This is not the right code for an indicated article. Can you share the updated code?
MultiScale_Intergrate should not remove the grad_fn?
Should we use F.interpolate instead of resizing it to prevent grad_fn disapeering?
Code Issue?
extractor = ModelOutputs(cls_net)
features, fc_output = extractor(cls_input)
cam_all_sr = {'size256': [], 'size128': [], 'size64': [], 'size32': []}
for batch in range(fc_output.shape[0]):
device = fc_output[batch].device.index
index = np.argmax(fc_output[batch].cpu().data.numpy())
if index == 0:
one_hot = np.zeros((1, fc_output[batch].size()[-1]), dtype=np.float32)
one_hot[0][0] = 1
if index > 0:
one_hot = np.ones((1, fc_output[batch].size()[-1]), dtype=np.float32)
one_hot[0][0] = 0
if batch == 0:
one_hot_all = Variable(torch.from_numpy(one_hot).cuda(device), requires_grad=True)
else:
one_hot_all = torch.cat((Variable(torch.from_numpy(one_hot).cuda(device), requires_grad=True), one_hot_all), 0)
if the index of batches is the same, there is no problem. But if they are different, it calculates the opposite loss between one_hot_all and fc_output.
Example:
fc_output one_hot_all
[[0.9, 0.1, 0.1, 0.1, 0.1] [[1, 0, 0, 0, 0]
[0.8, 0.2, 0.2, 0.3, 0.4]] [1, 0, 0, 0, 0]] There is no problem.
fc_output one_hot_all
[[0.2, 0.1, 0.1, 0.1, 0.8] [[0, 1, 1, 1, 1]
[0.3, 0.2, 0.7, 0.3, 0.4]] [0, 1, 1, 1, 1]] There is no problem.
fc_output one_hot_all
[[0.9, 0.1, 0.1, 0.1, 0.7] [[0, 1, 1, 1, 1]
[0.3, 0.2, 0.4, 0.9, 0.4]] [1, 0, 0, 0, 0]] There is problem here because of this line torch.cat((Variable(torch.from_numpy(one_hot).cuda(device), requires_grad=True), one_hot_all), 0).
should be one_hot_all = torch.cat((one_hot_all, Variable(torch.from_numpy(one_hot).cuda(device), requires_grad=True)), 0) ???
Thanks
GMSV algorithm?
Can you share the code of the GMSV algorithm in the article, not in the conference paper?
RandomCrop如何导入
您好,可以麻烦问一下这个怎么导入嘛?我搜不到这个库呀?
from transform.transforms_group import RandomCrop
我运行代码,一直在这个地方报错是怎么回事呢?
if self.transform is not None: # train
info = self.hr_transform(info)
报错如下
File "E:\MyUse\CVcode\DR-main\data_process.py", line 91, in getitem
info = self.hr_transform(info)

raise TypeError("Unexpected type {}".format(type(img)))

there is no U_Net_Cut model in network file?
Can you update the files?
about the number of epochs
您好,请问在第一阶段训练中,epoch数真的是30000吗?
