Hi,

I have a load data problem.

code has an error:import numpy as np  
import pandas as pd

# 1) Charger fichier

data = pd.read\_csv(“Neuro2025\_005\_2025\_11\_25\_Marker.txt”, sep=‘\t’, header=None)

# 2) Reshape en (time, 23 marqueurs, XYZ)

reshaped\_data = data.values.reshape(-1, 23, 3)

# 3) Créer MultiIndex correct

Marker\_columns = [f’M{i}’ for i in range(1, 24)] # 23 marqueurs  
coordinate\_columns = [‘X’, ‘Y’, ‘Z’]

columns = pd.MultiIndex.from\_product(  
[Marker\_columns, coordinate\_columns],  
names=[‘Marker’, ‘Coordinate’]  
)

# 4) Créer DataFrame final

reshaped\_df = pd.DataFrame(  
reshaped\_data.reshape(-1, 23 \* 3),  
columns=columns  
)

#print(reshaped\_df.head())

print(data.head())  
print(data.tail())  
print(data.shape)

Data form is

Have you tried running this with Python without involving Jupyter? I suspect you’d get the same result, which means it is likely not a Jupyter issue and therefore this is not pertinent to this forum.

The big issue for wherever you end up posting is that you say it has an error and there is no error provided.

Please read and use [Getting good answers to your questions](https://discourse.jupyter.org/t/getting-good-answers-to-your-questions/1825) as a guide to posting in this forum and related ones.  
And please look at other examples of posted code here. You want to make it so others can just paste it in and run it. To help you with that see about ‘block code formatting’ [here](https://meta.discourse.org/t/post-code-or-preformatted-text/188910#block-code-formatting-6). (Or see about ‘fenced code blocks’ [here](https://meta.stackoverflow.com/a/251362/8508004). They are both the same thing if you look into the details.
