20211022 02:45:11 +0200  marked best answer  A problem with fast_callable I am having a problem with getting consistent results from fast_callable (Sagemath 9.2). Consider the following example: The result of the first print is [2. 4.] as expected but the result of the second print is just 0.0 instead of [0.0,0.0]. In my real application coords dynamically changes, and becuase of this I have to check whether a compomnant is constant or not before applying fast_callable.

There are several consequences to this, for example, the stored path cannot be fed again to bezier_path, so this won't work (results in weird errors): and also affects the plot3d method of the class. The issue seems to stem from line 64 of bezier_path.py: Since the list of vertices changes size after the line so does self.path. I believe the line should be

In 2d this simply works: But when I want to plot it in 3d, this line or both give me the following error: TypeError: unable to convert (t  1)^3 to an integer. What am I doing wrong?
