This image processor 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). Args: clusters (`np.ndarray` or `List[List[int]]`, *optional*): The color clusters to use, of shape `(n_clusters, 3)` when color quantizing. Can be overriden by `clusters` in `preprocess`. do_resize (`bool`, *optional*, defaults to `True`): Whether to resize the image's dimensions to `(size["height"], size["width"])`. Can be overridden by `do_resize` in `preprocess`. size (`Dict[str, int]` *optional*, defaults to `{"height": 256, "width": 256}`): Size of the image after resizing. Can be overridden by `size` in `preprocess`. resample (`PILImageResampling`, *optional*, defaults to `Resampling.BILINEAR`): Resampling filter to use if resizing the image. Can be overridden by `resample` in `preprocess`. do_normalize (`bool`, *optional*, defaults to `True`): Whether to normalize the image pixel value to between [-1, 1]. Can be overridden by `do_normalize` in `preprocess`. do_color_quantize (`bool`, *optional*, defaults to `True`): Whether to color quantize the image. Can be overridden by `do_color_quantize` in `preprocess`. pixel_valuesNTr3 do_resizesizeresample do_normalizedo_color_quantizereturnc t|di|||nddd}t|}|tj|nd|_||_||_||_||_ ||_ y)N)heightwidth) super__init__r r!arrayr3r8r9r:r;r<) selfr3r8r9r:r;r<kwargs __class__s r+rDzImageGPTImageProcessor.__init__Usl "6"'tc-JT".6.B* "   (!2r-image data_formatinput_data_formatc t|}d|vsd|vrtd|j|d|df}t|f||||d|S)a Resize an image to `(size["height"], size["width"])`.

If unset, the channel dimension format of the input image is used. Can be one of: - `"channels_first"` or `ChannelDimension.FIRST`: image in (num_channels, height, width) format. - `"channels_last"` or `ChannelDimension.LAST`: image in (height, width, num_channels) format. - `"none"` or `ChannelDimension.NONE`: image in (height, width) format. input_data_format (`ChannelDimension` or `str`, *optional*): The channel dimension format for the input image. If unset, the channel dimension format is inferred from the input image. Can be one of: - `"channels_first"` or `ChannelDimension.FIRST`: image in (num_channels, height, width) format. - `"channels_last"` or `ChannelDimension.LAST`: image in (height, width, num_channels) format. - `"none"` or `ChannelDimension.NONE`: image in (height, width) format. Returns: `np.ndarray`: The resized image. r@rAzFThe `size` dictionary must contain the keys `height` and `width`.

If passing in images with pixel values between 0 and 1, set `do_normalize=False`. do_resize (`bool`, *optional*, defaults to `self.do_resize`): Whether to resize the image. size (`Dict[str, int]`, *optional*, defaults to `self.size`): Size of the image after resizing. resample (`int`, *optional*, defaults to `self.resample`): Resampling filter to use if resizing the image. This can be one of the enum `PILImageResampling`, Only has an effect if `do_resize` is set to `True`. do_normalize (`bool`, *optional*, defaults to `self.do_normalize`): Whether to normalize the image do_color_quantize (`bool`, *optional*, defaults to `self.do_color_quantize`): Whether to color quantize the image. clusters (`np.ndarray` or `List[List[int]]`, *optional*, defaults to `self.clusters`): Clusters used to quantize the image of shape `(n_clusters, 3)`. Only has an effect if `do_color_quantize` is set to `True`. return_tensors (`str` or `TensorType`, *optional*): The type of tensors to return. Can be one of: - Unset: Return a list of `np.ndarray`. - `TensorType.TENSORFLOW` or `'tf'`: Return a batch of type `tf.Tensor`. - `TensorType.PYTORCH` or `'pt'`: Return a batch of type `torch.Tensor`. - `TensorType.NUMPY` or `'np'`: Return a batch of type `np.ndarray`. - `TensorType.JAX` or `'jax'`: Return a batch of type `jax.numpy.ndarray`. data_format (`ChannelDimension` or `str`, *optional*, defaults to `ChannelDimension.FIRST`): The channel dimension format for the output image. Can be one of: - `ChannelDimension.FIRST`: image in (num_channels, height, width) format. - `ChannelDimension.LAST`: image in (height, width, num_channels) format.

NzkInvalid image type. Must be of type PIL.Image.Image, numpy.ndarray, torch.Tensor, tf.Tensor or jax.ndarray.)r8r9r:z8Clusters must be specified if do_color_quantize is True.rzIt looks like you are trying to rescale already rescaled images. If you wish to do this, make sure to set `do_normalize` to `False` and that pixel values are between [-1, 1].)rIr9r:rK)rIrKr/)input_channel_dim input_ids)data tensor_type)r8r9r r:r;r<r3r!rErrrMrrrlogger warning_oncerr rRr rLASTr4r0shapelistr )rFrSr8r9r:r;r<r3rTrJrKrI batch_sizerXs r+ preprocessz!ImageGPTImageProcessor.preprocesss`l"+!6IDNN 'tTYYT"'38'3'?|TEVEV 1B1N-TXTjTj'3888H%$V,F#:  & !1WX X6<vay I  $ %dXYj kF djk[`dnn5DUnVkFk pvwgl1%9I9N9NPabwFwXXf%F#FH5==fll3B>OPF aJ^^J3F&\F$,E;RcdF V$>BBQ= lxsHH6H"H!*H&)NN)__name__ __module__ __qualname____doc__model_input_namesrBILINEARrrrintr!ndarrayboolrstrrDrr rRrFIRSTrrPILImager` __classcell__)rHs@r+r6r6;s.(( BF#'9'B'B!"&35d3i"**!<=>3 3 38n 3 % 33 3 34(:'B'B>BDH . zz. 38n. % . eC)9$9:; . $E#/?*?$@A .  . f?CDH zzeC)9$9:;$E#/?*?$@A   *%&#'+!,0AE;?>N>T>TDHzCzCzC38n zC % zC  zC$D>zC5d3i"**!<=>zC!sJ!78zCeC)9$9:;zC$E#/?*?$@AzC zC'zCr-r6)&rdtypingrrrrnumpyr!image_processing_utilsrr r image_transformsr r r image_utilsrrrrrrrrrutilsrrrrrl get_loggerrarZr,r4r6rBr-r+rvsq*..UULL   _^   H %  pC/pCr-
