build a .exe for Windows from a python 3 script importing theano with pyinstaller -


edit september, 2, 2017, 1pm

i managed build .exe pyinstaller after many episodes.

unfortunately failed deal ‘theano’ module (that required in case ‘pymc3’ module) , had modify .py files , give part of application. description below has 2 aims: first may help; second could me building .exe windows 7+, ‘theano’ module ?

reminder: python 3 script opens simple gui made qt designer in ‘.ui’ file , imports pyqtgraph (with pyqt5), pymc3 (and theano required pymc3), scipy, numpy, os, sys. distributed on machines windows 7+. tried build ‘.exe’ py2exe, cx_freeze, pynsist , pyinstaller (i opened , updated several posts, 1 still opened: build .exe windows python 3 script importing pyqtgraph , opening gui) failed. best result (with pyinstaller) described below after had give theano.

  • the command line ended is: pyinstaller —noupx —onefile —add-data “toto.ui;.” toto.py. strangely:

1 qt designer file ‘toto.ui’ not included , must distributed .exe. otherwise there error message when running .exe saying toto.ui not found;

2 ‘platforms’ directory ‘library/plugin’ directory of python environment must distributed along .exe. otherwise there error message when running .exe ‘this application has failed start because not find qt platform plugin windows’ (but there no error message pyinstaller when building !)

3 .exe 220mb big ! seems pyinstaller includes bunch of useless things during building.

  • pyqtgraph problem:

at first sight, module ‘pyqtgraph’ seems incompatible pyinstaller. indeed, when python code imports pyqtgraph, pyinstaller gives syntaxerror: ‘yield’ inside async function. seems me awkward (is bug in pyinstaller ?) because had impression forums related asynchronous generators compatible python 3.6, while pyinstaller works python 3.5- not compatible asynchronous generators… why pyinstaller use ? turns out bug-like feature disabled in new version of pyinstaller not released (and not installed default): pip install git+https://github.com/pyinstaller/pyinstaller, 9dogs (in comments). found may explicitly write os.environ[‘pyqtgraph_qt_lib'] = 'pyqt5’ or ‘pyqt4’ before importing pyqtgraph in py file(s)

  • theano problem:

theano turns out make several implicit imports not detected pyinstaller. building looks ok when running .exe error messages ‘no module theano.tensor.shared_randomstreams’. unfortunately failed use '--hidden-import' option of pyinstaller added explicitly imports in py file(s) (in example ’import theano.tensor.shared_randomstreams’ ).

but not end: after that, file ‘…\appdata\local\temp_mei35682\theano\gpuarray\blockgemv.c' missing, leading [4128] failed execute script. don’t know file , didn’t find information. gave , removed part of gui avoid theano. can me using theano pyinstaller ?

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
