ImportError: No module named _emd

[bwang482]

Why is that I keep getting "ImportError: No module named _emd" error from emd.py? I use python 2.7.

May I ask what is '_emd' ? I assume it's not the same as pyemd?

Thanks in advance for your time!

I've got the same issue. I traced back to wmd.py, it turned out that the Python.h is not found in emd.h. Someone could help?

me too.

wmd> python wmd.py SMERP_only_text.pk SMERP_only_text_wmd.pk
Traceback (most recent call last):

you can use pyemd instead, which gensim using this package too.
pip install pyemd

[zimengq]

you should first build emd in python-master-emd

Has anyone come across a solution to this? When I run build in python-emd-master, I get the error
Linking wrapper library '_emd.so'. -n ld -shared -o _emd.so emd.o emd_wrap.o ld: unknown option: -shared make: *** [_emd.so] Error 1 rm emd_wrap.o emd.o emd_wrap.c
So it looks like emd isn't being built properly

I've installed swig and build emd with 'make' command
but it still gives the error

ImportError: No module named _emd
