Question

我是一名使用python 3的初学者

我需要在一系列txt文件中减去两个不同的矩阵，并在一个txt文件中得到所有结果。代码工作，直到我要求打印（并且它确实），但当我想保存“ncol = X.shape [1] indecerror：元组索引超出范围”时，我不断收到错误消息“

这是代码

import sys, os

import numpy as np
from PIL import Image

newpath = "C:/Users/.../PycharmProjects/.../output/differenza"

os.makedirs(newpath)

for txt in range(162, 167):

    #fn = "C:/Users/.../PycharmProjects/.../output" + str(txt).zfill(0) + ".txt"

    v1 = np.loadtxt("C:/Users/.../PycharmProjects/.../output/result_628.txt")

    v2 = np.loadtxt("C:/Users/.../PycharmProjects/.../output/result_" + str(txt).zfill(1) + ".txt")

    v3 = v1 - v2

    picture = np.sum(v3)

    print("picture", picture)

    outfn = newpath + "/result_" + str(txt) + ".txt"

    np.savetxt("outfn", picture, fmt='%1.3f')

Answer 1

一起去：

import sys, os
import numpy as np
from PIL import Image

newpath = "C:/Users/.../PycharmProjects/.../output/differenza"

os.makedirs(newpath)

final = np.array()

for txt in range(162, 167):

    #fn = "C:/Users/.../PycharmProjects/.../output" + str(txt).zfill(0) + ".txt"

    v1 = np.loadtxt("C:/Users/.../PycharmProjects/.../output/result_628.txt")

    v2 = np.loadtxt("C:/Users/.../PycharmProjects/.../output/result_" + str(txt).zfill(1) + ".txt")

    v3 = v1 - v2

    picture = np.sum(v3)

    print("picture", picture)
    np.append(final, picture)


np.savetxt("outfn.txt", final, fmt='%1.3f')

Answer 2

你的v3可能只是一个标量值（由numpy.sum（）返回），而numpy.savetxt（）需要一个array_like对象。

您可以np.savetxt("outfn", [picture,], fmt='%1.3f')或zipa建议。但是你确定要用一个标量值来编写多个文件吗？

PS：我会把它放到评论中，但我还不允许:(

使用矩阵并将所有内容保存在一个txt文件中
