2020-06-15 18:46:25 +0200 | commented answer | importing hyperbolic geometry modules about binaries : I think I chose the latest one, SageMath-9.0-Installer-v0.6.0.exe I do not remember having to compile anything |

2020-06-15 17:46:18 +0200 | commented answer | importing hyperbolic geometry modules hi Thierry, and thanks a lot for your answer. I installed Sage 9.0 on Windows 10 in the dumbest possible way, by clicking "next" at every opportunity. I guess that answers your last three questions, although I'm not sure I fully understand them ? To install the surface_dynamics package I just used -pip install as suggested on V. Delecroix's web page, and it works just fine, so I thought something might be broken with the hyperbolic geometry package ? |

2020-06-15 12:02:09 +0200 | answered a question | importing hyperbolic geometry modules ps I did install geometry and rings with sage -pip install package_name --user in the sage shell, then restarted Sage, then restarted my computer, and it still says "cannot import name complex_number". What gives ? |

2020-06-15 12:02:09 +0200 | asked a question | importing hyperbolic geometry modules hi everyone, when I type (in SageMath 9.0 Notebook) "from sage.geometry.hyperbolic_space.hyperbolic_point import * ", I get a long answer with bottom line "ImportError: cannot import name complex_number". Thinking it might fix it, I typed "from sage.rings.complex_number import* ", and got again "cannot import name complex_number". Does anyone know a way around this ? thanks in advance Daniel |
