autoencoder - Feeding a hidden tensor in Tensorflow -


i have autoencoder. model not important now. suppose model takes input image , output reconstructed image. after training, see effect of 1 tensor on output. in addition, images being fed autoencoder through fifoqueue. therefore, when running following peace of code:

reconstructed_image = sess.run([deconv_image], feed_dict={mu:my_vector})

where deconv_image output tensor of model , mu hidden tensor inside model; automatically feed model image queue.

my question is: value inside mu replaced whatever should come input image, or, takes vector fed using feed_dict argument.

any appreciated!!

when running final tensor, is, evaluating last tensor of graph, run tensors depends on. if have y3 operation depends on y2 , y2 depends on y1, then, running final tensor in graph cause y1 run first, y2 evaluated after gets input y1 , finally, output of y2 feed y3. graph follows: y1 -> y2 -> y3

on other hand, can run (evaluate) y3 feeding inputs directly using feed_dict argument. in case, y2 , y1 evaluated.

ex:

import tensorflow tf import numpy np  x = np.array([1.0, 2.0, 3.0])  x_var = tf.variable(x, dtype=tf.float32)  y1 = tf.square(x_var) y2 = tf.subtract(y1, tf.constant(1.0))  init_op = tf.global_variables_initializer()  tf.session() sess:     sess.run(init_op)      print(sess.run(y2)) # output: [ 0.  3.  8.]     print(sess.run(y2, feed_dict={y1: [1.0, 1.0, 1.0]}))# output: [ 0.  0.  0.]

vue.js - Create hooks for automated testing -

Image
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);
