Is there an idiom or API for synchronized shuffling of Python arrays? -


is there api in numpy (or perhaps tensorflow) performing synchronized shuffling of several arrays (with same first dimension)?

for example, if 2 arrays dimensions (n, a) , (n, b), , want randomize ordering of n elements of each, while maintaining association between elements of first array , second.

is there api or python idiom accomplishing this?

note combining these single array of n tuples shuffled random.shuffle might option i'd accept answer, can't work: getting original arrays (as near i've managed) messy since combined_array[:,0] have dimension (n,) objects elements, rather dimension (n, a), unless manually rebuilt like [x x in combined_array[:,0]

permutation = numpy.random.permutation(n)  arr1_shuffled = arr1[permutation] arr2_shuffled = arr2[permutation]

pick 1 permutation , use both arrays.

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 ...
