Installation seems fine but import-issues

[brunkowacodes]

Hey,
I don't know if someone still reads this, but I'm trying to run this package in python 3.10.

I installed it, via

1. Git clone

2. Inserting a cast to an int in the last function in frechet (line 534..), because it didnt compile:

         while(len(cc)!=1):
         m_i=int(len(cc)/2-1)
         eps = cc[m_i]
         rep = _decision_problem(P,Q,p,q,eps)
         if rep:
             cc=cc[:m_i+1]
         else:
             cc=cc[m_i+1:]
        return eps
   

3. Inserting some requires into pyproject.toml, as in this issue :

      [build-system]
      requires = [
          "setuptools",
          "Cython>=0.27.3",  # Note: sync with setup.py
          "numpy"
      ]
      build-backend = "setuptools.build_meta"
   

4. python setup.py install

5. pip install .

With the changes, the installation seems to work.
But when I try to import the distance module via
import traj_dist.distance as tdist I get the following error:

      (synth_privacy_evaluation) ➜  privacyrisk git:(main) ✗ python example.py
      Traceback (most recent call last):
        File "/Users/alex/PycharmProjects/synth_privacy_evaluation/privacyrisk/example.py", line 12, in <module>
          import privrisk
        File "/Users/alex/PycharmProjects/synth_privacy_evaluation/privacyrisk/privrisk.py", line 10, in <module>
          import traj_dist.distance as tdist
        File "/Applications/anaconda3/envs/synth_privacy_evaluation/lib/python3.10/site-packages/traj_dist/distance.py", line 3, in <module>
          from .cydist.sspd import c_e_sspd, c_g_sspd
        File "traj_dist/cydist/sspd.pyx", line 8, in init traj_dist.cydist.sspd
      ModuleNotFoundError: No module named 'basic_euclidean'

I tried to change the imports and add paths manually, but that didn't work either. So if you could help me, that would be really nice!

Hello, I faced the same issue and solved it. It seems that if you are using Python 3, you need to import like this:

from .basic_euclidean import c_point_to_trajectory

instead of

from basic_euclidean import c_point_to_trajectory

https://copyprogramming.com/howto/module-not-found-error-when-importing-a-cython-pyd-file

So, in sspd.pyx and all other .pyx files in cydist directory, just add a dot . before every basic_euclidean and basic_geographical import.
Hope this helps.
