Matplotlib issue #440

Closed Rahi63 closed 1 year ago

Rahi63 commented 2 years ago

Hello, I am new to SDN and Mininet. Could you please guide me on how to solve this problem? Thank you

sudo mn --wifi [sudo] password for lab1:

This is not a mac80211_hwsim issue. One of the messages say: 

You probably need to get an updated matplotlibrc file from
[http://github.com/matplotlib/matplotlib/blob/master/matplotlibrc.template](https://github.com/matplotlib/matplotlib/blob/master/matplotlibrc.template)
or from the matplotlib source distribution

What should you do??

Rahi63 commented 2 years ago

Thank you for your response. I executed this command first: sudo apt-get install linux-image-extra-uname -r

but I got an error:

sudo apt-get install linux-image-extra-$(uname -r) Reading package lists... Done Building dependency tree
Reading state information... Done E: Unable to locate package linux-image-extra-5.13.0-41-generic E: Couldn't find any package by glob 'linux-image-extra-5.13.0-41-generic' E: Couldn't find any package by regex 'linux-image-extra-5.13.0-41-generic'

and then, according to another topic (error in loading mac80211_hwsim #169), I applied the commends, but the problem was not solved.

Did you solve the problem with matplotlib??

Rahi63 commented 2 years ago

Not yet. I don't know how should I update matplotlibrc file because the link that you sent me doesn't work.

ramonfontes commented 2 years ago

Pardon, which link I sent to you? Wasn't it issued by your system??

Rahi63 commented 2 years ago

I updated matplotlibrc file but I got an error when I ran my topology:

Warning! If you already had Mininet-WiFi installed please run util/install.sh -W and then sudo make install. Warning! Error when loading mac80211_hwsim. Please run sudo 'mn -c' before running your code. Further information available at /tmp/mn-wifi-mac80211_hwsim.log.

ramonfontes commented 2 years ago

What is the result for sudo modprobe mac80211_hwsim?

Rahi63 commented 2 years ago

nothing. lab1@ubuntu:~$ sudo modprobe mac80211_hwsim lab1@ubuntu:~$

after that when I run: sudo mn --wifi I get the same error arning! Error when loading mac80211_hwsim. Please run sudo 'mn -c' before running your code

ramonfontes commented 2 years ago

Please copy here the outcome for sudo mn --wifi -v debug

Please fix the error with matplotlib

Rahi63 commented 2 years ago

first: I installed successfully following files: pip install matplotlib==2.1.0

then: sudo pip install matplotlib sudo pip install numpy sudo pip install scipy

but I got an error again.

I tried everything I knew and you said, could you please guide me on how I should update matplotlib?
