Measurements error

[manceaur]

I tried to run a simple following example with pyRAPL but something went wrong when measurement ends :

I'm using Fedora 35, python 3.9.12

Here the code :

import pyRAPL

pyRAPL.setup()

csv_output = pyRAPL.outputs.CSVOutput('results.csv')

@pyRAPL.measureit(output=csv_output)
def test(N):
    a = 0
    for i in range(N):
        a += 1
    return a

test(1000)

csv_output.save()

TypeError                                 Traceback (most recent call last)
~/test_measurement.ipynb Cellule 6 in <cell line: 14>()
     [11]        a += 1
     [12]    return a
---> [14] test(1000)
     [17] csv_output.save()

     54 return Result(self.label, self.timestamp, _duration, _pkg, _dram)
