Class LookupError

Namespace

NumSharp

Assembly

NumSharp.dll

NumPy-compatible LookupError: a name that a registry does not know. NumSharp raises it where Python's codec registry does — an encoding name np.savetxt / np.loadtxt cannot resolve (unknown encoding: bytes: np.savetxt has no special 'bytes' encoding, unlike np.loadtxt).

Remarks

Python's LookupError is the base of KeyError and IndexError; NumSharp's KeyError and IndexError keep their own bases (changing them would break existing catch sites), so this class carries only the codec lookup. It derives from ArgumentException: the unknown name is an argument, and a .NET caller that catches ArgumentException around an encoding choice keeps working.
