Reference: - [Xception: Deep Learning with Depthwise Separable Convolutions]( https://arxiv.org/abs/1610.02357) (CVPR 2017) For image classification use cases, see [this page for detailed examples]( https://keras.io/api/applications/#usage-examples-for-image-classification-models). For transfer learning use cases, make sure to read the [guide to transfer learning & fine-tuning]( https://keras.io/guides/transfer_learning/). The default input image size for this model is 299x299. Note: each Keras Application expects a specific kind of input preprocessing. For Xception, call `tf.keras.applications.xception.preprocess_input` on your inputs before passing them to the model. `xception.preprocess_input` will scale input pixels between -1 and 1. Args: include_top: whether to include the fully-connected layer at the top of the network. weights: one of `None` (random initialization), 'imagenet' (pre-training on ImageNet), or the path to the weights file to be loaded. input_tensor: optional Keras tensor (i.e. output of `layers.Input()`) to use as image input for the model. input_shape: optional shape tuple, only to be specified if `include_top` is False (otherwise the input shape has to be `(299, 299, 3)`. It should have exactly 3 inputs channels, and width and height should be no smaller than 71. E.g. `(150, 150, 3)` would be one valid value. pooling: Optional pooling mode for feature extraction when `include_top` is `False`. - `None` means that the output of the model will be the 4D tensor output of the last convolutional block. - `avg` means that global average pooling will be applied to the output of the last convolutional block, and thus the output of the model will be a 2D tensor. - `max` means that global max pooling will be applied. classes: optional number of classes to classify images into, only to be specified if `include_top` is True, and if no `weights` argument is specified. classifier_activation: A `str` or callable. The activation function to use on the "top" layer. Ignored unless `include_top=True`. Set `classifier_activation=None` to return the logits of the "top" layer. When loading pretrained weights, `classifier_activation` can only be `None` or `"softmax"`. Returns: A `keras.Model` instance. >Nr zThe `weights` argument should be either `None` (random initialization), `imagenet` (pre-training on ImageNet), or the path to the weights file to be loaded.r r zWIf using `weights` as `"imagenet"` with `include_top` as true, `classes` should be 1000i+G) default_sizemin_size data_formatrequire_flattenweightsN)shape)tensorrchannels_first )r)rF block1_conv1)stridesuse_biasnameblock1_conv1_bn)axisrrelublock1_conv1_act)r@ block1_conv2)rrblock1_conv2_bnblock1_conv2_act)rrsame)rpaddingr)rblock2_sepconv1)r(rrblock2_sepconv1_bnblock2_sepconv2_actblock2_sepconv2block2_sepconv2_bn block2_pool)rr(rblock3_sepconv1_actblock3_sepconv1block3_sepconv1_bnblock3_sepconv2_actblock3_sepconv2block3_sepconv2_bn block3_pooliblock4_sepconv1_actblock4_sepconv1block4_sepconv1_bnblock4_sepconv2_actblock4_sepconv2block4_sepconv2_bn block4_poolblock _sepconv1_act _sepconv1 _sepconv1_bn _sepconv2_act _sepconv2 _sepconv2_bn _sepconv3_act _sepconv3 _sepconv3_bniblock13_sepconv1_actblock13_sepconv1block13_sepconv1_bnblock13_sepconv2_actblock13_sepconv2block13_sepconv2_bn block13_pooliblock14_sepconv1block14_sepconv1_bnblock14_sepconv1_actiblock14_sepconv2block14_sepconv2_bnblock14_sepconv2_actavg_pool predictions) activationravgmaxxceptionz.xception_weights_tf_dim_ordering_tf_kernels.h5models 0a58e3b7378bc2990ea3b43d5981f1f6) cache_subdir file_hashz4xception_weights_tf_dim_ordering_tf_kernels_notop.h5 b0042744bf5b25fce3cb969f33bebb97)!tfiogfileexists ValueErrorrobtain_input_shaperimage_data_formatlayersInputis_keras_tensorConv2DBatchNormalization ActivationSeparableConv2D MaxPooling2DaddrangestrGlobalAveragePooling2Dvalidate_activationDenseGlobalMaxPooling2Drget_source_inputsrModelrget_fileTF_WEIGHTS_PATHTF_WEIGHTS_PATH_NO_TOP load_weights) include_topr input_tensor input_shapepoolingclassesclassifier_activation img_input channel_axisxresidualiprefixinputsmodel weights_pathrN/var/www/myenv/lib/python3.10/site-packages/keras/src/applications/xception.pyXception2s G                                 rz,keras.applications.xception.preprocess_inputcCstj||ddS)Nrb)rmode)rpreprocess_input)rrrrrrksrz.keras.applications.xception.decode_predictionsr@cCstj||dS)N)top)rdecode_predictions)predsrrrrrrsr)rreterror)Tr NNNr r )N)r@)__doc__tensorflow.compat.v2compatv2rb keras.srcrkeras.src.applicationsrkeras.src.enginerkeras.src.layersrkeras.src.utilsrr tensorflow.python.util.tf_exportrr{r|rirrrPREPROCESS_INPUT_DOCformatPREPROCESS_INPUT_RET_DOC_TFPREPROCESS_INPUT_ERROR_DOCrrrrsJ        8
