Solution to Python Installation Issues

You can try the following methods:

Run this command in your terminal: sudo xcodebuild -license and accept the xcode license.
Run this command in your terminal: xcode-select --install to install developer tools.
Make sure your internet connection is working properly.
Ensure that the version of /usr/bin/python3 is not python3.12, as PyTorch does not support that version. Also, make sure it is at least >= python3.8, as PyTorch 2.0 explicitly states that it does not support versions below 3.7.
Upgrade your macOS system. The MPS backend requires macOS 12.3+.

Solution to Python Dependency Installation Failures

If you have the correct version of Python 3 and still encounter installation failures at this step, it is likely due to a network issue. Close the software and retry a few times.

How to Completely Uninstall?

Remove DrawingPics from the applications using any method, and then delete the user data directory of DrawingPics (do not delete the wrong directory):

$ rm -r ~/Library/Application\ Support/DrawingPics/

This will completely remove it, and you can email me to deactivate your license.

Unable to Open the Canvas for Drawing?

Go to User Preference -> Clear Image Cache and click.

Click the Start button, and the software should handle everything for you. If it's your first time using it, you need to wait for the download of approximately 4GB. You can see the download progress bar below the Start button.

If you want to manually download the model files, click the link below: https://t.drawing.pics/redirect?download_filename=drawingpics_models.zip

Make sure the downloaded file is in the Downloads directory and named drawingpics_models.zip. Then, reopen the application and click the Start button. We will search for the model file in the download directory.

What is the Difference between Quick Drawing and Sketching?

Quick Drawing

You can draw freely with different colors, and the generated images will have randomness. It uses the SD1.5 image generation technology as its foundation.

Sketching

It only accepts two colors: black and white. Other colors are treated as black. It generates images precisely according to the lines you draw. It uses a technology similar to ControlNet, which accurately reflects the content you draw.

What Do the Parameters in the Advanced Panel Mean?

Models

SD Fine-tuning models are trained from datasets. The models in the community are trained based on specific requirements, such as real people, anime, objects, etc. You can find model files in the Civitai community and place them in the models folder to use them. If you don't know how to do it, you can use the dreamshaper_8.safetensors model I provided.

Loras

LoRA (Low-Rank Adaptation) is also a technique for fine-tuning models. However, the final size of the model is only 2-200MB, and the training process is easy. The performance is slightly inferior and needs to be used in combination with the base model.

Steps

DrawingPics uses LCM LoRA for acceleration, so it is usually set to 4-5 steps, which is equivalent to setting 30 steps in the normal setting.

GScale

Guidance scale determines the relevance between your prompt and the generated image. The lower the value, the more divergent the model becomes.

Strength

Denoising strength determines the relevance between your original image and the generated image. The lower the value, the more the generated image resembles your original image. A value of 0 means it is identical to your original image. A value of 1 means they are completely unrelated.
