HI! I, Jaekwook Lee, am a graduate student at Chungbuk National university, Korea, and am currently working on particle trajectory around black holes.
The error source is SageManifolds / Notebooks / Image of an accretion disk around a Schwarzschild black hole. (Black hole rendering with SageMath / Florentin Jaffredo)
The error occur in Cell Number [38] and [39] as below
AttributeError Traceback (most recent call last)
