Hi! Comparing the values of DTW (with euclidean distance) from traj-dist and tslearn library, weren't the values supposed to be the same?
Thanks in advance.
hi. i'm trying to install the package but when running setup.py in pycharm i got this error:
C:\Users\user\AppData\Local\Programs\Python\Python38\lib\distutils\dist.py:274: UserWarning: Unknown distribution option: 'download_urt' error: no commands supplied
does anybody know how to fix it?by the way is there a way to run this package in browser notebooks like jupyter?
Hey, great job but is there a way to avoid this error on windows ?
Thanks !

Hello, I have tryed to run your code on Windows and I always get the same error, "ModuleNotFoundError: No module named 'setuptools'"
Of course I have an upgraded setuptools package but still I get the error message.
Here the commans I used:
pip install NumPy Cython shapely geohash2 pandas scipy # To be sure about the requirement--> all ok
pip install setuptools # all ok
pip install setup.py #--> all ok
pip install . # -->ERROR: Exception:... ModuleNotFoundError: No module named 'setuptools'
I hope you can help me. Thanks a lot.
My python version--> python 3.8.2
My pip -version--> pip 20.1.1 from c:\users\usuario\appdata\local\programs\python\python38\lib\site-packages\pip (python 3.8)
this file is not :
data/extracted/starting_from/Caltrain_city_center_v3.pkl
Could you share it?
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
Git clone
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
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"
python setup.py install
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

File "traj_dist/cydist/sspd.pyx", line 8, in init traj_dist.cydist.sspd

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!
Hi! I'm trying to run the examples using python 3, and I'm getting the following error:
[silencer@myhostname traj_dist]$ python example.py
Traceback (most recent call last):
File "example.py", line 2, in <module>
import traj_dist.distance as tdist

from cydist.sspd import c_e_sspd, c_g_sspd
ModuleNotFoundError: No module named 'cydist.sspd'
I have installed it as per the readme file. It is working in python 2, however.
Do you have any idea about what could be happening? I'd like to use this library with python 3.
Thank you for your hard work!

Thank you for your help.
Hi and thanks for such a good work.
I'm having troubles when I try to import traj_dist.distance as tdist. I get this error:
ModuleNotFoundError: No module named 'traj_dist.cydist.sspd'
do you know what is the problem?
I made the follow process to install the package:
Here what I got:
import traj_dist.distance as tdist2
File "/home/equipo/Documentos/traj-dist-master/traj_dist/distance.py", line 3, in
from .cydist.sspd import c_e_sspd, c_g_sspd
ModuleNotFoundError: No module named 'traj_dist.cydist.sspd'
could you give me a light with this?
Thanks!
Would be great to multithread the cdist computation using something like joblib.
I have successfully ran
python setup.py install
and
pip install .
But faced import error like it:
ImportError: cannot import name 'c_e_sspd' from 'traj_dist.cydist.sspd' (unknown location)
Could you please give me any solution?
Thank you very much!

From earlier issues - it seems Python 3 is not supported. But I am installing it in an environment with Python 2.7.5 still gives the above error. Please help to resolve the same.
Hello,
Can someone please help me run the program located at: https://github.com/bguillouet/traj-dist
So I followed the instructions and did this:
So if anyone can help me out here and help to run this python project, I would highly appreciate it.
I think there is a problem in the initialization of C, where:
C[1:, 0] = sum(gt0_dist)
C[0, 1:] = sum(gt1_dist)
It should be:
j = 1
sum = 0
for i in gt0_dist:
sum += i
C[j, 0] = sum
j += 1
Same to the C[0, 1:]
I observe on code the eps (ε) is set to 200 for LCSS.
Let's assume a dataset with human trajectories like Geolife. I want to measure the similarity of two random trajectories from this dataset using the EDR or/and LCSS algorithm(s).
I wonder, which factors to consider in order to define the value of spatial distance threshold ε used by EDR and LCSS?
I suppose that if I use a different dataset, like Hurricanes or Animals movements, this threshold should be different as the movement pattern is different. The speed of a hurricane is different than the speed of a walking human.
Also, the sampling rate is something to take into consideration?
Hello,
Can someone please help me run the program located at: https://github.com/bguillouet/traj-dist
if you want to contact me, contact me at: [email protected]
So I followed the instructions and did this:
Navigate to the folder where traj-dist is
python setup.py install
pip install .
After this I don't know how to proceed, I went into traj_dist folder and tried to run every python file, but I kept getting an error every time.
So if anyone can help me out here and help to run this python project, I would highly appreciate it.
When I run pip install .
, I come across the following error
