Describe the bug
My code is below:

import neurokit2 as nk
import pandas as pd
data1=pd.read_csv("sample.csv", names=["EDA"])
signals, info = nk.eda_process(data1["EDA"], sampling_rate=100, report="report.html")

Output:

The raw signal, sampled at 100 Hz, was cleaned using the default method of the neurokit2 package.

The signal was decomposed into phasic and tonic components using the method described in neurokit.

The cleaned signal was used to detect peaks using the default method of the `neurokit2` package.
