Undefined symbol when loading module

See original GitHub issue

Hi, I’m trying to use warp-rnnt, but I get the error mentioned below. My environment:

Python: Python 3.7.5
Torch: 1.8.0+cu111
CUDA Version: 11.2

Output of python -m warp_rnnt.test

Traceback (most recent call last):
  File "/usr/lib/python3.7/", line 183, in _run_module_as_main
    mod_name, mod_spec, code = _get_module_details(mod_name, _Error)
  File "/usr/lib/python3.7/", line 109, in _get_module_details
  File "/home/martynas/.../lib/python3.7/site-packages/warp_rnnt/", line 2, in <module>
    import warp_rnnt._C as core
ImportError: /home/martynas/.../lib/python3.7/site-packages/warp_rnnt/ undefined symbol: _ZN6caffe28TypeMeta21_typeMetaDataInstanceIN3c107complexIfEEEEPKNS_6detail12TypeMetaDataEv

Is there anything I can do?
