ImportError: No module named _fmm

[littletailee]

Dear Can,

Thank you for sharing the amazing work!

I have an ImportError. I installed FMM in Anaconda python 2.7.15, using Cygwin under Windows 10. I have successfully installed fmm but when using it, I encountered an ImportError as follows:

jwzha@xxx /cygdrive/d/xxxs/MapMatch/fmm_conda/fmm/build $ python Python 2.7.15 (default, Mar 5 2020, 14:56:45) [MSC v.1500 64 bit (AMD64)] on wi n32 Type "help", "copyright", "credits" or "license" for more information.

import fmm Traceback (most recent call last): File "", line 1, in File "C:\Users\jwzha.conda\envs\fmm\lib\site-packages\fmm.py", line 15, in <m odule> import _fmm ImportError: No module named _fmm

The cmake .. returns the following:

I wonder what causes this error. Thank you in advance!

I have not tried with conda on Windows. Conda should also be installed inside the cygwin. If you install conda directly for windows I don't think it will work.

Hi Can,

Thanks for your quick reply! I've succeeded with python2.7 using ubuntu virtual machine.

Best, Jasmine

Thank you for this notice. I think it is better to add a suggestion for installation in ubuntu VM on Windows platform.
