python学习——绘制loss、acc学习曲线
两种方式
1.直接画
# model.fit返回acc和loss的日志 hist=model.fit(train_data, train_label, batch_size=64, epochs=2, validation_split=0.2, shuffle=True) # verbose = 0 为不在标准输出流输出日志信息,verbose = 1 为输出进度条记录,verbose = 2 为每个epoch输出一行记录 # 创建一个绘图窗口 plt.figure() acc = hist.history['acc'] val_acc = hist.history['val_acc'] loss = hist.history['loss'] val_loss = hist.history['val_loss'] epochs = range(len(acc)) plt.plot(epochs, acc, 'bo', label='Training acc') # 'bo'为画蓝色圆点,不连线 plt.plot(epochs, val_acc, 'b', label='Validation acc') plt.title('Training and validation accuracy') plt.legend() # 绘制图例,默认在右上角 plt.figure() plt.plot(epochs, loss, 'bo', label='Training loss') plt.plot(epochs, val_loss, 'b', label='Validation loss') plt.title('Training and validation loss') plt.legend() plt.show()
