ValueError：无法创建数据集（名称已存在）

我之前运行过一个类似的模型（但略有不同）并且只保存了重量。我在修改模型后删除了所有 h5 文件，并引发了这个错误。我已经搜索了所有可能的答案，但找不到解决方案。 我现在有点沮丧。我能做些什么来解决这个问题？

我的模型是

model_Unet_input = UNet(Input_layer)
model_SegNet_input = SegNet(Input_layer)

model_Unet_output = UNet.layers[-3].output
model_Segnet_output = SegNet.layers[-3].output

avg = tf.keras.layers.Average()([model_Unet_output,model_Segnet_output])
data_output1 = layers.Conv2D(2, 1, strides=1,kernel_initializer="he_normal")(avg)
data_ouput2 = layers.BatchNormalization()(data_output1)
model_Unet_SegNet = Model([UNet.input, SegNet.input],data_ouput2)

model_Unet_SegNet.summary()

model_Unet_SegNet_dir="/nobackup/projects/bddur22/eunji/dissertation/model/saved_models/Unet_SegNet_avg"
model_Unet_SegNet.compile(adam_optimizer, total_loss, metrics=metrics)
model_Unet_SegNet_checkpoint = ModelCheckpoint(os.path.join(model_Unet_SegNet_dir,'ckpt', 'unet_seg_model-{epoch:03d}-{iou_score:03f}-{val_iou_score:03f}-{loss:03f}-{val_loss:03f}.h5'), monitor="val_loss", verbose=1, save_best_only=True, mode="min")

print('model compile completed, model training starts',end='\n')

model_Unet_SegNet_history=model_Unet_SegNet.fit([x_train_processed_res,x_train_processed_res], 
y_train, verbose=1,batch_size = batch_size,
epochs = epochs,validation_data([x_val_processed_res,x_val_processed_res], y_val),
callbacks =[model_Unet_SegNet_checkpoint])

错误看起来像
