c++ - Constructor inheritance for class derived from template class in visual studio 2015 rc -

-

according page of msvs2015rc new features constructor inheritance should supported. yes, works in simple cases this:

struct b {      b(int) {} }; struct d : b {     using b::b; // can create d object b's constructor  };

but if i'll try create more complex example:

template <class t> struct b {     b(int) {}  };  template <template <class> class c, class t> struct d : c<t> {     using c<t>::c; };  int main() {      d<b,int> d(42);     return 0; }

i've got compiler errors:

  • error c2039: 'c': not member of 'b<t>'
  • error c2873: 'c': symbol cannot used in using-declaration
  • error c2664: 'd<b,int>::d(d<b,int> &&)': cannot convert argument 1 'int' 'const d<b,int> &'

i can eliminate these errors if , if rename template template class c b:

template <template <class> class b, class t> struct d : b<t> {     using b<t>::b; };

i think compiler bug because of these codes compiled gcc/clang.

do has opinion issue?

it bug in msvc , appears in latest version provide online. so, please, submit bug report. relevant discussion might found in other question. contains excerpts standard explain why should work.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl

python - PyCharm Type error Message -

i'm newbie trying out ml/dbn in python (3.4) under pycharm (comm.ed 4.5). following definition def make_thetas(xmin,xmax,n): xs = np.linespace(xmin,xmax,n) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1] + widths return thetas throws error "class 'tuple' not define ' sub ', '-' operator cannot used on instance" on - operator on third line (widths = ....) ideas on how code running under pycharm - works alright in interactive python window. thx. to all, after g'g lot have found workaround seems work within pycharm. workaround because (even python newbie) expected python not need explicit typecasting, not when using datatypes imported lib such numpy. def make_thetas(xmin,xmax,n): xs = np.array(np.linspace(xmin,xmax,n)) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1]+ widths return thetas using docstrings type-hinting such below did not work def make_thetas(xmin,xmax,n): "&q
