Keras load_model错误“str”对象不可调用

问：

我在 Google Colab 中编码

我已经通过Autokeras创建模型并导出并保存

model = clf.export_model()
model.save(f'{data_path}')
model.summary()

如果我在同一会话中加载模型 - 没关系

但是当我下次在新会话中不加载模型时，我出现错误

from tensorflow.keras.models import load_model
model_x = load_model(f'{data_path}')

      4 
----> 5 model_x = load_model('model_x.keras')

我在 pyCharm 中尝试了相同的方法并得到了相同的结果
