bazel - OSX Tensorflow + Opencv: Symbol Not Found, expected in Flat Namespace -


i use osx10.12, try use opencv in tensorflow, use first method mentioned in question.

i build code there questions following when execute it:

dyld: lazy symbol binding failed: symbol not found: __zn2cv6string8allocateem referenced from: /users/philokey/practice/github/tensorflow/./bazel-bin/tensorflow/examples/test_cv/test_cv expected in: flat namespace

the build file following:

cc_binary( name = "test_cv", srcs = [     "test_cv.cc", ], deps = [     "@opencv//:opencv", ], )

how can solve problem?

you need make sure updated following files under tensorflow directory, correctly:

in workspace - (./tensorflow/tensorflow/workspace) add following: 

new_local_repository(   name = "opencv",   path = "/usr/local/",   build_file = "opencv.build", )

opencv.build - (./tensorflow/tensorflow/opencv.build) add following:

cc_library(   name = "opencv",   srcs = glob(["lib/*.dylib*"]),         <<<<<<<   hdrs = glob(["include/**/*.hpp"]),   includes = ["include"],   visibility = ["//visibility:public"],   linkstatic = 1, )

[note] different operating systems, different dynamic libraries created, example:

  1. linux -> *.so,
  2. windows -> *.dll, and
  3. on osx -> *.dylib

even if face problems please set dyld_print_library environment variable check if correct libraries linked, @ times different versions of libraries may keep busy.

python - How to insert QWidgets in the middle of a Layout? -

Image
i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
