KeyError: 'method' when running on dataset

[eliwagnercode]

Hello, I'm having the same problem as was described in this issue that was closed on 2023.01.15, but I am using the latest version of pyVHR (2.0):
#48

When I run the following code I get a naming warning and an error:

`from pyVHR.analysis.pipeline import Pipeline, DeepPipeline
from pyVHR.analysis.stats import StatAnalysis
from pyVHR.plot.visualize import *
import os
import pandas as pd
import plotly.express as px
from numpy import round as r
import plotly.io as pio
pio.renderers.default = 'jupyterlab'

path_h5 = '../results/h5/UBFC2_holistic.h5'
path_cfg = '../results/cfg/UBFC2_holistic.cfg'

pl = Pipeline()
res = pl.run_on_dataset(path_cfg, verb=1)
res.saveResults(path_h5)
print('Written file: ' + path_h5 + '\n\n')

st = StatAnalysis(path_h5)
fig = st.displayBoxPlot(metric='MAE', scale='log')
fig.show()`

** Run the test with the following config:
dataset: UBFC2
methods: ['CHROM', 'POS', 'LGI', 'ICA', 'PCA']

CUDA devices: 2

device number 0 : NVIDIA RTX A4000

device number 1 : NVIDIA RTX A4000

• cuda device: True
• skin extractor: convexhull
• ROI approach: holistic

The above exception was the direct cause of the following exception:

KeyError: 'method'

I'm not understanding if this is an issue with the package itself or how my environment is set up, or how I defined the filepath to the cfg and h5 files. Thanks in advance for any guidance you can provide!
