KeyError: 'OPENSMILE_PYTHON'

[skx300]

I am trying to run it. But I got the following error:

Traceback (most recent call last): File "make_arff/test/test_arff.py", line 55, in <module> test_input() File "make_arff/test/test_arff.py", line 48, in test_input data_path = os.environ["OPENSMILE_PYTHON"] File "D:\Program Files\Anaconda3\lib\os.py", line 725, in __getitem__ raise KeyError(key) from None KeyError: 'OPENSMILE_PYTHON'

Also, the usage is quite ambiguous. Could you give a more clear example? especially in Windows.
