[gnnbest]

run python setup.py install is ok but when I ran python setup.py test it had errors:: I used python3 and tensorflow 1.3.0 gpu version

[nickwind]

same issue for me

[chenchu-zs]

similar issue for me, too. tensorflow.python.framework.errors_impl.NotFoundError: /home/shuzhan1/workspace/warp-ctc/tensorflow_binding/warpctc_tensorflow/kernels.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZTIN10tensorflow8OpKernelE

[hookover]

me too ..

[vankrelian]

same

/warp-ctc/tensorflow_binding/warpctc_tensorflow/kernels.so: undefined symbol: _ZTIN10tensorflow8OpKernelE

EDIT1: I found out that this error only occurs with tensorflow 1.4. So, any plans to support tensorflow 1.4 and the upcoming 1.5?

[wellescastro]

Same to me in TF 1.4

[struCoder]

ME TOO...

TF: 1.3.0 python: 3.5

Passing additional

extra_link_args=['-L' + tf.sysconfig.get_lib(), '-ltensorflow_framework']

to setuptools.Extension parameters in setup.py works for me (TF 1.4)

[huizhang0110]

same to me

[gccrpm]

anyone solved this problem? the same: warpctc_tensorflow/kernels.so: undefined symbol: _ZTIN10tensorflow8OpKernelE

[engrean]

Same for me on tensorflow 1.7.0 kernels.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZTIN10tensorflow8OpKernelE I am using anaconda.

[chenchu-zs]

I solved. Add 'tensorflow_framework' to libraries, the issue will be fixed.

ext = setuptools.Extension('warpctc_tensorflow.kernels',
                           sources = lib_srcs,
                           language = 'c++',
                           include_dirs = include_dirs,
                           library_dirs = [warp_ctc_path],
                           runtime_library_dirs = [os.path.realpath(warp_ctc_path)],
                           libraries = ['warpctc', 'tensorflow_framework'],
                           extra_compile_args = extra_compile_args)

[struCoder]

@Sherry-Zhang I installed tensorflow by pip, follow your steps i got this wrong: can not foud -ltensorflow_framework

[chenchu-zs]

@struCoder it only works when you build tensorflow from source

[TheJaeLal]

I built tensorflow 1.7 from source and still getting the same error The 'TENSORFLOW_SRC_PATH' environment variable, should it point to (git cloned) tensorflow source code, or the installed tensorflow directory? @Sherry-Zhang can you tell the exact steps you used?
