AssertionError: Tried to export a function which references untracked resource Tensor("lambda_1/l2_normalize:0", shape=(209, 16), dtype=float32). TensorFlow objects (e.g. tf.Variable) captured by functions must be tracked by assigning them to an attribute of a tracked object or assigned to an attribute of the main object directly.

Trackable Python objects referring to this tensor (from gc.get_referrers, limited to two hops):

Operating environment(运行环境):

• python version [3.8]
