问题 I'm using python and virtualenv/pip. I have a module installed via pip called test_utils (it's django-test-utils). Inside one of my django apps, I want to import that module. However I also have another file test_utils.py in the same directory. If I go import test_utils , then it will import this local file. Is it possible to make python use a non-local / non-relative / global import? I suppose I can just rename my test_utils.py , but I'm curious. 回答1: You can switch the search order by

问题 Python newbie here. Any and all help on python structure would be much appreciated! MAIN QUES: How to Import Multiple Python Modules from Other Directories I've reassembled the repository for a project so that modules for specific tasks are within individual folders according to type of task instead of just one huge folder. Because my modules were all in one folder, I used to be able to import easily in this fashion: import sys sys.path.insert(0,'/home/myname/folder_name/all_modules') Now, I

问题 I'm having trouble understanding how objects declared inside '__init__.py' are/should be imported to other files. I have a directory structure like so top/ | |_lib/ |_ __init__.py |_ one.py File contents are as follows lib/__init__.py a=object() lib/one.py from lib import a Here is the problem.

问题 I currently work with keras and custom activation functions. I store those models as pickle and I would like to be able to load them again. Then I run into this issue. The problem is that the Python script which contains the custom activation function is given by path. I load this script via import imp model_module = imp.load_source('model', experiment_meta['model']['script_path']) How can I "star import" ( import * ) in this case to make the loading of the trained model work? What I've tried

问题 I have installed python 2.6.6 and python 2.5.5 on the same machines (Ubuntu 10.0.4), since 2.6 is my default version and 2.5 I need for maintaining old stuff.

Is there a way to tell for which version module should be installed? Thanks in advance 回答1: You can use easy_install . To use it for particular version, you just
