我正在尝试在 tensorflow 版本 2.4.1 上并行化一个带有嵌入层的模型。但这给我带来了以下错误：

InvalidArgumentError: Cannot assign a device for operation sequential/emb_layer/embedding_lookup/ReadVariableOp: Could not satisfy explicit device specification '' because the node {{colocation_node sequential/emb_layer/embedding_lookup/ReadVariableOp}} was colocated with a group of nodes that required incompatible device '/job:localhost/replica:0/task:0/device:GPU:0'. All available devices [/job:localhost/replica:0/task:0/device:CPU:0,/job:localhost/replica:0/task:0/device:XLA_CPU:0,/job:localhost/replica:0/task:0/device:XLA_GPU:0,/job:localhost/replica:0/task:0/device:GPU:0].

     [[{{node sequential/emb_layer/embedding_lookup/ReadVariableOp}}]] [Op:__inference_train_function_631]

将模型简化为基本模型以使其可重现：

import tensorflow as tf
central_storage_strategy = tf.distribute.MirroredStrategy()
with central_storage_strategy.scope():
  user_model = tf.keras.Sequential([
       tf.keras.layers.Embedding(10,2,name = "emb_layer")
     ])
user_model.compile(optimizer=tf.keras.optimizers.Adagrad(0.1),loss="mse")
user_model.fit([1],[[1,2]],epochs=3) 

任何帮助将不胜感激。谢谢！
