hi

how to fix following error?

best

[ramonfontes]

The error means that you haven't installed all the mn-wifi dependencies. Please make sure that you have installed mn-wifi successfully.

[mfatihkoc]

I follow here what else to follow the mininetwifi dependency then

https://github.com/ramonfontes/mn-wifi-ebook/blob/main/beginner.md

[mfatihkoc]

my mininet wifi version is 2.6

[mfatihkoc]

• ~/mininet-wifi$ git clone https://github.com/ramonfontes/reproducible-research
• ~/mininet-wifi$ sudo rm -r /usr/local/lib/python2.7/dist-packages/mininet*
• ~/mininet-wifi$ git reset --hard b43af65
• ~/mininet-wifi$ sudo make install
• ~/mininet-wifi$ cd reproducible-research/mininet-wifi/IEEE-Access-2017
• ~/mininet-wifi/reproducible-research/mininet-wifi/IEEE-Access-2017$ sudo python vanet.py

from

https://github.com/ramonfontes/reproducible-research/blob/master/mininet-wifi/IEEE-Access-2017/README.md

I am in the mininet-wifi folder and I follow above Reproducibility steps many times. cloned and deleted de to errors. are you sure this are updated?

[ramonfontes]

make install will only work if you have mininet-wifi installed.

By the way, it seems to me that you are using python3. The code in 2017 was prepared for python2.

[mfatihkoc]

Python 2.7.18 dowloaded now.

ImportError: No module named matplotlib.pyplot occuring, I am not sure that I need to dowload again this modules or what to do?

you have not updated with the current versions these code scripts? are you able to run by 2024 this codes?

[ramonfontes]

you have not updated with the current versions these code scripts?

Why would I do that? I can't check every code I produce.

are you able to run by 2024 this codes?

Yes if I have all dependencies satisfied.

[mfatihkoc]

from mininet.node import Controller, OVSKernelSwitch, OVSKernelAP, Car ImportError: cannot import name 'OVSKernelAP' from 'mininet.node' (/usr/local/lib/python3.10/dist-packages/mininet/node.py)

this is regarding OVSKernelAP error

so should I UPDATE the code to the python 3 way or is that posible to run with python2 but with this I see errors of modules

[ramonfontes]

You have to run the code as it is. However, you have to solve the issues with dependencies. There is no point in sending screenshots of missing dependencies when the error msg is already there. It already says what you should do: install matplotlib with pyplot support.

[mfatihkoc]

I send because my matplotlib is already running with python3 itself easly with another simple example of python where I tested with different code, however running with python2 is problematic.
