Sets summary recording on or off per the provided boolean value.

The provided value can be a python boolean, a scalar boolean Tensor, or or a callable providing such a value; if a callable is passed it will be invoked on-demand to determine whether summary writing will occur. Note that when calling record_if() in an eager mode context, if you intend to provide a varying condition like step % 100 == 0, you must wrap this in a callable to avoid immediate eager evaluation of the condition. In particular, using a callable is the only way to have your condition evaluated as part of the traced body of an @tf.function that is invoked from within the record_if() context.
