Description: gRPC Python Tools
        =================
        
        Package for gRPC Python tools.
        
        Supported Python Versions
        -------------------------
        Python >= 3.5
        
        Deprecated Python Versions
        --------------------------
        Python == 2.7. Python 2.7 support will be removed on January 1, 2020.
        
        Installation
        ------------
        
        The gRPC Python tools package is available for Linux, Mac OS X, and Windows
        running Python 2.7.
        
        Installing From PyPI
        ~~~~~~~~~~~~~~~~~~~~
        
        If you are installing locally...
        
        ::
        
          $ pip install grpcio-tools
        
        Else system wide (on Ubuntu)...
        
        ::
        
          $ sudo pip install grpcio-tools
        
        If you're on Windows make sure that you installed the :code:`pip.exe` component
        when you installed Python (if not go back and install it!) then invoke:
        
        ::
        
          $ pip.exe install grpcio-tools
        
        Windows users may need to invoke :code:`pip.exe` from a command line ran as
        administrator.
        
        n.b. On Windows and on Mac OS X one *must* have a recent release of :code:`pip`
        to retrieve the proper wheel from PyPI. Be sure to upgrade to the latest
        version!
        
        You might also need to install Cython to handle installation via the source
        distribution if gRPC Python's system coverage with wheels does not happen to
        include your system.
        
        Installing From Source
        ~~~~~~~~~~~~~~~~~~~~~~
        
        Building from source requires that you have the Python headers (usually a
        package named :code:`python-dev`) and Cython installed. It further requires a
        GCC-like compiler to go smoothly; you can probably get it to work without
        GCC-like stuff, but you may end up having a bad time.
        
        ::
        
          $ export REPO_ROOT=grpc  # REPO_ROOT can be any directory of your choice
          $ git clone -b RELEASE_TAG_HERE https://github.com/grpc/grpc $REPO_ROOT
          $ cd $REPO_ROOT
          $ git submodule update --init
        
          $ cd tools/distrib/python/grpcio_tools
          $ python ../make_grpcio_tools.py
        
          # For the next command do `sudo pip install` if you get permission-denied errors
          $ GRPC_PYTHON_BUILD_WITH_CYTHON=1 pip install .
        
        You cannot currently install Python from source on Windows. Things might work
        out for you in MSYS2 (follow the Linux instructions), but it isn't officially
        supported at the moment.
        
        Troubleshooting
        ~~~~~~~~~~~~~~~
        
        Help, I ...
        
        * **... see a** :code:`pkg_resources.VersionConflict` **when I try to install
          grpc**
        
          This is likely because :code:`pip` doesn't own the offending dependency,
          which in turn is likely because your operating system's package manager owns
          it. You'll need to force the installation of the dependency:
        
          :code:`pip install --ignore-installed $OFFENDING_DEPENDENCY`
        
          For example, if you get an error like the following:
        
          ::
        
            Traceback (most recent call last):
            File "<string>", line 17, in <module>
             ...
            File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 509, in find
              raise VersionConflict(dist, req)
            pkg_resources.VersionConflict: (six 1.8.0 (/usr/lib/python2.7/dist-packages), Requirement.parse('six>=1.10'))
        
          You can fix it by doing:
        
          ::
        
            sudo pip install --ignore-installed six
        
        * **... see compiler errors on some platforms when either installing from source or from the source distribution**
        
          If you see
        
          ::
        
            /tmp/pip-build-U8pSsr/cython/Cython/Plex/Scanners.c:4:20: fatal error: Python.h: No such file or directory
            #include "Python.h"
                            ^
            compilation terminated.
        
          You can fix it by installing `python-dev` package. i.e
        
          ::
        
            sudo apt-get install python-dev
        
          If you see something similar to:
        
          ::
        
            third_party/protobuf/src/google/protobuf/stubs/mathlimits.h:173:31: note: in expansion of macro 'SIGNED_INT_MAX'
            static const Type kPosMax = SIGNED_INT_MAX(Type); \\
                                       ^
        
          And your toolchain is GCC (at the time of this writing, up through at least
          GCC 6.0), this is probably a bug where GCC chokes on constant expressions
          when the :code:`-fwrapv` flag is specified. You should consider setting your
          environment with :code:`CFLAGS=-fno-wrapv` or using clang (:code:`CC=clang`).
        
        Usage
        -----
        
        Given protobuf include directories :code:`$INCLUDE`, an output directory
        :code:`$OUTPUT`, and proto files :code:`$PROTO_FILES`, invoke as:
        
        ::
        
          $ python -m grpc.tools.protoc -I$INCLUDE --python_out=$OUTPUT --grpc_python_out=$OUTPUT $PROTO_FILES
        
        To use as a build step in distutils-based projects, you may use the provided
        command class in your :code:`setup.py`:
        
        ::
        
          setuptools.setup(
            # ...
            cmdclass={
              'build_proto_modules': grpc.tools.command.BuildPackageProtos,
            }
            # ...
          )
        
        Invocation of the command will walk the project tree and transpile every
        :code:`.proto` file into a :code:`_pb2.py` file in the same directory.
        
        Note that this particular approach requires :code:`grpcio-tools` to be
        installed on the machine before the setup script is invoked (i.e. no
        combination of :code:`setup_requires` or :code:`install_requires` will provide
        access to :code:`grpc.tools.command.BuildPackageProtos` if it isn't already
        installed). One way to work around this can be found in our
        :code:`grpcio-health-checking`
        `package <https://pypi.python.org/pypi/grpcio-health-checking>`_:
        
        ::
        
          class BuildPackageProtos(setuptools.Command):
            """Command to generate project *_pb2.py modules from proto files."""
            # ...
            def run(self):
              from grpc.tools import command
              command.build_package_protos(self.distribution.package_dir[''])
        
        Now including :code:`grpcio-tools` in :code:`setup_requires` will provide the
        command on-setup as desired.
        
        For more information on command classes, consult :code:`distutils` and
        :code:`setuptools` documentation.
