WebOct 14, 2024 · model.fit (X_train,y_train,batch_size=batch_size,epochs=200) 这句出错了。 它说数据类型的问题,但是我整个过程都是tf.float32,我不知道咋就错了 完整错误如下: ValueError Traceback (most recent call last) in ----> 1 model.fit (X_train,y_train,batch_size=batch_size,epochs=200) WebIf I do model.fit(x, y, epochs=5) is this the same as for i in range(5) model.train_on_batch(x, y)? Yes. Your understanding is correct. There are a few more bells and whistles to .fit() (we, can for example, artificially control the number of batches to consider an epoch rather than exhausting the whole dataset) but, fundamentally, you are correct.
