No module named _C

🐛 Bug

While running the command, pytest test/test_cpp_api_parity.py -k Loss -v, I am getting the following error:

ImportError while importing test module '/home/ankit_jha/test/pytorch/test/test_cpp_api_parity.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:
test/test_cpp_api_parity.py:10: in <module>
    import torch
torch/__init__.py:81: in <module>
    from torch._C import *
E   ImportError: No module named _C

I have build PyTorch in develop mode. I have to push some changes to C++ Frontend. Since, I am new to PyTorch, I am not sure if it's because of my environment or if it is a bug.

• OS (e.g., Linux): Ubuntu 18.04
• How you installed PyTorch (conda, pip, source): pip
• Build command you used (if compiling from source): python setup.py develop
• Python version: 3.6

You could try running the test from another directory, this sometimes happens if there is a file named torch.py or (more likely in this case) a folder named torch/ with an __init__.py inside, then import torch tries to import that directly instead of the installed/symlinked version in your Python's site-packages.

Something might be getting installed incorrectly, the import my_module resolution rules can be found here.
