Feedable

Feedables can be fed into a TensorFlow session to fix the values of certain tensors to the provided values.

For example, values for placeholder ops can be fed into TensorFlow sessions.

Currently supported feedable types are:

• Output whose fed value should be a single Tensor.
• OutputIndexedSlices whose fed value should be tuple Tensor, Tensor).
• SparseOutput whose fed value should be tuple Tensor, Tensor).

Feedables are fed into TensorFlow sessions through the use of FeedMaps. Any Map that uses a feedable type as the keys type and its corresponding value type as its values type is a valid feed map.
