pydist and windows support

[Neabfi]

Hey, great job but is there a way to avoid this error on windows ?
Thanks !

Hi Neafbi, and Thank you!.

I really have no experience in Windows, Hence I can't reproduce your error and i have no clue about how to solve it :(

I had the same issue building with Python3, make sure you're building with Python2.

Hey Guys,
I figured out a way for making the code usable on python3.

Simple steps:

The old Geohash lib doesn't seem to work with python3 no more, I have replaced it with geohash2 and edited the code in the file traj_dist/pydist/linecell.py from:

import Geohash.geohash as geoh

to:

import geohash2 as geoh

Also, in setup.py I replaced the requirement to geohash2.

Use 2to3 script to get python3 ready code:

 2to3 --output-dir=traj-dist-py3 -W -n traj-dist

Copy the pyx files over from the original package in the cydist dir to the cydist dir under the new traj-dist-py3/traj_dist dir

From the traj-dist-py3 directory build the extensions and then a wheel file using:

python setup.py build_ext --inplace --force
python setup.py bdist_wheel

And finally install using pip and the newly created wheel file - looks like this:

pip install traj_dist/trajectory_distance-1.0-cp36-cp36m-macosx_10_9_x86_64.whl

I also figured out a way to solve this problem, I uesd python 3.6.1 32bit. I checked “distance.py” when I met the error"No module named 'pydist'". Then I made the following changes :"
from pydist.linecell import trajectory_set_grid
from cydist.sspd import c_e_sspd, c_g_sspd
from cydist.dtw import c_e_dtw, c_g_dtw
from cydist.erp import c_e_erp, c_g_erp
from cydist.edr import c_e_edr, c_g_edr
from cydist.lcss import c_e_lcss, c_g_lcss
from cydist.hausdorff import c_e_hausdorff, c_g_hausdorff
from cydist.discret_frechet import c_discret_frechet
from cydist.frechet import c_frechet
from cydist.sowd import c_sowd_grid"
changed into
"
from traj_dist.pydist.linecell import trajectory_set_grid
from traj_dist.cydist.sspd import c_e_sspd, c_g_sspd
from traj_dist.cydist.dtw import c_e_dtw, c_g_dtw
from traj_dist.cydist.erp import c_e_erp, c_g_erp
from traj_dist.cydist.edr import c_e_edr, c_g_edr
from traj_dist.cydist.lcss import c_e_lcss, c_g_lcss
from traj_dist.cydist.hausdorff import c_e_hausdorff, c_g_hausdorff
from traj_dist.cydist.discret_frechet import c_discret_frechet
from traj_dist.cydist.frechet import c_frechet
from traj_dist.cydist.sowd import c_sowd_grid
"
add the modle name"traj_dist"
