修正成這樣就好了

import matplotlib.pyplot as plt

def show_train_history(history):

    fig, ax = plt.subplots(figsize=(16, 6))

    # Accessing the history data from the History object

    plt.plot(history.history["accuracy"], label='Training Accuracy')

    plt.plot(history.history["val_accuracy"], label='Validation Accuracy')

    plt.xlabel('Epoch')

    plt.ylabel('Accuracy')

    plt.legend()

    plt.title("Train History")

    plt.show()

# Assuming you have a model `model` and training data `x_train`, `y_train`, etc.

history = model.fit(x_train, y_train, batch_size=64, epochs=10, validation_data=(x_test, y_test), verbose=1)

# Call the function to display the plots

show_train_history(history)
