pytorch如何把二维变成一维？
from PIL import Image#python3中image要从PIL中导入 import numpy as np def getTestImgArray(filename,imgHeight,imgWidth): im = Image.open(filename) x_s = imgWidth y_s = imgHeight im_arr = im.resize((x_s, y_s), Image.ANTIALIAS) nm = im_arr.reshape((1, imgHeight*imgHeight)
) nm = nm.astype(np.float32) return nm
