quanlaibahua: 你好，我想问一下我的代码加上断电续训就是这样了，找了好久问题，能解惑吗 Traceback (most recent call last): File "D:\Python tf练习\class4\FASHION_FC\p16_fashion_train_ex3.py", line 27, in history = model.fit(x_train, y_train, batch_size=32, epochs=5, validation_data=(x_test, y_test), validation_freq=1, File "D:\python tf\envs\TF2.1\lib\site-packages\keras\utils\traceback_utils.py", line 70, in error_handler raise e.with_traceback(filtered_tb) from None File "D:\python tf\envs\TF2.1\lib\site-packages\tensorflow\python\lib\io\file_io.py", line 513, in recursive_create_dir_v2 _pywrap_file_io.RecursivelyCreateDir(compat.path_to_bytes(path)) tensorflow.python.framework.errors_impl.FailedPreconditionError: . is not a directory

奶油大兔子（学代码版）: 请问KeyError: 'The optimizer cannot recognize variable embedding/embeddings:0. This usually means you are trying to call the optimizer to update different parts of the model separately. Please call `optimizer.build(variables)` with the full list of trainable variables before the training loop or use legacy optimizer `tf.keras.optimizers.legacy.{self.__class__.__name__}.' 这个错误怎么解决呀
