ValueError: frame_size, frame_overlap not correctly configured

[apiszcz]

I tested 10000 records of random data with frame_size = 50

    138         if not frame_size > 0.0 or not frame_overlap > 0.0 or frame_size < frame_overlap:
    139             raise ValueError(
--> 140                 'frame_size, frame_overlap not correctly configured.')
    141 
    142         # unique time points

ValueError: frame_size, frame_overlap not correctly configured.

Could you please tell me what parameters you used to call the method?

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
from st_dbscan import ST_DBSCAN

# create a 3d data set, e,x,y
df=pd.DataFrame(np.random.random((100000,3)),columns=['e','x','y'])
df=df.sort_values('e')
df.e = (df.e * 86400)+86400

# normalize the data 
df['x'] = (df['x'] - df['x'].min()) / (df['x'].max() - df['x'].min())
df['y'] = (df['y'] - df['y'].min()) / (df['y'].max() - df['y'].min())
# transform to numpy array
data = df.loc[:, ['e','x','y']].values

%%time
st_dbscan.fit_frame_split(data, frame_size = 50)

Can you tell me which version of st_dbscan you are using? I cannot replicate the error. See the screenshot below.

[apiszcz]

0.1.5
Can you place %%time on the first line in cell 4, i'm interested to learn how long this takes. Thank you.

Does this resolve the issue for you?
