagger --undesired-tags '1girl,1boy,solo'
   

Now you're all set to use MiniGPT-4 Batch on Windows!

Getting Started (LINUX)

If you're installing MiniGPT-4 Batch for the first time, please follow these steps:

1. Clone the GitHub repository:

   git clone https://github.com/pipinstallyp/minigpt4-batch
   

Change directory to minigp4-batch

 cd minigpt4-batch

2. Download the necessary files:

   wget https://huggingface.co/ckpt/minigpt4/resolve/main/minigpt4.pth -O ./checkpoint.pth
   wget https://huggingface.co/ckpt/minigpt4/resolve/main/blip2_pretrained_flant5xxl.pth -O ./blip2_pretrained_flant5xxl.pth
   

   For 7b, then just use this:

   wget https://huggingface.co/ckpt/minigpt4-7B/resolve/main/prerained_minigpt4_7b.pth -O ./checkpoint.pth
   wget https://huggingface.co/ckpt/minigpt4/resolve/main/blip2_pretrained_flant5xxl.pth -O ./blip2_pretrained_flant5xxl.pth
   

To get this right you'd need to replace ./minigpt4/checkpoint.pth with directory your minigpt4 directory + checkpoint.pth, for example.

3. Install the required packages:

   pip install cmake
   pip install lit
   pip install -q salesforce-lavis
   pip install -q bitsandbytes
   pip install -q accelerate
   pip install -q git+https://github.com/huggingface/transformers.git -U
   

4. Now, you can run the script:

   python app.py --image-folder path_to_image_folder --beam-search-numbers value
   

   If you want to test llama 7b then use this:

   python app.py --image-folder path_to_image_folder --beam-search-numbers 2 --model llama7b
   

In your repository directory you can make two folders namely

images  
mycaptions

in this case your path_to_image_folder = images

Features

1. Shows timestamp to process each caption
2. Use --save-in-imgfolder to save captions in your images folder instead.
3. One click setup (setup.bat) for windows.

To-Do List

• Make it work on Windows
• Implement for MiniGPT-4 7B
• Include inputs from Segment Anything
• DOCKER SUPPORT COMING TO YAYYYY

Acknowledgment

A huge thank you to Camenduru for developing the awesome MiniGPT-4 Colab, which has served as the foundation for most of this work. Huge thanks to rafraf for making the features what they are. This project is primarily aimed at helping people train Stable Diffusion models to mass caption their images.
