DLL not found on Windows7 / Canopy32 using binary installer

[David Brown]

I have been trying to install scikit-fmm  using the binary installer for windows.  The installer does not report errors.  When I try to import skfmm, I get an error:

      1 import numpy as np

----> 2 from cfmm import cFastMarcher

      3 from sys import float_info

      4 

      5 FAR, NARROW, FROZEN, MASK = 0, 1, 2, 3

ImportError: DLL load failed: The specified module could not be found. 

I have tried to compile from source, but see compiler errors in my (untested) setup after installing MS VS C++ Express 2008.

The compiler error messages are shown below.  Any tips on getting scikit-fmm to install on Windows / Canopy (32 bit) are appreciated.

David,

Thanks for the email. I have not seen this error after installing the
windows executable, but I have seen this error when trying to "import
skfmm" from inside the skfmm source directory.

I have not used Canopy, it may install packages in a different
location? This website:
https://support.enthought.com/entries/23389761-Installing-packages-into-Canopy-User-Python-from-the-OS-command-line
has some information, but it does not say if Windows binary installers
work with Canopy.

Last week I merged a pull request from Ján Margeta which fixes the
build for MSVC:
https://github.com/scikit-fmm/scikit-fmm/commit/f2e0563ccf2c9d981578c990f3d856c665e48a1d
so you could try building the latest code from github.

If all else fails, you should be able to open the installer executable
with 7-zip and extract the dll (.pyd file) and try to install it
manually?

Let me know how you get on,
Jason

Jason,

Thanks very much for the suggestions and link.  I have not sorted out why the binary installer does not work for me, but I was able to compile from source now using the latest scikit-fmm version from Github.  It works as expected now on the 32-bit Canopy python 2.7 setup. Your timing is great!
