dimension 3000

Method One: Use the array map () method, which runs the given function for each item in an array, and returns a list of the results of each function call.var arr = [1,[2,[[3,4],5],6]]; function Unid (arr) { var arr1 = (arr + '). Split (', '); Convert the array to string and then comma-delimited to array var arr2 = Arr1.map (function(x) { return number (x); }); return arr2;} Console.log (Unid (ARRA));Law II: Using apply combined with concat, the disadvan

CentOS 7 operation and dimension optimization Generally, we install CentOS Mini and other corresponding services, we will be able to work properly. But after working for a while, the server will be unstable, invaded, and even immediately paralyzed at a sudden high concurrency. Most of these problems are due to the fact that we consider their actual compressive and safety reasons. So, here are some suggestions for operation-dimensional optimization. 1

Session () as Sess: a_, b_ = Sess.run ([A, b]) print ( ' A: ') print ( a_) print ( ' B: ') print (b_) Output results A: [1 2 3] B: [[1] [2] [3] ] Sample 2: [1, 2, 3] ==> [[1,2,3]] Import TensorFlow as tf a = Tf.constant ([1, 2, 3]) B = Tf.expand_di

After the Exchange project has been planned, deployed, and tested into the operations dimension, the administrator needs to master day-to-day maintenance, monitoring, and queue tracking basic management. In simple terms, the purpose of maintenance is to ensure the normal operation of the mail system and the timely recovery of data failure; The purpose of monitoring is to cut down the normal functioning of services and processes; The Exchange server qu

what is Cartesian product. In mathematics, the Cartesian product of two sets X and Y (Cartesian product), also called the direct product, is represented as XXY, the first object is the member of X and the second object is one of all possible ordered pairs of Y. Assuming collection a={a,b}, set b={0,1,2}, the Cartesian product of two sets is {(a,0), (a,1), (a,2), (b,0), (b,1), (b,2)}. how to achieve Cartesian product with program algorithm.
