Google Colab Notebook raises errors

[ArloMichael]

Hi,

I have been trying to test out this method, specifically in the Google Colab Notebook (https://colab.research.google.com/github/eloimoliner/CQTdiff/blob/main/notebooks/demo.ipynb).

However, it has errors.

Everything was (seemingly) ok up to 'Unconditional Synthesis', which then gave this error:

UFuncTypeError: Cannot cast ufunc 'clip' output from dtype('float64') to dtype('int64') with casting rule 'same_kind'

No further cells worked.

I am not sure if it is something on my end, or something replicable, but it would be great if you could have a look!
