The format should be broken down like this: {Art Style}, {Subject}, {Details}, {Color}\n The art style should be determined by the overall impression of the song. If it is sad, then something like La Douleur should be used. If it is happy, perhaps a vibrant street art style.\nThe Subject should be determined by who the song is about. If the song is about a couple trying to escape the city, then the subject should be a couple.\nThe Details should be determined by descriptive words used in the song. If they mention empty bottles, then add empty bottles to the prompt.\nThe color should be determined by the mood of the song. If the mood is a happy one, use bright colors.\nHere is an example:\n{A dreamlike and ethereal art style}, {a couple standing on a cliffside embracing, overlooking a surreal and beautiful landscape}, {sunset, grassy, soft wind}, {soft pastels, with hints of warm oranges and pinks}",

# Do I need to worry about this:
# To preserve the default model's safety features
# through the fine-tuning process, fine-tuning training data is passed through
# our Moderation API and a GPT-4 powered moderation system to detect unsafe
# training data that conflict with our safety standards.
def backlog(): ...
# TODO / backlog
# Is fine-tuning a solution to my use case?
# We recommend starting with 50 well-crafted demonstrations and seeing if the
# model shows signs of improvement after fine-tuning. In some cases that may be
# sufficient, but even if the model is not yet production quality, clear
# improvements are a good sign that providing more data will continue to improve
# the model. No improvement suggests that you may need to rethink how to set up
# the task for the model or restructure the data before scaling beyond a limited
# example set.
# So, hand-pick some key converstaion examples from the dataset, and see if I can detect improvement subjectively
# The text exports from WhatsApp lose the references to the message being replied to.
# Lookup: is there any way to preserve that in the export (any other export formats?)
# So, the context of the previous thread is broken without any replies being linked to the replied-to message.
# I could just use timestamps to demarcate a new context/conversation, eg 60+ mins apart
# Or keep the thread/conversation "open" if the previous one ended with/contains a '?'
# Count what my context length (median) is with those assumptions (and assume 4 chars-per-token). Should be < 8K (~32K chars)
# Group conversation threads into a list of messages, and start a new set of messages when it's a new thread.
# (That might also make it easier to split the list of threads/conversations into training/test sets)
# You could just have one list of messages, but I feel like it makes sense to break these into time-blocked conversation threads, since the messages in a thread are part of the same context.
# Each training example is limited to 4096 tokens (I guess that's all the messages in the thread)
# I'm assuming that I use the 'user' and 'assistant' roles for the two people in the conversation ...

"""Optimal Combination Reconciliation Class.
The Empirical Risk Minimization reconciliation strategy relaxes the unbiasedness assumptions from
previous reconciliation methods like MinT and optimizes square errors between the reconciled predictions
and the validation data to obtain an optimal reconciliation matrix P.
The exact solution for $\mathbf{P}$ (`method='closed'`) follows the expression:
$$\mathbf{P}^{*} = \\left(\mathbf{S}^{\intercal}\mathbf{S}\\right)^{-1}\mathbf{Y}^{\intercal}\hat{\mathbf{Y}}\\left(\hat{\mathbf{Y}}\hat{\mathbf{Y}}\\right)^{-1}$$
The alternative Lasso regularized $\mathbf{P}$ solution (`method='reg_bu'`) is useful when the observations
of validation data is limited or the exact solution has low numerical stability.
$$\mathbf{P}^{*} = \\text{argmin}_{\mathbf{P}} ||\mathbf{Y}-\mathbf{S} \mathbf{P} \hat{Y} ||^{2}_{2} + \lambda ||\mathbf{P}-\mathbf{P}_{\\text{BU}}||_{1}$$

