class UNet(nn.Module):
"""Modified version of U-Net, adapted for 3D biomedical image segmentation
The U-Net is a convolutional encoder-decoder neural network.
Contextual spatial information (from the decoding, expansive pathway)
about an input tensor is merged with information representing the
localization of details (from the encoding, compressive pathway).
- Original paper: https://arxiv.org/abs/1505.04597
- Base implementation: https://github.com/jaxony/unet-pytorch
Modifications to the original paper (@jaxony):
- Padding is used in size-3-convolutions to prevent loss
of border pixels.
- Merging outputs does not require cropping due to (1).
- Residual connections can be used by specifying
UNet(merge_mode='add').
- If non-parametric upsampling is used in the decoder
pathway (specified by upmode='upsample'), then an
additional 1x1 convolution occurs after upsampling
to reduce channel dimensionality by a factor of 2.
This channel halving happens with the convolution in
the tranpose convolution (specified by upmode='transpose').
Additional modifications (@mdraw):
- Operates on 3D image data (5D tensors) instead of 2D data
- Uses 3D convolution, 3D pooling etc. by default
- Each network block pair (the two corresponding submodules in the
encoder and decoder pathways) can be configured to either work
in 3D or 2D mode (3D/2D convolution, pooling etc.)
with the `planar_blocks` parameter.
This is helpful for dealing with data anisotropy (commonly the
depth axis has lower resolution in SBEM data sets, so it is not
as important for convolution/pooling) and can reduce the complexity of
models (parameter counts, speed, memory usage etc.).
Note: If planar blocks are used, the input patch size should be
adapted by reducing depth and increasing height and width of inputs.
- Configurable activation function.
- Optional normalization
Gradient checkpointing can be used to reduce memory consumption while
training. To make use of gradient checkpointing, just run the
``forward_gradcp()`` instead of the regular ``forward`` method.
This makes the backward pass a bit slower, but the memory savings can be
huge (usually around 20% - 50%, depending on hyperparameters). Checkpoints
are made after each network *block*.
See https://pytorch.org/docs/master/checkpoint.html and
https://arxiv.org/abs/1604.06174 for more details.
Gradient checkpointing is not supported in TorchScript mode.
Args:
in_channels: Number of input channels
(e.g. 1 for single-grayscale inputs, 3 for RGB images)
Default: 1
out_channels: Number of output channels (in classification/semantic
segmentation, this is the number of different classes).
Default: 2
n_blocks: Number of downsampling/convolution blocks (max-pooling)
in the encoder pathway. The decoder (upsampling/upconvolution)
pathway will consist of `n_blocks - 1` blocks.
Increasing `n_blocks` has two major effects:
- The network will be deeper
(n + 1 -> 4 additional convolution layers)
- Since each block causes one additional downsampling, more
contextual information will be available for the network,
enhancing the effective visual receptive field.
(n + 1 -> receptive field is approximately doubled in each
dimension, except in planar blocks, in which it is only
doubled in the H and W image dimensions)
**Important note**: Always make sure that the spatial shape of
your input is divisible by the number of blocks, because
else, concatenating downsampled features will fail.
start_filts: Number of filters for the first convolution layer.
Note: The filter counts of the later layers depend on the
choice of `merge_mode`.
up_mode: Upsampling method in the decoder pathway.
Choices:
- 'transpose' (default): Use transposed convolution
("Upconvolution")
- 'resizeconv_nearest': Use resize-convolution with nearest-
neighbor interpolation, as proposed in
https://distill.pub/2016/deconv-checkerboard/
- 'resizeconv_linear: Same as above, but with (bi-/tri-)linear
interpolation
- 'resizeconv_nearest1': Like 'resizeconv_nearest', but using a
light-weight 1x1 convolution layer instead of a spatial convolution
- 'resizeconv_linear1': Like 'resizeconv_nearest', but using a
light-weight 1x1-convolution layer instead of a spatial convolution
merge_mode: How the features from the encoder pathway should
be combined with the decoder features.
Choices:
- 'concat' (default): Concatenate feature maps along the
`C` axis, doubling the number of filters each block.
- 'add': Directly add feature maps (like in ResNets).
The number of filters thus stays constant in each block.
Note: According to https://arxiv.org/abs/1701.03056, feature
