Problems on import octant

[wzf1984]

I have install octant occording to
https://code.google.com/p/octant/wiki/installation
I have replaced line in grid.py with
self.libgridgen = np.ctypeslib.load_library('libgridgen', '/usr/local/lib')

However, when I import octant , there are errors:

>>> import octant
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/octant/__init__.py", line 25, in <module>
import grid
File "/usr/local/lib/python2.7/dist-packages/octant/grid.py", line 902
self._libgridgen.gridgen_generategrid2.restype = ctypes.c_void_p
^
IndentationError: unindent does not match any outer indentation level

I would appreciate your help !

Hi,

You probably disrupted the python indentation when commenting a line of the grid.py, which if I remember is a necessary step on the instructions. Make sure all lines in this function are 4 columns from beguining of def statement. You can use an editor with automatic python indentation as well.
My bit of grid.py looks like this:

Code: Select all

    def __init__(self, xbry, ybry, beta, shape, ul_idx=0, \
                 focus=None, proj=None, \
                 nnodes=14, precision=1.0e-12, nppe=3, \
                 newton=True, thin=True, checksimplepoly=True, verbose=False):
        
        self._libgridgen = np.ctypeslib.load_library('libgridgen', '/usr/local/lib')
        print octant.__path__[0]
        #self._libgridgen = np.ctypeslib.load_library('_gridgen', octant.__path__[0])
        
        self._libgridgen.gridgen_generategrid2.restype = ctypes.c_void_p
        self._libgridgen.gridnodes_getx.restype = ctypes.POINTER(ctypes.POINTER(ctypes.c_double))
        self._libgridgen.gridnodes_gety.restype = ctypes.POINTER(ctypes.POINTER(ctypes.c_double))
        self._libgridgen.gridnodes_getnce1.restype = ctypes.c_int
        self._libgridgen.gridnodes_getnce2.restype = ctypes.c_int
        self._libgridgen.gridmap_build.restype = ctypes.c_void_p

The googlecode version of octant is deprecated. You should use the one on github:

https://github.com/hetland/octant

You can download it using the command:

Code: Select all

git clone https://github.com/hetland/octant.git

For this version, I separated out the gridgen stuff, so it should be much easier to install.

p.s. I'll delete the googlecode version, and point to github, as this is not the first time this has happened.