prompt_2 (`str` or `List[str]`, *optional*):
The prompt or prompts to be sent to the `tokenizer_2` and `text_encoder_2`. If not defined, `prompt` is
used in both text-encoders
height (`int`, *optional*, defaults to self.unet.config.sample_size * self.vae_scale_factor):
The height in pixels of the generated image.
width (`int`, *optional*, defaults to self.unet.config.sample_size * self.vae_scale_factor):
The width in pixels of the generated image.
num_inference_steps (`int`, *optional*, defaults to 50):
The number of denoising steps. More denoising steps usually lead to a higher quality image at the
expense of slower inference.
denoising_end (`float`, *optional*):
When specified, determines the fraction (between 0.0 and 1.0) of the total denoising process to be
completed before it is intentionally prematurely terminated. As a result, the returned sample will
still retain a substantial amount of noise as determined by the discrete timesteps selected by the
scheduler. The denoising_end parameter should ideally be utilized when this pipeline forms a part of a
"Mixture of Denoisers" multi-pipeline setup, as elaborated in [**Refining the Image
Output**](https://huggingface.co/docs/diffusers/api/pipelines/stable_diffusion/stable_diffusion_xl#refining-the-image-output)
guidance_scale (`float`, *optional*, defaults to 5.0):
Guidance scale as defined in [Classifier-Free Diffusion Guidance](https://arxiv.org/abs/2207.12598).
`guidance_scale` is defined as `w` of equation 2. of [Imagen
Paper](https://arxiv.org/pdf/2205.11487.pdf). Guidance scale is enabled by setting `guidance_scale >
1`. Higher guidance scale encourages to generate images that are closely linked to the text `prompt`,
usually at the expense of lower image quality.
negative_prompt (`str` or `List[str]`, *optional*):
The prompt or prompts not to guide the image generation. If not defined, one has to pass
`negative_prompt_embeds` instead. Ignored when not using guidance (i.e., ignored if `guidance_scale` is
less than `1`).
negative_prompt_2 (`str` or `List[str]`, *optional*):
The prompt or prompts not to guide the image generation to be sent to `tokenizer_2` and
`text_encoder_2`. If not defined, `negative_prompt` is used in both text-encoders
num_images_per_prompt (`int`, *optional*, defaults to 1):
The number of images to generate per prompt.
eta (`float`, *optional*, defaults to 0.0):
Corresponds to parameter eta (η) in the DDIM paper: https://arxiv.org/abs/2010.02502. Only applies to
[`schedulers.DDIMScheduler`], will be ignored for others.
generator (`torch.Generator` or `List[torch.Generator]`, *optional*):
One or a list of [torch generator(s)](https://pytorch.org/docs/stable/generated/torch.Generator.html)
to make generation deterministic.
latents (`torch.FloatTensor`, *optional*):
Pre-generated noisy latents, sampled from a Gaussian distribution, to be used as inputs for image
generation. Can be used to tweak the same generation with different prompts. If not provided, a latents
tensor will ge generated by sampling using the supplied random `generator`.
prompt_embeds (`torch.FloatTensor`, *optional*):
Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not
provided, text embeddings will be generated from `prompt` input argument.
negative_prompt_embeds (`torch.FloatTensor`, *optional*):
Pre-generated negative text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt
weighting. If not provided, negative_prompt_embeds will be generated from `negative_prompt` input
argument.
pooled_prompt_embeds (`torch.FloatTensor`, *optional*):
Pre-generated pooled text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting.
If not provided, pooled text embeddings will be generated from `prompt` input argument.
negative_pooled_prompt_embeds (`torch.FloatTensor`, *optional*):
Pre-generated negative pooled text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt
weighting. If not provided, pooled negative_prompt_embeds will be generated from `negative_prompt`
input argument.
output_type (`str`, *optional*, defaults to `"pil"`):
The output format of the generate image. Choose between
[PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`.
return_dict (`bool`, *optional*, defaults to `True`):
Whether or not to return a [`~pipelines.stable_diffusion_xl.StableDiffusionXLPipelineOutput`] instead
of a plain tuple.
callback (`Callable`, *optional*):
A function that will be called every `callback_steps` steps during inference. The function will be
called with the following arguments: `callback(step: int, timestep: int, latents: torch.FloatTensor)`.
callback_steps (`int`, *optional*, defaults to 1):
The frequency at which the `callback` function will be called. If not specified, the callback will be
called at every step.
cross_attention_kwargs (`dict`, *optional*):
A kwargs dictionary that if specified is passed along to the `AttentionProcessor` as defined under
`self.processor` in
[diffusers.models.attention_processor](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py).
guidance_rescale (`float`, *optional*, defaults to 0.7):
Guidance rescale factor proposed by [Common Diffusion Noise Schedules and Sample Steps are
Flawed](https://arxiv.org/pdf/2305.08891.pdf) `guidance_scale` is defined as `φ` in equation 16. of
[Common Diffusion Noise Schedules and Sample Steps are Flawed](https://arxiv.org/pdf/2305.08891.pdf).
Guidance rescale factor should fix overexposure when using zero terminal SNR.
original_size (`Tuple[int]`, *optional*, defaults to (1024, 1024)):
If `original_size` is not the same as `target_size` the image will appear to be down- or upsampled.
`original_size` defaults to `(width, height)` if not specified. Part of SDXL's micro-conditioning as
explained in section 2.2 of
[https://huggingface.co/papers/2307.01952](https://huggingface.co/papers/2307.01952).
crops_coords_top_left (`Tuple[int]`, *optional*, defaults to (0, 0)):
`crops_coords_top_left` can be used to generate an image that appears to be "cropped" from the position
`crops_coords_top_left` downwards. Favorable, well-centered images are usually achieved by setting
`crops_coords_top_left` to (0, 0). Part of SDXL's micro-conditioning as explained in section 2.2 of
[https://huggingface.co/papers/2307.01952](https://huggingface.co/papers/2307.01952).
target_size (`Tuple[int]`, *optional*, defaults to (1024, 1024)):
For most cases, `target_size` should be set to the desired height and width of the generated image. If
not specified it will default to `(width, height)`. Part of SDXL's micro-conditioning as explained in
section 2.2 of [https://huggingface.co/papers/2307.01952](https://huggingface.co/papers/2307.01952).
Examples:
Returns:
[`~pipelines.stable_diffusion_xl.StableDiffusionXLPipelineOutput`] or `tuple`:
[`~pipelines.stable_diffusion_xl.StableDiffusionXLPipelineOutput`] if `return_dict` is True, otherwise a
`tuple`. When returning a tuple, the first element is a list with the generated images.

