tf-slice-assign 0.0.1

A package to perform slice assignment in TensorFlow

tf-slice-assign

A tool for assignment to a slice in TensorFlow.

In TensorFlow, as opposed to Pytorch, it is currently impossible to assign to the slice of a tensor in a range of different settings. To mitigate this issue, tf-slice-assign introduces a single function that allows to do exactly this using tensor_scatter_nd_update.

Use

from tf_slice_assign import slice_assign

new_tensor = slice_assign(old_tensor, assignment, *slice_args)

You can find a relatively simple example here.

In the following table, I am trying to give the reasons as to why no mitigation for the current problem exists.

Link	Status
SO	No answer for dynamically shaped input
GH	Question is about tf.Variable
SO	Answers for tf.Variable or using tensor_scatter_update in a non-adaptable way
GH	Suggestion to use tensor_scatter_nd_update
GH	An answer suggest creating a mask, but a mask can actually be as difficult to create as the indices for tensor_scatter_nd_update
