我經歷this script,並有一個代碼塊,需要2個選項考慮,DataParallel和DistributedDataParallel這裏: if not args.distributed:
if args.arch.startswith('alexnet') or args.arch.startswith('vgg'):
model.features = torch.nn
我在我的代碼中做了一些修改,以便它不使用DataParallel和DistributedDataParallel。代碼如下: import argparse
import os
import shutil
import time
import torch
import torch.nn as nn
import torch.nn.parallel
import torch.back
net.forward運行我使用Python IDE spyder3.2.1在anaconda2,與python2.7,ubuntu14.04 代碼如下只是簡單的: import torch
from torch.autograd import Variable
import torch.nn as nn
import torch.nn.functional as F
import num
試圖總結我的頭圍繞如何梯度代表,以及如何autograd作品: import torch
from torch.autograd import Variable
x = Variable(torch.Tensor([2]), requires_grad=True)
y = x * x
z = y * y
z.backward()
print(x.grad)
#Variable
對於pytorch模型,我發現this tutorial解釋如何分類圖像。我試圖將相同的程序應用於初始模型。但是該模型對每個圖像失敗,我在加載 代碼: # some people need these three lines to make it work
#from torchvision.models.inception import model_urls
#name = 'incepti