concatenation ('concat') generally leads to better model
accuracy than 'add' in typical medical image segmentation
tasks.
planar_blocks: Each number i in this sequence leads to the i-th
block being a "planar" block. This means that all image
operations performed in the i-th block in the encoder pathway
and its corresponding decoder counterpart disregard the depth
(`D`) axis and only operate in 2D (`H`, `W`).
This is helpful for dealing with data anisotropy (commonly the
depth axis has lower resolution in SBEM data sets, so it is
not as important for convolution/pooling) and can reduce the
complexity of models (parameter counts, speed, memory usage
etc.).
Note: If planar blocks are used, the input patch size should
be adapted by reducing depth and increasing height and
width of inputs.
activation: Name of the non-linear activation function that should be
applied after each network layer.
Choices (see https://arxiv.org/abs/1505.00853 for details):
- 'relu' (default)
- 'silu': Sigmoid Linear Unit (SiLU, aka Swish)
- 'leaky': Leaky ReLU (slope 0.1)
- 'prelu': Parametrized ReLU. Best for training accuracy, but
tends to increase overfitting.
- 'rrelu': Can improve generalization at the cost of training
accuracy.
- Or you can pass an nn.Module instance directly, e.g.
``activation=torch.nn.ReLU()``
normalization: Type of normalization that should be applied at the end
of each block. Note that it is applied after the activated conv
layers, not before the activation. This scheme differs from the
original batch normalization paper and the BN scheme of 3D U-Net,
but it delivers better results this way
(see https://redd.it/67gonq).
Choices:
- 'group' for group normalization (G=8)
- 'group<G>' for group normalization with <G> groups
(e.g. 'group16') for G=16
- 'instance' for instance normalization
- 'batch' for batch normalization (default)
- 'none' or ``None`` for no normalization
attention: If ``True``, use grid attention in the decoding pathway,
as proposed in https://arxiv.org/abs/1804.03999.
Default: ``False``.
full_norm: If ``True`` (default), perform normalization after each
(transposed) convolution in the network (which is what almost
all published neural network architectures do).
If ``False``, only normalize after the last convolution
layer of each block, in order to save resources. This was also
the default behavior before this option was introduced.
dim: Spatial dimensionality of the network. Choices:
- 3 (default): 3D mode. Every block fully works in 3D unless
it is excluded by the ``planar_blocks`` setting.
The network expects and operates on 5D input tensors
(N, C, D, H, W).
- 2: Every block and every operation works in 2D, expecting
4D input tensors (N, C, H, W).
conv_mode: Padding mode of convolutions. Choices:
- 'same' (default): Use SAME-convolutions in every layer:
zero-padding inputs so that all convolutions preserve spatial
shapes and don't produce an offset at the boundaries.
- 'valid': Use VALID-convolutions in every layer: no padding is
used, so every convolution layer reduces spatial shape by 2 in
each dimension. Intermediate feature maps of the encoder pathway
are automatically cropped to compatible shapes so they can be
merged with decoder features.
Advantages:
- Less resource consumption than SAME because feature maps
have reduced sizes especially in deeper layers.
- No "fake" data (that is, the zeros from the SAME-padding)
is fed into the network. The output regions that are influenced
by zero-padding naturally have worse quality, so they should
be removed in post-processing if possible (see
``overlap_shape`` in :py:mod:`elektronn3.inference`).
Using VALID convolutions prevents the unnecessary computation
of these regions that need to be cut away anyways for
high-quality tiled inference.
- Avoids the issues described in https://arxiv.org/abs/1811.11718.
- Since the network will not receive zero-padded inputs, it is
not required to learn a robustness against artificial zeros
being in the border regions of inputs. This should reduce the
complexity of the learning task and allow the network to
specialize better on understanding the actual, unaltered
inputs (effectively requiring less parameters to fit).
Disadvantages:
- Using this mode poses some additional constraints on input
sizes and requires you to center-crop your targets,
so it's harder to use in practice than the 'same' mode.
- In some cases it might be preferable to get low-quality
outputs at image borders as opposed to getting no outputs at
the borders. Most notably this is the case if you do training
and inference not on small patches, but on complete images in
a single step.

