_resampler.so: undefined symbol

faced this error while executing the example code

import sonnet as snt
import tensorflow as tf
snt.resampler(tf.constant([0.]), tf.constant([0.]))

recompiling the tensorflow to 1.1.0-rc2 and replacing the downloaded sonnet/tensorflow with this one solved the problem 😃

~I’m also getting this as per @thesilencelies. Tried tensorflow 1.1.0, then 1.1.0-rc2 when that didn’t work. In both cases ldd on the produced _resampler.so shows:~

        linux-vdso.so.1 =>  (0x00007ffe9c52b000)
        libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f87868d3000)
        libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f87866b5000)
        libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f878632d000)
        libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f8786116000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f8785d4f000)
        /lib64/ld-linux-x86-64.so.2 (0x000055b1b0e70000)

~ie. it doesn’t look as if the op library is being linked to anything tensorflow related? Using bazel 0.4.5 on ubuntu 17.10 if it helps.~

Forget about this.

Fixed it by building Sonnet with

bazel build --config=opt --copt="-D_GLIBCXX_USE_CXX11_ABI=0" :install

I believe the issue was that Tensorflow was being built with GCC 4.x while Sonnet was using the system default which is >= 5.

@PFCM I f****** love you!
