deep learning - in Torch, why is NIN and VGG19 network 1-top predicting always 670? -


i'm working torch7 on ubuntu, i'm trying apply deep neural network trained on imagenet2012 such nin or vgg19 single image.

this code.

require('image') require('nn') require('pretty-nn')   net = torch.load('nin_test/nin_imagenet_w_model.t7') --net = torch.load('nin_test/vgg_19_w_model.t7') net:evaluate()  images = image.load('nin_test/5ee446f7fdedd01db6c7ea3d43df72b46807911b.thumb.jpeg')   mean= torch.tensor({0.485, 0.456, 0.406}) std =torch.tensor({0.229, 0.224, 0.225})  images3 = image.scale(images, 224, 224,'bilinear')  i=1,3      images3[i] = images3[i]:add(-mean[i]):div(std[i])  end  image.display{image = images3}  output = net:forward(images3):view(-1)  classes indices = torch.sort(output, true)

when test different images example image of human, cat, dog, bird , etc 1-top predict 670th class or label, means

t7> return  indices[1] 670

what should do? what's problem?

vue.js - Create hooks for automated testing -

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...

Add new key value to json node in java -

i have json file : { "id":1, "name":"abc", "addressdetails": { "city":"newyork" } } i wanted add 1 more key-value ("pincode" : "414141") node 'addressdetails'. i tried using : objectmapper mapper = new objectmapper(); jsonnode root = mapper.readtree(new file("d://test.json")); objectnode node = mapper.createobjectnode(); node.with("addressdetails").put("pincode", "414141"); but it's not getting added, there way can ? you can try you should modify file path objectmapper mapper = new objectmapper(); objectnode nodes = mapper.readvalue(new file("d:\\test.txt"), objectnode.class); nodes.with("addressdetails").put("pincode", "414141"); mapper.writer().writevalue(new file("d:\\test.txt"), nodes);
