Reference: - [Densely Connected Convolutional Networks]( https://arxiv.org/abs/1608.06993) (CVPR 2017) This function returns a TF-Keras image classification model, optionally loaded with weights pre-trained on ImageNet. 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/). Note: each TF-Keras Application expects a specific kind of input preprocessing. For DenseNet, call `tf.keras.applications.densenet.preprocess_input` on your inputs before passing them to the model. `densenet.preprocess_input` will scale pixels between 0 and 1 and then will normalize each channel with respect to the ImageNet dataset statistics. Args: blocks: numbers of building blocks for the four dense layers. 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 TF-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 `(224, 224, 3)` (with `'channels_last'` data format) or `(3, 224, 224)` (with `'channels_first'` data format). It should have exactly 3 inputs channels, and width and height should be no smaller than 32. E.g. `(200, 200, 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. >NimagenetzThe `weights` argument should be either `None` (random initialization), `imagenet` (pre-training on ImageNet), or the path to the weights file to be loaded.rJzWIf using `weights` as `"imagenet"` with `include_top` as true, `classes` should be 1000r) default_sizemin_size data_formatrequire_flattenweights)shape)tensorrRr r!r)r!r!rT)rD@r,Fz conv1/conv)r/r+rr"zconv1/bnr$r'z conv1/relur)rrrWpool1r.rconv2g?pool2conv3pool3conv4pool4conv5bnavg_pool predictions) activationravgmaxmax_pool  densenet121rhrirr densenet169rhri0r densenet201densenetr models 9d60b8095a5708f2dcce2bca79d332c7) cache_subdir file_hashr d699b8f76981ab1b30698df4c175e90br 1ceb130c1ea1b78c3bf6114dbdfd8807r 30ee3e1110167f948a6b9946edeeb738r b8c4d4c20dd625c148057b9ff1c1176br c13680b51ded0fb44dff2d8f86ac8bb1)$tfiogfileexists ValueErrorrobtain_input_shaperr0r1Inputis_keras_tensor ZeroPadding2Dr4r2r3 MaxPooling2Drr:GlobalAveragePooling2Dvalidate_activationDenseGlobalMaxPooling2Drget_source_inputsrModelrget_fileDENSENET121_WEIGHT_PATHDENSENET169_WEIGHT_PATHDENSENET201_WEIGHT_PATHDENSENET121_WEIGHT_PATH_NO_TOPDENSENET169_WEIGHT_PATH_NO_TOPDENSENET201_WEIGHT_PATH_NO_TOP load_weights)r include_toprQ input_tensor input_shapepoolingclassesclassifier_activation img_inputr9rinputsmodel weights_paths rDenseNetrs^T ) )RUU[[-?-?-H <  *D 1  !33--/# KLL{L3 &&|4 L LI$I,,./AaqG%56yAA b!Q\ J1MA!! hZ "  A &|4Q7A%56q9AAqw7:AAvayw/ACg.AAvayw/ACg.AAvayw/ACg.AAvayw/A!!wt!LQOA&v.q1A  ) )z ) :1 =**+@'J LL  5M    e --:->qAA  ))z):1=A..|< vq}= ?
