Ryan Murdock has done it again, combining OpenAI's CLIP and the generator from a BigGAN! This repository wraps up his work so it is easily accessible to anyone who owns a GPU.
You will be able to have the GAN dream up images using natural language with a one-line command in the terminal.
User-made notebook with bugfixes and added features, like google drive integration
$ pip install big-sleep
$ dream "a pyramid made of ice"
Images will be saved to wherever the command is invoked
You can invoke this in code with
from big_sleep import Imagine
dream = Imagine(
text = "fire in the sky",
lr = 5e-2,
save_every = 25,
save_progress = True
)
dream()
You can now train more than one phrase using the delimiter "|"
In this example we train on three phrases:
an armchair in the form of pikachu
an armchair imitating pikachu
abstract
from big_sleep import Imagine
dream = Imagine(
text = "an armchair in the form of pikachu|an armchair imitating pikachu|abstract",
lr = 5e-2,
save_every = 25,
save_progress = True
)
dream()
In this example we train on the three phrases from before,
and penalize the phrases:
blur
zoom
from big_sleep import Imagine
dream = Imagine( text = "an armchair in the form of pikachu|an armchair imitating pikachu|abstract", text_min = "blur|zoom", ) dream()
You can also set a new text by using the `.set_text(<str>)` command
```python
dream.set_text("a quiet pond underneath the midnight moon")
And reset the latents with .reset()
dream.reset()
To save the progression of images during training, you simply have to supply the --save-progress
flag
$ dream "a bowl of apples next to the fireplace" --save-progress --save-every 100
Due to the class conditioned nature of the GAN, Big Sleep often steers off the manifold into noise. You can use a flag to save the best high scoring image (per CLIP critic) to {filepath}.best.png
in your folder.
$ dream "a room with a view of the ocean" --save-best
If you have enough memory, you can also try using a bigger vision model released by OpenAI for improved generations.
$ dream "storm clouds rolling in over a white barnyard" --larger-model
You can set the number of classes that you wish to restrict Big Sleep to use for the Big GAN with the --max-classes
flag as follows (ex. 15 classes). This may lead to extra stability during training, at the cost of lost expressivity.
$ dream 'a single flower in a withered field' --max-classes 15
