Import error - Githubissues

I'm trying to install this library on custom Docker image. But It shows below error.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/miniconda/envs/py36/lib/python3.6/site-packages/torch_baidu_ctc/__init__.py", line 4, in <module>
    import torch_baidu_ctc._C as _torch_baidu_ctc
ImportError: /miniconda/envs/py36/lib/python3.6/site-packages/torch_baidu_ctc/_C.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZN2at19UndefinedTensorImpl10_singleton

Below is my docker file.
