如何将灰度图变为热力图

import cv2
import matplotlib.pyplot as plt
image=cv2.imread("C:/Users/lenovo/Desktop/result/result/190_gty_f.tif",2)//读取灰度图像
image1=cv2.applyColorMap(image, cv2.COLORMAP_JET)
# image1 = cv2.cvtColor(image,cv2.COLOR_GRAY2BGR)
cv2.imwrite("C:/Users/lenovo/Desktop/result/result/0.tif",image1)//保存热力图
plt.imshow(image1)
plt.show()
