tensorflow - How to understand constructor of tf.FIFOQueue? -


i have written code, can't explain well.

the first code:

import tensorflow tf  f = tf.fifoqueue(10, [tf.int32, tf.int32]) en = f.enqueue([[1,2],[3,4]]) de = f.dequeue() tf.session() sess:     en.run()     x = sess.run(de)     print(x)

i define element of queue tuple of tensor, when enqueue [[1,2],[3,4]], works , output [array([1, 2]), array([3, 4])].

but second code, can't understand.

import tensorflow tf  f = tf.fifoqueue(10, [tf.int32]) en = f.enqueue([1,2,3,4]) de = f.dequeue() tf.session() sess:     en.run()     x = sess.run(de)     print(x)

according first code, think output [array(1, 2, 3, 4)], in fact, output 1. how explain second code?

if change arguments in enqueue operation of second code to:

en = f.enqueue([[1,2,3,4]])

you have results supposed.

you can use shape argument in constructor of tf.fifoqueue more definiteness. example if change code as:

import tensorflow tf  f = tf.fifoqueue(10, [tf.int32], shapes = [4]) en = f.enqueue([1,2,3,4]) de = f.dequeue() tf.session() sess:     en.run()     x = sess.run(de)     print(x)

you receive error on f.enqueue operation.

but if use this:

import tensorflow tf  f = tf.fifoqueue(10, [tf.int32], shapes = [4]) en = f.enqueue([[1,2,3,4]]) de = f.dequeue() tf.session() sess:     en.run()     x = sess.run(de)     print(x)

you have no errors.

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);
