Thanks for this issue and sorry you are running into this.

Looks like your kernel crashed while running a cell, probably the 18th cell
We have seen this happens a lot when packages such as PyTorch/Tensorflow or the like are not correctly installed and causes the kernel to crash when those packages are imported/used in some form.

Please could you check what code is executed in the 18th cell, optionally please try to isolate the code that causes the kernel to crash and try to figure out what in that code/package could be causing the kernel to crash.

[fevc08]

This is the code:
data_prices = ds_nona['price']
bins = np.arange(min(data_prices), max(data_prices) + 1, 1)

x = ds_nona.loc[ds_nona['level5'] == 'Arroyomolinos (Madrid)']

plt.hist(x['price'], bins)
plt.xlabel('Frecuancy')
plt.ylabel('Prices')
plt.title('Prices of Population Arroyomolinos (Madrid)')
plt.show()

but I can't isolate it,

[DonJayamanne]

but I can't isolate it,

Does the kernel crash if you do not run the above cell?
If not, then there's a problem with the package numpy or the like

You might want to try this outside VS Code or reach out to stackover flow or the like, as this is most likely not an issue with VS Code as you seem to be able to run other cells.

Sorry I cannot help you figure out what is going on.

[fevc08]

Yes, all the code above run but when I try to run that part the kernel crash.

But thank you, I will try something else
