PermissionError: [Errno 13] Permission denied

[danglotb]

Hello,

When I run pyJoules, I have the following error:

PermissionError: [Errno 13] Permission denied: '/sys/class/powercap/intel-rapl/intel-rapl:0/intel-rapl:0:2/energy_uj'

I do not understand what I did to have less permission on these files.

Here, is the output of ls -l:

ls -l /sys/class/powercap/intel-rapl/intel-rapl:0/intel-rapl:0:2 
total 0

Looks quite normal that the permission is denied, because of -r-------- 1 root root 4096 Nov 15 11:10 energy_uj. I do not want to set up the proper permissions manually(e.g. with chmod command), do you have any idea if there are any settings or something I can do to have the proper permissions ?

Thank you.
