Segmentation fault

My config:

Anaconda 2 + tensorflow (no gpu) / Ubuntu 16.04

I assemble sonnet as specified, except I build with following flag:

bazel build --config=opt :install --copt=“-D_GLIBCXX_USE_CXX11_ABI=0”

I use this flag. because otherwise I get following error:

NotFoundError: /home/kovalenko/anaconda2/lib/python2.7/site-packages/sonnet/python/ops/_resampler.so: undefined symbol: _ZN10tensorflow8internal21CheckOpMessageBuilder9NewStringB5cxx11Ev

Following code causes error Segmentation fault:

import numpy as np
import sonnet as snt
import tensorflow as tf

image = np.ones((1, 100, 100, 3))
image[0, 50, :, :] = 0
image[0, :, 50, :] = 0

shift = np.ones((100, 100, 2))
shift[:, :, 1] = 0
shift = np.expand_dims(shift, 0)

res = snt.resampler(tf.Variable(initial_value=image), tf.Variable(initial_value=shift))

init_op = tf.global_variables_initializer()
sess = tf.Session()
sess.run(init_op)

# following line triggers error
x = res.eval(session=sess)

@Tutufa glad you got it sorted - As far as I’m aware we’re not specifying versions of GCC anywhere in the Sonnet repository, but depending on what is installed on your system bazel may pick up mismatching versions. We’ll be updating the install instructions soon to try to cover the issues that people have been having, thanks for providing this information.

Yes, it was gcc version mismatch. Do the following:

1. Compile r1.1 TF from github, install TF
2. Compile Sonnet (switch to r1.1 in tensorflow dir inside sonnet), Install Sonnet

I used gcc 5.*
