	<span>Overview
	</span></h2>

<p>The ImageGPT model was proposed in <a href="https://openai.com/blog/image-gpt" rel="nofollow">Generative Pretraining from Pixels</a> by Mark
Chen, Alec Radford, Rewon Child, Jeffrey Wu, Heewoo Jun, David Luan, Ilya Sutskever. ImageGPT (iGPT) is a GPT-2-like
model trained to predict the next pixel value, allowing for both unconditional and conditional image generation.</p>
<p>The abstract from the paper is the following:</p>
<p><em>Inspired by progress in unsupervised representation learning for natural language, we examine whether similar models
can learn useful representations for images. We train a sequence Transformer to auto-regressively predict pixels,
without incorporating knowledge of the 2D input structure. Despite training on low-resolution ImageNet without labels,
we find that a GPT-2 scale model learns strong image representations as measured by linear probing, fine-tuning, and
low-data classification. On CIFAR-10, we achieve 96.3% accuracy with a linear probe, outperforming a supervised Wide
ResNet, and 99.0% accuracy with full fine-tuning, matching the top supervised pre-trained models. We are also
competitive with self-supervised benchmarks on ImageNet when substituting pixels for a VQVAE encoding, achieving 69.0%
top-1 accuracy on a linear probe of our features.</em></p>

<small>Summary of the approach. Taken from the [original paper](https://cdn.openai.com/papers/Generative_Pretraining_from_Pixels_V2.pdf). </small>
<p>This model was contributed by <a href="https://huggingface.co/nielsr" rel="nofollow">nielsr</a>, based on <a href="https://github.com/openai/image-gpt/issues/7" rel="nofollow">this issue</a>. The original code can be found
<a href="https://github.com/openai/image-gpt" rel="nofollow">here</a>.</p>
<p>Tips:</p>
<ul><li>Demo notebooks for ImageGPT can be found
<a href="https://github.com/NielsRogge/Transformers-Tutorials/tree/master/ImageGPT" rel="nofollow">here</a>.</li>
<li>ImageGPT is almost exactly the same as <a href="gpt2">GPT-2</a>, with the exception that a different activation
function is used (namely “quick gelu”), and the layer normalization layers don’t mean center the inputs. ImageGPT
also doesn’t have tied input- and output embeddings.</li>
<li>As the time- and memory requirements of the attention mechanism of Transformers scales quadratically in the sequence
length, the authors pre-trained ImageGPT on smaller input resolutions, such as 32x32 and 64x64. However, feeding a
sequence of 32x32x3=3072 tokens from 0..255 into a Transformer is still prohibitively large. Therefore, the authors
applied k-means clustering to the (R,G,B) pixel values with k=512. This way, we only have a 32*32 = 1024-long
sequence, but now of integers in the range 0..511. So we are shrinking the sequence length at the cost of a bigger
embedding matrix. In other words, the vocabulary size of ImageGPT is 512, + 1 for a special “start of sentence” (SOS)
token, used at the beginning of every sequence. One can use <a href="/docs/transformers/pr_17548/en/model_doc/imagegpt#transformers.ImageGPTFeatureExtractor">ImageGPTFeatureExtractor</a> to prepare
images for the model.</li>
<li>Despite being pre-trained entirely unsupervised (i.e. without the use of any labels), ImageGPT produces fairly
performant image features useful for downstream tasks, such as image classification. The authors showed that the
features in the middle of the network are the most performant, and can be used as-is to train a linear model (such as
a sklearn logistic regression model for example). This is also referred to as “linear probing”. Features can be
easily obtained by first forwarding the image through the model, then specifying <code>output_hidden_states=True</code>, and
then average-pool the hidden states at whatever layer you like.</li>
<li>Alternatively, one can further fine-tune the entire model on a downstream dataset, similar to BERT. For this, you can
use <a href="/docs/transformers/pr_17548/en/model_doc/imagegpt#transformers.ImageGPTForImageClassification">ImageGPTForImageClassification</a>.</li>
<li>ImageGPT comes in different sizes: there’s ImageGPT-small, ImageGPT-medium and ImageGPT-large. The authors did also
train an XL variant, which they didn’t release. The differences in size are summarized in the following table:</li></ul>

<p>This is the configuration class to store the configuration of a <a href="/docs/transformers/pr_17548/en/model_doc/imagegpt#transformers.ImageGPTModel">ImageGPTModel</a> or a <code>TFImageGPTModel</code>. It is
used to instantiate a GPT-2 model according to the specified arguments, defining the model architecture.
Instantiating a configuration with the defaults will yield a similar configuration to that of the ImageGPT
<a href="https://huggingface.co/openai/imagegpt-small" rel="nofollow">openai/imagegpt-small</a> architecture.</p>
<p>Configuration objects inherit from <a href="/docs/transformers/pr_17548/en/main_classes/configuration#transformers.PretrainedConfig">PretrainedConfig</a> and can be used to control the model outputs. Read the
documentation from <a href="/docs/transformers/pr_17548/en/main_classes/configuration#transformers.PretrainedConfig">PretrainedConfig</a> for more information.</p>

<p>Constructs an ImageGPT feature extractor. This feature extractor can be used to resize images to a smaller
resolution (such as 32x32 or 64x64), normalize them and finally color quantize them to obtain sequences of “pixel
values” (color clusters).</p>
<p>This feature extractor inherits from <a href="/docs/transformers/pr_17548/en/main_classes/feature_extractor#transformers.FeatureExtractionMixin">FeatureExtractionMixin</a> which contains most of the main methods. Users
should refer to this superclass for more information regarding those methods.</p>

<p>The bare ImageGPT Model transformer outputting raw hidden-states without any specific head on top.</p>
<p>This model inherits from <a href="/docs/transformers/pr_17548/en/main_classes/model#transformers.PreTrainedModel">PreTrainedModel</a>. Check the superclass documentation for the generic methods the
library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
etc.)</p>
<p>This model is also a PyTorch <a href="https://pytorch.org/docs/stable/nn.html#torch.nn.Module" rel="nofollow">torch.nn.Module</a> subclass.
Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
and behavior.</p>

<p>The ImageGPT Model transformer with a language modeling head on top (linear layer with weights tied to the input
embeddings).</p>
<p>This model inherits from <a href="/docs/transformers/pr_17548/en/main_classes/model#transformers.PreTrainedModel">PreTrainedModel</a>. Check the superclass documentation for the generic methods the
library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
etc.)</p>
<p>This model is also a PyTorch <a href="https://pytorch.org/docs/stable/nn.html#torch.nn.Module" rel="nofollow">torch.nn.Module</a> subclass.
Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
and behavior.</p>
