i trying parallelize code have tensorflow model run on multiple gpus. reason, code wrote parallelize training works standard deep neural net, throws errors when using convolutional neural net. here code compute average gradients: def average_gradients(tower_grads): average_grads = [] grad_and_vars in zip(*tower_grads): # note each grad_and_vars looks following: # ((grad0_gpu0, var0_gpu0), ... , (grad0_gpun, var0_gpun)) grads = [] g, _ in grad_and_vars: # add 0 dimension gradients represent tower. expanded_g = tf.expand_dims(g, 0) # append on 'tower' dimension average on below. grads.append(expanded_g) # average on 'tower' dimension. grad = tf.concat(axis=0, values=grads) grad = tf.reduce_mean(grad, 0) # keep in mind variables redundant because shared # across towers. .. return first tower's pointer # variable. v = grad_and_vars[0][1] grad_and_var = (grad, v) average_grads.a

this question has answer here: why use static_cast<int>(x) instead of (int)x? 9 answers is there reason using static_cast on non pointer pod data types, int, float, double? float v = 100; int x = (int) v vs int x = static_cast<int>v is there reason/advantage on using that, saw several answers covers pointers, plain pod data not find explicit answers non-pointers. the best reason i've heard because can grep static_cast , know find casts whereas (int) less specific what's going on in expression. also, c-style casts can remove or add const or volatile , change types without warnings. if try static_cast const pointer/reference type non- const pointer/reference type, compile error.

i'm wondering trying happen in following line. forgive me i'm new python syntax, help! handlers[type(dbw_msg)](dbw_msg) where handlers = secondary: self.secondary_manage.handle.message and dbw_msg = py_from_can(can_msg) where py_from can defined as def py_from_can(can_msg): try: if can_msg.id in py_can_types: return py_can_types[can_msg.id].py_from_can(can_msg) except notimplementederror: pass return none so, without other context, can is: handlers[type(dbw_msg)](dbw_msg) handlers gets subscripted (i.e. square-brackets) type(db_msg) . can assume sort of mapping (a dict ) keys type objects. finally, value returned subcription operation get's called, i.e. () parens. so, handlers mapping type objects callable (e.g. functions). so, example: >>> handlers = {int: lambda x: x**2, str: str.upper} >>> = 8 >>> b = 'foo' >>> handlers[type(a)](a) 64 >>> handlers[type(b)](b)

there previous posts discussing how add username devise model. unfortunately, these posts not discuss how setup views. mainly, i'm interested in updating devise/registrations/edit.html.erb file. in it, have added following lines <div class="field"> <%= f.label :username %><br /> <%= f.text_field :username %> </div> to allow users update username. unfortunately, when save form, username not update. why happening? i checked comment above, if want update user can use user controller (not device registration) , below code user controller class userscontroller < applicationcontroller def edit @user = user.find(params[:id]) end def update # devise if params[:user][:password].blank? params[:user].delete(:password) params[:user].delete(:password_confirmation) end @user = user.find(params[:id]) if @user.update_attributes(user_params) flash[:success] = 'user changed'