WebUI
=====
The :class:`WebUI` is used to enable an html interface where the user can
browse the devices content via web browser. By default, the WebUI interface
is disabled and could be enabled from config file or by config dictionary when
initializing :class:`~coherence.base.Coherence`
.. versionchanged:: 0.8.2
.. note:: Be aware that the browser should support Web Sockets and js enabled.
All modern browsers should have this features integrated (tested with
firefox and google chrome).
.. warning:: Don't create your web server into port 9000. This is reserved for
the js WebSocket.

FSStore - filesystem media server
---------------------------------
FSStore exposes media files found in the directory trees defined by
the 'content' configuration entry.
The first ".jpg" or ".png" file found inside a media directory is
served as a cover image.
The plugin is configured with::
<plugin active="yes">
<!-- The plugin identifier, mandatory -->
<backend>FSStore</backend>
<!-- A comma-separated list of path containing the medias to serve -->
<content>/media/path1,/media/path2</content>
<!-- The avertized media server name, default: "my media" -->
<name>my media</name>
<!-- The highest UPnP version this
media server should support, default: 2 -->
<version>2</version>
<!-- A unique identifier used to reference the media server,
autogenerated if not set explicitly. In this case, some control points
might memorize it between runs and display the same media server more
than once. -->
<uuid>2f7f4096-cba3-4390-be7d-d1d07106a6f4</uuid>

MediaStore
A MediaServer with a database backend,
exposes its content in All, Albums and Artists containers.
Serves cover art with the Album object, and keeps references to
the MusicBrainz DB - http://musicbrainz.org/
Should not scan for files, but gets feeded
with proper tagged ones via some import tool
or/and allow imports via the web-UI.
depends on:
for the sqlite db handling:
Axiom - http://divmod.org/trac/wiki/DivmodAxiom
Epsilon - http://divmod.org/trac/wiki/DivmodEpsilon
for id3 tag extraction:
libmtag - http://code.google.com/p/libmtag/
taglib - http://developer.kde.org/~wheeler/taglib.html
or
pyid3lib - http://pyid3lib.sourceforge.net/doc.html
or
tagpy - http://news.tiker.net/software/tagpy
taglib - http://developer.kde.org/~wheeler/taglib.html

"""A helper function to compute rewards.
The reward is computed by computing the value of a game state, and by comparing
it to the last state.
State values are computed by weighting different factor. Fainted pokemons,
their remaining HP, inflicted statuses and winning are taken into account.
For instance, if the last time this function was called for battle A it had
a state value of 8 and this call leads to a value of 9, the returned reward will
be 9 - 8 = 1.
Consider a single battle where each player has 6 pokemons. No opponent pokemon
has fainted, but our team has one fainted pokemon. Three opposing pokemons are
burned. We have one pokemon missing half of its HP, and our fainted pokemon has
no HP left.
The value of this state will be:
- With fainted value: 1, status value: 0.5, hp value: 1:
= - 1 (fainted) + 3 * 0.5 (status) - 1.5 (our hp) = -1
- With fainted value: 3, status value: 0, hp value: 1:
= - 3 + 3 * 0 - 1.5 = -4.5
:param battle: The battle for which to compute rewards.
:type battle: AbstractBattle
:param fainted_value: The reward weight for fainted pokemons. Defaults to 0.
:type fainted_value: float
:param hp_value: The reward weight for hp per pokemon. Defaults to 0.
