I wanted to try codes from http://csie.nqu.edu.tw/smallko/sdn/dijkstra_ryu.htm but when I try to run the codes, it doesn't work. There always 'ImportError: No module dijkstra_ryu.py' error
I am using Ubuntu 16.04.4 LTS, python 2.7.12 and 3.5.2, and ryu 4.23.
Here's what happen:
ray@raihanr:~/ryu/ryu/app$ ryu-manager dijkstra_ryu.py --observe-links
loading app dijkstra_ryu.py
Traceback (most recent call last):
File "/usr/local/bin/ryu-manager", line 9, in
load_entry_point('ryu==4.23', 'console_scripts', 'ryu-manager')()
File "/usr/local/lib/python2.7/dist-packages/ryu/cmd/manager.py", line 98, in main

mod = utils.import_module(name)
File "/usr/local/lib/python2.7/dist-packages/ryu/utils.py", line 104, in import_module
return importlib.import_module(modname)
File "/usr/lib/python2.7/importlib/init.py", line 37, in import_module
import(name)
ImportError: No module named dijkstra_ryu.py
I also tried using:
ryu/ryu/app$ ryu-manager --observe-links dijkstra_ryu.py
but it keeps showing the same error
Sadly, I also try this:
:~$ryu-manager ryu/ryu/app/dijkstra_ryu.py --observe-links
then a new error shows up
ImportError: Import by filename is not supported.
I already checked every module and not missing any part.
I FOUND IT GUYS. the problem is in the spacing rules. the codes are messy, so we need to make it right for spacing that is 4 times when the codes are inside the definition, for, if, and etc.
