Error in standrad_rb

While running an RB I get the following error:

This is the runcard I am using to launch the experiment:

 - id: standard rb
    priority: 0
    operation: standard_rb
    parameters:
      depths:  
        start: 2
        stop: 20
        step: 1
      niter: 10
      nshots: 100
      unrolling: True 

I am using qibocal, qibolab and qibo in main and qpu156

I am using qibocal, qibolab and qibo in main and qpu156

Which means Qblox, even though the error is apparently already in Qibo.

However, I can tell you immediately which is the problem: you are using NumPy v1, because it was downgraded by your qm-qua installation.
That error is part of the breaking changes between NumPy v1 and v2.

We could wrap that NumPy call ourselves in Qibo, to make it compatible with both versions. But that's not done yet, and it would take some effort to validate the consistent usage of a compatible interface through the whole Qibo code base.
