Crashed on quick start example

import ComputationalHypergraphDiscovery as CHD
import pandas as pd
df=pd.read_csv('https://raw.githubusercontent.com/TheoBourdais/ComputationalHypergraphDiscovery/main/examples/SachsData.csv')
kernels=CHD.Modes.LinearMode()+CHD.Modes.QuadraticMode()
graph_discovery = CHD.GraphDiscovery.from_dataframe(df,mode_kernels=kernels)
graph_discovery.fit()
graph_discovery.plot_graph()

With Python 3.10.12, I get:

Pyarrow will become a required dependency of pandas in the next major release of pandas (pandas 3.0),
(to allow more performant data types, such as the Arrow string type, and better interoperability with other libraries)
but was not found to be installed on your system.

Hi Nicolas,

I do not think this is an issue with the code itself rather a Pandas issue. This seems to be a problem with your installation of Pandas

I ran the above script with the debugger. The crash happens at this line:

https://github.com/TheoBourdais/ComputationalHypergraphDiscovery/blob/main/src/ComputationalHypergraphDiscovery/Modes/kernels.py#L250

In the debugger, I see that crash happens when Python attempts to invoke the '*' operation in the expression:

np.expand_dims(linear_mat, 0) * np.expand_dims(linear_mat, 1)

Does this help?
