Restoring from checkpoint failed

when I restored the checkpoints:

with tf.Session() as sess:
saver = tf.train.import_meta_graph('/content/drive/My Drive/cifar-10/model/model.ckpt-199.meta')
saver.restore(sess, "/content/drive/My Drive/cifar-10/model/model.ckpt-199")

InvalidArgumentError: Restoring from checkpoint failed. This is most likely due to a mismatch between the current graph and the graph from the checkpoint. Please ensure that you have not altered the graph expected based on the checkpoint. Original error:

Cannot assign a device for operation model/grad_norm: Could not satisfy explicit device specification '/device:GPU:0' because no supported kernel for GPU devices is available.
