Python error : AttributeError: 'module' object has no attribute 'heappush' -


i trying simple programs involve multiprocessing features in python.

the code given below:

from multiprocessing import process, queue  def print_square(i):   print i*i  if __name__ == '__main__':   output = queue()   processes = [process(target=print_square,args=(i,)) in range(5)]    p in processes:     p.start()    p in processes:     p.join()

however, gives error message attributeerror: 'module' object has no attribute 'heappush'. complete output upon executing script given below:

 traceback (most recent call last):   file "parallel_3.py", line 15, in      output = queue()   file "c:\users\abc\appdata\local\continuum\anaconda2\lib\multi processing\__init__.py", line 217, in queue     multiprocessing.queues import queue   file "c:\users\abc\appdata\local\continuum\anaconda2\lib\multi processing\queues.py", line 45, in      queue import empty, full   file "c:\users\abc\appdata\local\continuum\anaconda2\lib\queue .py", line 212, in      class priorityqueue(queue):   file "c:\users\abc\appdata\local\continuum\anaconda2\lib\queue .py", line 224, in priorityqueue     def _put(self, item, heappush=heapq.heappush): attributeerror: 'module' object has no attribute 'heappush'

the code compiles fine if output=queue() statement commented. possibly causing error ?

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
