kerasのエラー ValueError: Initializer for variable embedding_11/embeddings/ is from inside a control-flo

Question

解決方法を知っている方が居れば、教えてくれると本当に助かります。

ValueError: Initializer for variable embedding_11/embeddings/ is from inside a control-flow construct, such as a loop or conditional. When creating a variable inside a loop or conditional, use a lambda as the initializer.
