Reference: - [Rethinking the Inception Architecture for Computer Vision]( http://arxiv.org/abs/1512.00567) (CVPR 2016) This function returns a 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 Keras Application expects a specific kind of input preprocessing. For `InceptionV3`, call `tf.keras.applications.inception_v3.preprocess_input` on your inputs before passing them to the model. `inception_v3.preprocess_input` will scale input pixels between -1 and 1. Args: include_top: Boolean, whether to include the fully-connected layer at the top, as the last layer of the network. Default to `True`. weights: One of `None` (random initialization), `imagenet` (pre-training on ImageNet), or the path to the weights file to be loaded. Default to `imagenet`. input_tensor: Optional Keras tensor (i.e. output of `layers.Input()`) to use as image input for the model. `input_tensor` is useful for sharing inputs between multiple different networks. Default to None. input_shape: Optional shape tuple, only to be specified if `include_top` is False (otherwise the input shape has to be `(299, 299, 3)` (with `channels_last` data format) or `(3, 299, 299)` (with `channels_first` data format). It should have exactly 3 inputs channels, and width and height should be no smaller than 75. E.g. `(150, 150, 3)` would be one valid value. `input_shape` will be ignored if the `input_tensor` is provided. pooling: Optional pooling mode for feature extraction when `include_top` is `False`. - `None` (default) 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. Default to 1000. 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. >r NzThe `weights` argument should be either `None` (random initialization), `imagenet` (pre-training on ImageNet), or the path to the weights file to be loaded; Received: weights=r r zjIf using `weights` as `"imagenet"` with `include_top` as true, `classes` should be 1000; Received classes=i+K)Z default_sizeZmin_size data_formatZrequire_flattenweightsN)shape)Ztensorrchannels_first )rZvalid)stridespadding)r@)rr)rP0`rrsameZmixed0)axisnameZmixed1Zmixed2iZmixed3Zmixed4rZmixedZmixed7i@Zmixed8Zmixed9_i)r Zavg_poolr Z predictions)Z activationr ZavgmaxZ inception_v3z2inception_v3_weights_tf_dim_ordering_tf_kernels.h5ZmodelsZ 9a0d58056eeedaa3f26cb7ebd46da564)Z cache_subdirZ file_hashz8inception_v3_weights_tf_dim_ordering_tf_kernels_notop.h5Z bcbd6486424b2319ff4ef7d526e38f63)tfioZgfileexists ValueErrorrZobtain_input_shaperimage_data_formatlayersZInputZis_keras_tensor conv2d_bnZ MaxPooling2DZAveragePooling2DZ concatenaterangestrZGlobalAveragePooling2DZvalidate_activationZDenseZGlobalMaxPooling2DrZget_source_inputsrZModelrZget_file WEIGHTS_PATHWEIGHTS_PATH_NO_TOPZ load_weights)Z include_toprZ input_tensorZ input_shapeZpoolingZclassesZclassifier_activationZ img_inputZ channel_axisxZ branch1x1Z branch5x5Z branch3x3dblZ branch_poolZ branch3x3Z branch7x7Z branch7x7dbliZ branch7x7x3Z branch3x3_1Z branch3x3_2Zbranch3x3dbl_1Zbranch3x3dbl_2ZinputsZmodelZ weights_pathr4?lib/python3.10/site-packages/keras/applications/inception_v3.py InceptionV3/sJ                            r6rrc Cs|dur |d}|d}nd}d}tdkrd} nd} tj|||f||d|d|}tj| d|d |}tjd |d |}|S) aUtility function to apply conv + BN.
