当前代码绘制的图片会出现下图中文字重叠的情况：
plt.subplot(211) plt.plot(epochs,loss,'bo',label='Training loss') plt.plot(epochs,val_loss,'b',label='Validation loss') plt.title('Training and Validation loss') plt.xlabel('Epochs') plt.ylabel('Loss') plt.legend() plt.subplot(212) plt.plot(epochs,acc,'ro',label='Training acc') plt.plot(epochs,val_acc,'r',label='Validation acc') plt.title('Training and Validation accuracy') plt.xlabel('Epochs') plt.ylabel('Acc') plt.legend() plt.show()
可通过tight_layout()方法解决，可根据自己喜好自动移参数：
plt.subplot(211) plt.plot(epochs,loss,'bo',label='Training loss') plt.plot(epochs,val_loss,'b',label='Validation loss') plt.title('Training and Validation loss') plt.xlabel('Epochs') plt.ylabel('Loss') plt.tight_layout() plt.legend() plt.subplot(212) plt.plot(epochs,acc,'ro',label='Training acc') plt.plot(epochs,val_acc,'r',label='Validation acc') plt.title('Training and Validation accuracy') plt.xlabel('Epochs') plt.ylabel('Acc') plt.tight_layout() plt.legend() plt.show()
