_resampler.so: undefined symbol

[animesh]

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 :)

[thesilencelies]

I checked out the 1.1 branch of tensorflow in the one in the sonnet tree, compiled tensorflow from that (which works), then rebuilt sonnet. However I still get the above error for _ZN10tensorflow8internal21checkOpMessageBuilder9NewString. I had the warning mentioned in #16 during build.
I guess I did something wrong, but I'm a little unsure how to implement the solution mentioned above...

I have the same problem as @thesilencelies. I did a git pull in sonnet/tensorflow after which I followed the sonnet installation instructions, but I still get the _resampler.so: undefined symbol error

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.

I again faced this issue on another machine. I downgraded to Python2.7 and made a re-installation attempt which seems to have worked. So I would suggest to check the Python version, seems like Python3 compatibility is less polished... Regards, Ani

@animesh I faced the same error and followd your ways , but I still get the _resampler.so: undefined symbol error .I guess that there might some steps were wrong in this process.

[animesh]

yeah i can imagine, there are many gotchas in setting this beast... for starter, what is your environment like? things like operating system, java, python, tensorflow and bazel versions? are you able to run everything else except sonnet?

[llbuaa2015]

use tensorflow 1.1.0-rc2 replacing the sonnet/tensorflow if 1.1.0-rc2 is used and
bazel build --config=opt --genrule_strategy=standalone --spawn_strategy=standalone :install
this works for me !

[thesilencelies]

PFCM's solution worked for me.

[urosjarc]

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

[hyperji]

@PFCM Cool! I have installed sonnet almost 10 times, all failed, untill now. thank you.

Anyone still having trouble - please see #56 - there are preliminary Wheel files available on PyPI. Please try to install and let us know how you get on.
