'em running a python code, but in python code 'em facing problem with these lines of code

import trajoptpy
import trajoptpy.kin_utils as ku
from trajoptpy.check_traj import traj_is_safe, traj_collisions
import trajoptpy.math_utils as mu

actually the main error is importing trajopt as
ImportError: No module named trajoptpy

I have downloaded the github package of trajopt but after compiling I don't know PYTHONPATH is making problem or other dependency in my PC I have set the path as

mudasser@mudasser-PC:~$ export PYTHONPATH=$PYTHONPATH:/home/mudasser/trajopt
mudasser@mudasser-PC:~$ export PYTHONPATH=$PYTHONPATH:/home/mudasser/trajopt/build/lib

now while ctest and running the python code it is making problem for me. ctest error is given as

Errors while running CTest

can someone help me to fix trajopt problem?

It would be easier to help if you pasted the verbose output of ctest. Next time run 'ctest --verbose' and paste the output.

trajopt.txt
I am facing the same issue. I had run ctest -V and attached its result as a file.

Check PYTHONPATH and make sure you've added the source folder and the lib folder to PYTHONPATH.

[k-maheshkumar]

yes, I did. Thank you. Now it's working, but still few tests didn't pass through.
Here is the log file for the same,
trajopt1.txt

What version of SymPy do you have installed?
