# To construct a layer, simply construct the object. Most layers take as # a first argument the number of output dimensions / channels. layer <-layer_dense (units = 100) # The number of input dimensions is often unnecessary, as it can be inferred # the first time the layer is used, but it can be provided if you want to # specify it manually, which is useful in some complex models. layer Keyword Arguments. dtype (tensorflow.DType) – TensorFlow dtype. shape (tuple(int)) – Iterable container (usually a tuple) describing the shape of a tensor. inputs (list(tensorflow.NodeDef) or str) – Iterable container (usually a tuple) of input nodes or input node names.

There's no problem with slicing or tf.map_fn(). There seems to be a problem with y_pred. Reason: On iterating, tf.map_fn() returned elements of (None, 1) and slicing too returns this extra 1 at the end which is (None, None, 1). And this happens only with y_pred and not with y_true. Question: So, what's actually wrong with y_pred? 2021-04-07 · map_fn; meshgrid; name_scope; no_gradient; no_op; nondifferentiable_batch_function; norm; numpy_function; one_hot; ones; ones_initializer; ones_like; pad; parallel_stack; print; py_function; quantize_and_dequantize_v4; random_normal_initializer; random_uniform_initializer; range; rank; realdiv; recompute_grad; register_tensor_conversion_function; repeat; required_space_to_batch_paddings; reshape TensorFlow version: 1.10.1; Describe the documentation issue I am familiar with parsing tfrecord back to tensor without using tf.data API. And now I'm trying to use this API to construct a more robust pipeline. The code goes like this: `def parse_fn(serialized): features = {'image': tf.FixedLenFeature([], tf.string), Note: map_fn should only be used if you need to map a function over the rows of a RaggedTensor.

create variables, and for some reason tensorflow fails to initialize those variables 19 May 2017 Recently I started with Tensorflow for developing some RNN-based system.

Transforms elems by applying fn to each element unstacked on axis 0. (deprecated arguments) map_fn also supports functions with multi-arity inputs and outputs: If elems is a tuple (or nested structure) of tensors, then those tensors must all have the same outer-dimension size (num_elems); and fn is used to transform each tuple (or structure) of corresponding slices from elems.