An iterator that allows iteration over characters of strings or string iterators.
This class provides an interface for adding either strings or string iterators. When iterated upon,
it will yield characters from the added items. Additionally, it provides functionalities to stop
the iteration and accumulate iterated text.
Attributes:
items (List[Union[str, Iterator[str]]]): The list of strings or string iterators added to the CharIterator.
_index (int): The current index in the items list that is being iterated.
_char_index (int, optional): The current character index in the current string being iterated. None if currently iterating over an iterator.
_current_iterator (Iterator[str], optional): The current iterator being consumed. None if currently iterating over a string.
immediate_stop (threading.Event): An event signaling if the iteration should be stopped immediately.
iterated_text (str): Accumulates the characters that have been iterated over.
Methods:
add(item: Union[str, Iterator[str]]): Adds a string or a string iterator to the items list.
stop(): Stops the iterator immediately on the next iteration.

r"""
Function invoked when calling the pipeline for generation.
Args:
prompt (`str` or `List[str]`, *optional*):
The prompt or prompts to guide the image generation. If not defined, one has to pass `prompt_embeds`.
instead.
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.
guidance_scale (`float`, *optional*, defaults to 7.5):
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`).
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.
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.StableDiffusionPipelineOutput`] 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.cross_attention](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/cross_attention.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.
Examples:
Returns:

Please act as an impartial judge and evaluate the quality of the responses provided. You will rate the quality of the output on multiple aspects such as Helpfulness, Clarity, Factuality, Depth, and Engagement.
## Query:
${instruction}
## Output:
${candidate}
## Evaluate
### Aspects
- Helpfulness: Rate the response based on how well it addresses the user's query and provides a relevant solution. A score of 5 indicates the answer fully aids the user, while a 1 suggests it offers little to no help.
- Clarity: Rate the response based on how well-structured it is, with ideas presented in a clear and coherent manner. A high score of 5 means the answer is clear and logically structured, while a 1 suggests a disjointed or confusing reply.
- Factuality: Evaluate the factual accuracy and truthfulness of the information provided. A perfect 5 indicates the information is entirely correct and accurate, while a 1 suggests it has significant factual errors.
- Depth: Determine the level of detail and thoroughness in the response. A score of 5 means the answer delves deeply into the topic, while a 1 indicates it barely scratches the surface.
- Engagement: Assess how engaging and natural the response sounds in a conversational context. A high score of 5 reflects a response that feels engaging and human-like in its tone, while a 1 indicates a robotic or boring reply.
### Format
Given the query, please rate the quality of the output by scoring it from 1 to 5 individually on **each aspect**.
- 1: strongly disagree
- 2: disagree
- 3: neutral
- 4: agree
- 5: strongly agree
Now, please output your scores and a short rationale below in a json format by filling in the placeholders in []:

"You are an accessibility assistant integrated in the NVDA screen reader that "

"user when something is a fact that comes from your training data versus an educated guess, "
"and always consider that the user is primarily accessing content using the keyboard and "
"a screen reader. When describing images, keep in mind that you are describing content to "

"an image that they cannot see. Please describe any relevant details such as names, participant "
"lists, or other information that would be visible to sighted users in the context of a call "

"window, a partial window or an individual control in an application user interface. Generate "
"a detailed but succinct visual description. If the image is a control, tell the user the type "
"of control and its current state if applicable, the visible label if present, and how the control "
"looks like. If it is a window or a partial window, include the window title if present, and "
"describe the rest of the screen, listing all sections starting from the top, and explaining the "

# Only in batch form, not really meant for production use of a search engine
#
# - Needs a trained model (via train.py)
# - Measures efficiency & effectiveness on 1 collection + multiple query sets (start a new experiment for another collection)
# - Allows to start new experiment from each of the 3 steps via modes:
#
# mode config-requirement
#
# 1) encode+index+search -> trained_model folder path
# 2) index+search -> continue_folder folder path pointing to an experiment started with 1)
# 3) search -> continue_folder folder path pointing to an experiment started with 2)
#
# - We can do a lot of hyperparameter studies starting from each step, or just run through a full pass once

and be a `torch.nn.Module` class.
Parameters:
pretrained_model_name_or_path_or_dict (`str` or `os.PathLike` or `dict`):
Can be either:
- A string, the model id (for example `google/ddpm-celebahq-256`) of a pretrained model hosted on
the Hub.
- A path to a directory (for example `./my_model_directory`) containing the model weights saved
with [`ModelMixin.save_pretrained`].
- A [torch state
dict](https://pytorch.org/tutorials/beginner/saving_loading_models.html#what-is-a-state-dict).
cache_dir (`Union[str, os.PathLike]`, *optional*):
Path to a directory where a downloaded pretrained model configuration is cached if the standard cache
is not used.
force_download (`bool`, *optional*, defaults to `False`):
Whether or not to force the (re-)download of the model weights and configuration files, overriding the
cached versions if they exist.
resume_download (`bool`, *optional*, defaults to `False`):
Whether or not to resume downloading the model weights and configuration files. If set to `False`, any
incompletely downloaded files are deleted.
proxies (`Dict[str, str]`, *optional*):
A dictionary of proxy servers to use by protocol or endpoint, for example, `{'http': 'foo.bar:3128',
| 'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request. |
