python - Getting an array from collections ordereddict for the maximum key, values - 


d = collections.ordereddict() d {'a': array([[ 29.503],        [ 31.829],        [ 13.078],        ...,         [ 43.227],        [ 53.028],        [ 43.928]]),  'b': array([[  28.738],        [  68.151],        [  49.02 ],        ...,         [ 296.73 ],        [ 107.052],        [  87.845]]),  'c': array([[ 11.288],        [ 31.343],        [ 71.269],        ...,         [ 92.106],        [ 34.668],        [ 41.614]])}

if want maximum of each value of array a[0], b[0] & c[0], a[1], b[1] & c[1], ...etc. , return array [a, b, c..., b] etc.

then use y = max(d.iterkeys(), key=lambda k: d[k])

then says,

valueerror: truth value of array more 1 element ambiguous. use a.any() or a.all()

so seek if can array [a, b, c..., b] etc.?

thank you

something this:

np.array(list(d.keys()))[np.hstack(d.values()).argmax(axis=1)]  #array(['a', 'b', 'c', 'b', 'b', 'b'],  #      dtype='<u1')

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...

ios - Change Storyboard View using Seague -

i have following code checks connection server, , depending on want change views if no connection found. nsstring *connect = [nsstring stringwithcontentsofurl:[nsurl urlwithstring:@"http://myserver.com"] encoding:nsutf8stringencoding error:nil]; if (connect == null) { [self performseguewithidentifier:@"network_failure" sender:self]; } else { // other code here } my problem not change views. have added storyboard segue between 2 views identifier of network_failure . not have navigation controller or that, problem? thanks help! no not problem. first of all, in objectivec exists nil object oriented null . must use that. so: if(connect == nil) or better: if(!connect) so due fact nil not same of null , probably code does't enter in if scope . you have been able discover breakpoint. anyway: be sure set trigger segue (line) 2 view controller , , name network_failure (that not best name. should instead view1toview2 ) as, m...
