python - Nested Bazel Projects -


i'm trying build project uses tensorflow serving, made directory my_dir workspace file, cloned serving repo it, put custom files directory my_project, configured tensorflow within tensorflow_serving, built tensorflow serving my_dir/serving with

bazel build //tensorflow_serving/...

everything builds fine there, try build python file imitating mnist_export , put in my_dir , make build file

py_binary(    name = "export_cnn",    srcs = [        "export_cnn.py",    ],    deps = [        "@tf//tensorflow:tensorflow_py",        "@tf_serving//tensorflow_serving/session_bundle:exporter",    ], )

however, when run 

bazel build //my_project:export_cnn

i following errors:

error:   .../bazel/_bazel_me/3ef3308a843af155635e839105e8da5c/external/tf/tensorflow/core/build:92:1: null failed: protoc failed: error executing command bazel-out/host/bin/external/tf/google/protobuf/protoc '--cpp_out=bazel-out/local_linux-fastbuild/genfiles/external/tf' -iexternal/tf -iexternal/tf/google/protobuf/src ...

in workspace file, have following:

local_repository(   name = "tf",   path = __workspace_dir__ + "/serving/tensorflow", )  local_repository(   name = "tf_serving",   path = __workspace_dir__ + "/serving", )  load('//serving/tensorflow/tensorflow:workspace.bzl', 'tf_workspace') tf_workspace("serving/tensorflow/", "@tf")

my hypothesis because tensorflow sub-sub-project not putting generated files in grandparent-projects bazel-out. however, i've tried many things , haven't been able work.

i have tensorflow serving in folder , project in another. workspace file:

workspace(name = "my_project")  local_repository(   name = "org_tensorflow",   path = __workspace_dir__ + "/tf-serving/tensorflow/", )  local_repository(   name = "tf_serving",   path = __workspace_dir__ + "/tf-serving/", )  load('//tf-serving/tensorflow/tensorflow:workspace.bzl', 'tf_workspace') tf_workspace("tf-serving/tensorflow/", "@org_tensorflow")  # ===== grpc dependencies =====  bind(     name = "libssl",     actual = "@boringssl_git//:ssl", )  bind(     name = "zlib",     actual = "@zlib_archive//:zlib", )

i have copied zlib.build tensorflow serving same place have workspace file.

the build file in project has rule (similar yours):

py_binary(     name = "export_model",     srcs = [         "export_model.py",     ],     deps = [         "@org_tensorflow//tensorflow:tensorflow_py",         "@tf_serving//tensorflow_serving/session_bundle:exporter",     ], )

the difference between code , yours included dependencies in root workspace. code compiling , working fine me in 1 machine have issues compile in others (ubuntu 14.04) because of 1 dependency. hope works you.

5 Reasons to Blog Anonymously (and 5 Reasons Not To)

Google AdWords and AdSense - A Dynamic Small Business Marketing Duo

Unless you have been living under a rock for the last year or so, you probably know that Google has become the king of the search engine hill. There are many reasons for this but number one in my opinion is that above all else they put value on content. Today I want to introduce you to two very powerful small business advertising options created by Google. These two ingenious programs have all but revolutionized the way advertising is done on the web. Warning: If you are thinking..."web advertising isn't for me, I just need a few more clients around the block"...you better read this or be prepared to have your competitors eat your lunch. Goolge AdSense - Again content is king at Google. This program allows web site "publishers" to add some code from Google and receive "content relevant" ads on their site from other site owners. Here is an example - those ads in the box on the right of the page are delivered by Google and are matched to the content
