Se eliminó la función de un módulo en interactivo. ¿Cómo volver a importar? importlib.reload no ayuda
He eliminado una función (paquete integrado) en ipython:
Python 3.6.4 |Anaconda custom (64-bit)| (default, Jan 16 2018, 10:22:32) [MSC v.1900 64 bit (AMD64)]
Type 'copyright', 'credits' or 'license' for more information
IPython 6.2.1 -- An enhanced Interactive Python. Type '?' for help.
In [1]: import math
In [2]: math.cos(0)
Out[2]: 1.0
In [3]: del math.cos
In [4]: math.cos(0)
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-4-9cdcc157d079> in <module>()
----> 1 math.cos(0)
AttributeError: module 'math' has no attribute 'cos'
OKAY. Pero, ¿cómo recargo la función? Esto no ayudó:
In [5]: import importlib
In [6]: importlib.reload(math)
Out[6]: <module 'math' (built-in)>
In [7]: math.cos(0)
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-7-9cdcc157d079> in <module>()
----> 1 math.cos(0)
