python - trouble invoking concurrent.futures job in parallel -

-

मेरा कोड इस प्रकार है। 

  निष्पादक = समवर्ती.फुटेश। थ्रेडपूल एक्सपेक्टर (अधिकतम_वर्कर्स = 4) सीजी के लिए self.parent_job.child_jobs: executor.map (cj.runCommand ())   
 def runCommand (self): os.system (self.cmd_line) सत्यापित करेंऑप्टपुटफ़ाइलें ()। ..  
 रन कॉमांड को सभी बच्चे के लिए समानांतर में क्रियान्वित करने की जरूरत है। इसके अलावा एक ही समय में एक ही बच्चा को चलाया जा सकता है।  
 लेकिन रन कॉमांड को एक बार में केवल एक बार लागू किया जाता है। लेकिन मुझे इसकी आवश्यकता है कि एक ही समय में सभी बाल नौकरियों के लिए आवेदन किया जाए।  executor.map  एपीआई को देखो   
 
 
 इसको प्राप्त करने में कोई भी मदद की सराहना की जाती है। आपने कोड को कॉल करके गलती की और इसके परिणाम को  map  पर भेज दिया;) यही कारण है कि आपका कोड एक बार चला।  
 आपको अलग फ़ंक्शन बनाने की ज़रूरत है जिसे ऑब्जेक्ट्स पर आपकी विधि कहा जाएगा  runCommand  जैसा कि आप  lambda x: x.runCommand ()  (सामान्य रूप में लैम्ब्डा) पास नहीं कर सकते  executor.map  के तर्क के रूप में नहीं कर सकते।  
  def runCommand (cj): वापसी cj.runCommand () l = निष्पादक.मैप (runCommand, self.parent_job.child_jobs)   
 सभी काम तक इंतजार करने के लिए पूरा करने के लिए आपको जनरेटर  l  का मूल्यांकन करना होगा तो आप  w = सूची (एल)  और  w  में परिणाम कर सकते हैं

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
