枚举数组放置在torch.autograd.Variable中

Question

我有变量xy，它从文件加载数据，并用于创建x_data类型的y_data和torch.autograd.Variable变量。我想x_data和y_data的内容是数组。但是如何枚举该数组以打印内容？

d = r"C:\gdrive\python\diabetes.csv"
import torch
from torch.autograd import Variable 
import numpy as np
import torch.nn.functional as F
xy = np.loadtxt(d,delimiter=',',dtype=np.float32 )
print("***")
print(xy)
x_data = Variable(torch.from_numpy(xy[:,0:-1]))
y_data=  Variable(torch.from_numpy(xy[:,[-1]]))

Answer 1

您可以像对numpy数组和标准Python对象一样，枚举/迭代Pytorch张量。

Answer 2

您应该能够像python列表一样迭代pytorch张量：

import torch
from torch.autograd import Variable
import numpy as np
import torch.nn.functional as F

d = r"C:\gdrive\python\diabetes.csv"
xy = np.loadtxt(d, delimiter=',', dtype=np.float32)
print("***")
x_data = Variable(torch.from_numpy(xy[:,0:-1]))
y_data=  Variable(torch.from_numpy(xy[:,[-1]]))

print(x_data.shape)
print(y_data.shape)
for i, (x, y) in enumerate(zip(x_data, y_data)):
    print("example", i)
    print("featurers:", x)
    print("label:", y)
    print()
