I've been using Anaconda in Window for all my python coding. I've got a few questions:
How do I check all the existing packages/modules I've installed? What commands do I need to type?
How do I install third-party packages, especially those available in pypi? Sometimes when I download some packages like opencv, I just need to copy the file to the folder 'C:\Users\user\Anaconda\Lib\site-packages', and then type 'import cv2' in the ipython console (I'm using Spyder which is included in Anaconda), which is really easy. But more often, when I see some packages in pypi, I need to download the gz file. Inside the folder, there is a setup.py. When I try to run it, I get errors, like the following:
SystemExit: usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...] or: setup.py --help [cmd1 cmd2 ...] or: setup.py --help-commands or: setup.py cmd --help error: no commands supplied
What's wrong? Do I need to unzip the gz file into some specified folders first before running setup.py? Do I need to type any commands or codes in the ipython console?
