python - Sort images based on age -


i'm using following code load imdb dataset , mat file isolate them based on ages. following code loads mat file , computes age subtracting data in photo taken date of birth

from scipy.io import loadmat datetime import datetime import os import  numpy np shutil import copy db = "imdb" mat_path = "data/{}_crop/{}.mat".format(db, db) print (mat_path) dataset = loadmat(mat_path) face_score_treshold = 3 path_root = "data/{}_crop/".format(db) def calc_age(taken, dob):     birth = datetime.fromordinal(max(int(dob) - 366, 1))      # assume photo taken in middle of year     if birth.month < 7:         return taken - birth.year     else:         return taken - birth.year - 1   image_names_array = dataset['imdb']['full_path'][0, 0][0] dob = dataset[db][0, 0]["dob"][0]  # matlab serial date number photo_taken = dataset[db][0, 0]["photo_taken"][0]  # year image_names = [] age = [calc_age(photo_taken[i], dob[i]) in range(len(dob))] print(age)  image_name_arg in range(image_names_array.shape[0]):     try:         os.makedirs(str (age[image_name_arg]))     except oserror:         pass     copy(path_root + "/" + str(image_names_array[image_name_arg][0]),str (age[image_name_arg]))     image_name = image_names_array[image_name_arg][0]     image_names.append(image_name)     print( dict(zip(image_names, age)))

after calculating age, creates folder age folder name , copies image files folder.

however there lots of false negatives in resulting folder. how can able sort out?

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
