error while running extract_concepts

[JaveedSpritle]

I tried to run the sample input. I used MetaMaplite. I got the following error when using extract_concepts().

File "/usr/local/lib/python3.6/dist-packages/pymetamap-0.2-py3.6.egg/pymetamap/SubprocessBackendLite.py", line 102, in extract_concepts
    with open(output_file_name) as fd:
FileNotFoundError: [Errno 2] No such file or directory: '/tmp/tmpey8rfuom.mmi'.

Can you please help? Thanks.
