module 'scikits.odes' has no attribute 'test' #164
Description
I assume there's an issue with pathing but I cannot seem to fix it.
Following the guide on https://scikits-odes.readthedocs.io/en/stable/installation.html, I installed sundials 5.1.0 using the command
cmake -DLAPACK_ENABLE=ON -DSUNDIALS_INDEX_SIZE=64 ..
inside a build directory that I created in the source folder (note that I do not specify an install path such that sundials is properly installed into /usr/local/lib and /usr/local/include).
Then, I install scikits.odes via pip. I also installed nose as is mentioned in the guide.
Running od.test() however outputs
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
Cell In[2], line 1
----> 1 import scikits.odes as od; od.test()
AttributeError: module 'scikits.odes' has no attribute 'test'
Also, trying to use the solver returns an error:
import numpy as np
from scikits.odes import ode
tout = np.linspace(0, 1)
initial_values = np.array([1, 0])
omega = 6.0
def example1(t, y, ydot):
ydot[0] = x[1]
ydot[1] = - omega * x[0]
pass
solver = ode('cvode', example1, old_api=False)
solution = solver.solve([0.,1.,2.], initial_values)
Output:

ValueError: Integrator name cvode does not exist
The libraries however do exist. What am I missing here?
Also, apparently the guide is out-of-date seeing that sundials 6 is supported as well. Will there be an update?
