Pydstool Do Not Recognize Scipy Version

I have installed PyDSTool package : pip install PyDSTool==0.90.2 It return : Requirement already satisfied: PyDSTool==0.90.2 in /usr/local/lib/python2.7/dist-packages/PyDSTool-0.

Solution 1:

The PyDSTool project homepage at sourceforge is down: http://pydstool.sourceforge.net/ points to http://www.ni.gsu.edu/~rclewley/PyDSTool/FrontPage.html that returns "file not found".

The project has moved to GitHub: https://github.com/robclewley/pydstool

There are several issues in line with yours there. The problem is that, currently, the development of SciPy's integrate module has broken the calls from PyDSTool.

One solution: use an older version of SciPy. The alternatives are either to find yourself the points of failure or to use the fork here: https://github.com/tkf/pydstool/tree/tkf

Solution 2:

PyDSTool has a bug in line 76 of __init__.py

The original code is as follows:

if vernums[1] < 5:
    raise RuntimeError("SciPy v0.5.1 or above is required")

I have changed the code like this and then the problem was gone:

if vernums[1] < 5:
    if vernums[0] == 0:
        raise RuntimeError("SciPy v0.5.1 or above is required")

The problem was that the original code didn't check the first version code.
