Is debugging available in Jupyter-lab for Sagemath ? Hello everyone, In Jupyter-lab, I can activate the debugger for py

Compile from source fails on Ubuntu I tried to compile sage from source. I did git clone github.com/sagemath/sage.git

Hi there,

When running ./configure to compile sage, it looks for a system install pari/gp in standard system location ( Debian ). I would like to know if there is a way to specify custom location for libpari and for the gp executable. Let say for example I have all pari/gp stuffs ( lib, include, binaries ... ) in the folder /home/myowncompiledpari. I would like to tell sage to use this files and not compile his own version. I tried to write a .pc file specifying locations, but it does not work. I also tried to look into the configure script to see how it look for it, but couldn't find my way out.

Thank you for your help John

Hello,

In the PolyhedronFace class, everything works fine for me except the functions ambient_V_indices and ambient_H_indices. Exemple :

square = polytopes.hypercube(2)
fl = square.face_lattice();

list(f.ambient_V_indices() for f in fl)

I get :

AttributeError                            Traceback (most recent call last)
<ipython-input-3-58aa615735f2> in <module>()
      2 fl = square.face_lattice();fl
      3 
----> 4 list(f.ambient_V_indices() for f in fl)

<ipython-input-3-58aa615735f2> in <genexpr>((f,))
      2 fl = square.face_lattice();fl
      3 
----> 4 list(f.ambient_V_indices() for f in fl)

AttributeError: 'PolyhedronFace' object has no attribute 'ambient_V_indices'

Other methods work fine:

simplex = polytopes.simplex(3)
     for face in simplex.faces(2):
          print face.as_polyhedron()
          print face.dim()
          print face.vertices()

work perfectly.

When I deal with a polyhedron face, I would really like to get corresponding vertices indices in the parent polyhedron via "ambient" methodes. How can I fix this ?

Thanks a lot
