Error appears doing Rabi

Hi @rodolfocarobene, I am trying to run a Rabi in 2 qubits at the same time and I get this error

I am using the branch javi/spinq10q_12_zcu111 on qibolab_platforms_qrc and the action card is

targets: [2,3]

format: csv
actions:
  - id: rabi
    priority: 0
    operation: rabi_amplitude
    # main: single shot classification
    parameters:

Please try to update qibosoq/qibolab at the latest version and tell me if the problem still appear. I see that the error is in

 File "/home/xilinx/qibosoq/src/qibosoq/programs/base.py", line 291, in collect_shots
    tot.append(stacked[:, idx].reshape(shape).tolist())

but in main this is in line 294, so maybe I already did some fix for this.

@rodolfocarobene , I have reinstall qibolab/qibosoq in the board and in Saadiyat but still I get the error in line 294

Good, so it means it is indeed a bug! You should try to run pulse shapes test in order to see which types are affected: https://github.com/qiboteam/qibolab/blob/main/tests/test_result_shapes.py

I am not sure when I will be able to try this
