Trouble with installing TDM-GCC/OpenBLAS for Theano on Windows 10 - DLL load failed -


without using c++ compiler setup (see below) works (but slow of course). speed runtime tried install tdm-gcc. import error "dll load failed" shown. after spending hours read installation guides, downloading openblas, experiment, read question/comments "dll load failed" - came no step forward. can me?

installed software:

  • windows 10 home

  • python 3.6.1 (v3.6.1:69c0db5, mar 21 2017, 18:41:36) [msc v.1900 64 bit (amd64)] on win32

  • numpy (1.13.0rc2+mkl) (installed wheel)

  • scipy (0.19.0) (installed wheel)
  • scikit-learn (0.18.1) (installed wheel)
  • theano (0.9.0)

  • keras (2.0.6)

  • gcc version 5.1.0 (tdm64-1)

  • openblas-v0.2.19-win64-int32

i added following entries path:

c:\python36\ c:\tdm-gcc-64\bin\ c:\tdm-gcc-64\x86_64-w64-mingw32\bin\ c:\tdm-gcc-64\x86_64-w64-mingw32\lib\ c:\tdm-gcc-64\lib\gcc\x86_64-w64-mingw32\5.1.0\ c:\tdm-gcc-64\libexec\gcc\x86_64-w64-mingw32\5.1.0\ c:\openblas-v0.2.19-win64-int32\bin\ c:\openblas-v0.2.19-win64-int32\lib\

my theaonrc.txt looks this:

[global] floatx = float32 device = cpu cxx=c:\\tdm-gcc-64\\bin\\g++.exe  [blas] ldflags = -lc:\\openblas-v0.2.19-win64-int32\\bin -lc:\\openblas-v0.2.19-  win64-int32\\lib -lopenblas

i gave up, uninstalled setup , installed anaconda – works :-)

for installing anaconda used guide https://machinelearningmastery.com/setup-python-environment-machine-learning-deep-learning-anaconda/

vue.js - Create hooks for automated testing -

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...

Add new key value to json node in java -

i have json file : { "id":1, "name":"abc", "addressdetails": { "city":"newyork" } } i wanted add 1 more key-value ("pincode" : "414141") node 'addressdetails'. i tried using : objectmapper mapper = new objectmapper(); jsonnode root = mapper.readtree(new file("d://test.json")); objectnode node = mapper.createobjectnode(); node.with("addressdetails").put("pincode", "414141"); but it's not getting added, there way can ? you can try you should modify file path objectmapper mapper = new objectmapper(); objectnode nodes = mapper.readvalue(new file("d:\\test.txt"), objectnode.class); nodes.with("addressdetails").put("pincode", "414141"); mapper.writer().writevalue(new file("d:\\test.txt"), nodes);
