问题 To make it more clear, consider a numpy example : import numpy as np from numpy import array This works as expected. But what about this: from np import array The output is: Traceback (most recent call last) <ipython-input-21-d5c81fa93e5f> in <module>() ----> 1 from np import array ModuleNotFoundError: No module named 'np' Once I have set the alias of the imported module numpy as np , shouldn't I be able to import something else using np only? Also, the id() of both is the same -- both numpy

I'm trying to create a basic blogging application in Python using Web.Py. I have started without a direcotry structure, but soon I needed one. So I created this structure: Blog/ ├── Application/ │ ├── App.py │ └── __init__.py | ├── Engine/ │ ├── Connection/ │ │ ├── __init__.py │ │ └── MySQLConnection.py │ ├── Errors.py │ └── __init__.py ├── __init__.py ├── Models/ │ ├── BlogPostModel.py │ └── __init__.py ├── start.py └── Views/ ├── Home.py └── __init__.py start.py imports Application.App , which contains Web.Py stuff and imports Blog.Models.BlogPostModel , which imports Blog.Engine.Connection

I have followed the instructions here , which after installation indicates that the installation is successful (however, there are some warnings. The full log of the install and warnings can be found here ) After running the install, I am trying to run Test.py in the lxml install directory to ensure that it's working correctly. I am immediately prompted with the error: ImportError" cannot import name etree. This error results from the line from lxml import etree . I can't seem to figure out why it's failing here after a

I can't get my jupyter notebook properly import any modules. The weird thing is, I am able to import numpy but not pandas with Sublime.
