The input arrays for the boolean mask function have the same size as the expected output of the boolean mask. Create a mask tensor. tf.ragged.boolean_mask. axis: A 0-D int Tensor representing the axis in tensor to mask from. It is called fancy indexing, if arrays are indexed by using boolean or integer arrays (masks). – rafaelvalle … axis : A 0-D int Tensor representing the axis in tensor to mask … If you pass a bool tensor, it is interpretet as a mask and will return the entries where True is given. So an alternative is to use where and gather as @Jackson Loper suggested. With Theano you can use bool_mask.nonzero() to get the indices of the boolean mask. See Migration guide for more details. You can use tf.boolean_mask(original_tensor, mask) to keep only the values that you want (you'll remove the other ones instead of setting them to 0).. To keep the initial shape and just have zeros in some places, you can just do something like that: new_tensor = tf.multiply(original_tensor, tf.cast(mask, original_tensor.type())) Overview of the Mask_RCNN Project. Setup import numpy as np import tensorflow as tf from tensorflow import keras from tensorflow.keras import layers Introduction. We will write some examples to illustrate how to use it.

An Open Source Machine Learning Framework for Everyone - tensorflow/tensorflow If I change the first dimension in the example below to 20000, processing is not an issue. x = [0, 1, 3, 5] And I want to get a tensor with dimensions. I can't figure out how to do the equivalent of this in TensorFlow. tf.compat.v1.ragged.boolean_mask, `tf.compat.v2.ragged.boolean … Wrapping this in a torch.ByteTensor() will recover the mask behavior. In our next example, we will use the Boolean mask of one array to select the corresponding elements of another array. TensorFlow version: v2.0.0-rc2-26-g64c3d382ca 2.0.0; Python version: 3.7.4; CUDA/cuDNN version: None; GPU model and memory: NO GPU; Describe the current behavior A function containing tf.ragged.boolean_mask and decorated with tf.function works on first execution but fails when executed axis: A 0-D int Tensor representing the axis in tensor to mask from. Suppose I have a list. If the layer’s call method takes a mask argument (as some Keras layers do), its default value will be set to the mask generated for inputs by the previous layer (if input did come from a layer that generated a corresponding mask, i.e. We will explore how we can export Mask R-CNN to tflite so that it can be used on mobile devices such as Android smartphones. When working with too big arrays, boolean crashes probably because of using int32 internally for indexing. tf.tile([1,0], num_of_repeats) might be a fast way to create such mask but not that great either if you have odd number of columns. A more powerful pattern is to use Boolean arrays as masks, to select particular subsets of the data themselves. Because TensorFlow 2.0 offers more features and enhancements, developers are looking to migrate to TensorFlow 2.0. Did you cast your mask to type boolean? Glasses detected with Mask R-CNN.
