Hi,

When running “rasa run --enable-api” using Rasa 2.8.15 I get the warning:

UserWarning: Converting sparse IndexedSlices(IndexedSlices(indices=Tensor("gradients/cond_grad/Identity_1:0", shape=(None,), dtype=int64), values=Tensor("gradients/cond_grad/Identity:0", shape=(None,), dtype=float32), dense_shape=Tensor("gradients/cond_grad/Identity_2:0", shape=(1,), dtype=int32))) to a dense Tensor of unknown shape. This may consume a large amount of memory.
  "shape. This may consume a large amount of memory." % value)

What should I do?

Nothing. This is normal. If you actually run out of memory, you will get another message or failure depending on the environment you’re in.
