Hello, after install according README, I got:

from warpctc_pytorch import CTCLoss Traceback (most recent call last): File "", line 1, in File "/usr/local/lib/python3.7/site-packages/warpctc_pytorch-0.1-py3.7-linux-x86_64.egg/warpctc_pytorch/init.py", line 6, in from ._warp_ctc import * ImportError: dynamic module does not define module export function (PyInit__warp_ctc)

pytorch version 1.0.0, and python3.7

Solved. use pytorch's cpp extension method

i meet the same problem with you, can you tell me more about how to solve this problem? and more about how to use pytorch's cpp extension method, thx

Python has its c++ method, while pytorch have pytorch's own method. in pytorch_binding/setup.py, change as following: ` setup( name='warpctc', ext_modules=[

apparently pybind does not support submodules like warpctc._warpctc

    CppExtension('warpctc._warpctc', ['src/_warpctc.cpp'],
                 include_dirs=['../include'],
                 library_dirs=['build/lib'],
                 libraries=['warpctc'],
                 extra_link_args=[make_relative_rpath('lib')])
],
packages=find_packages(exclude=['tests']),
package_data={'warpctc': ['lib/libwarpctc' + shared_object_ext()]},

cmdclass={
    'build': Build,
    'build_deps': BuildDeps,
    'build_ext': BuildExtension,
    'clean': Clean,
})
