grpc python installation from source

[mat...@lefty.io]

Hello,

I have cloned the grpc github directory in /opt and built and installed the cpp code from source.
I then installed the python code with CONFIG=opt tools/run_tests/build_python.sh 2.7
I did that a few months ago and it created a python2.7_virtual_environment in my grpc directory
I then used the python bin from this directory to use grpc in python.

The problem is, after updating the source to HEAD at master branch, the installation for python doesn't seem to to work anymore.

I did a git pull && git submodule update --init && make clean && make && make install for the cpp code, that works fine.
I did a CONFIG=opt tools/run_tests/build_python.sh 2.7 for the python code but I had still error when trying to run grpc python code.
ImportError: /opt/grpc/python2.7_virtual_environment/local/lib/python2.7/site-packages/grpc/_adapter/_c.so: undefined symbol: grpc_composite_credentials_create

For clarity I renamed the python2.7_virtual_environment directory with _old and redid a CONFIG=opt tools/run_tests/build_python.sh 2.7
It did not create the virtual environment directory it used to create.

I don't know if this is normal ? If so, how to use grpc python code ?
If not, how could I make it work ?

Thanks in advance for any pointers

Here is the output summary of the command CONFIG=opt tools/run_tests/build_python.sh 2.7 :

I suspect that this is due to incompatibilities between the core you installed months ago and the Python extension code built from HEAD. Does the problem persist if you rebuild and reinstall the C++ code from the same HEAD?

Hi
Thank you for your answer.

When I do a git pull and git submodule update --init, both cpp and python should be at the HEAD right ?
That's what I did before getting stuck.

For clarity I did a clean install in a VM.

cd /opt
git clone https://github.com/grpc/grpc.git
cd grpc
git submodule update --init
cd /opt/grpc/third_party/protobuf
./autogen.sh
./configure
make
make install
cd /opt/grpc
ldconfig
make
make install

Then:
CONFIG=opt tools/run_tests/build_python.sh 2.7
In the output of this command I didn't see errors but maybe I'm missing something ?

It didn't create a python2.7_virtual_environment directory in $GRPC_ROOT

So how am I supposed to use grpc in python ? According to the run_server.sh in examples/python/route_guide/ there should be such a directory.

The end of the output is pasted below:

Hi
Yes, the problem persists.
Actually even with a new ubuntu 14.04 vm I can't get the python2.7_virtual_environment directory.
Is this related to the use of tox ?
Best,
Mathias

Hi Nathaniel,

Correct me if I'm wrong,

It appears that tools/run_tests/build_python.sh was changed recently to use tox

and that's what broke (the virtual environment is not installed anymore, at least not

in the same way).

We have had success by not using tools/run_tests/build_python.sh but just setup.py install directly...
