B1 | Incorrect Variable name and wrong method #5

Open AlanThinks opened 2 weeks ago

AlanThinks commented 2 weeks ago

In the notebook B1 | First Steps into... , in the last code cell

  1. counts_sample=results_sampler[0].data.meas.get_counts() There is no variable results_sampler

    • PROBABLE FIX: change results_counts[0] to result[0], or simply result depending on the object being returned

  2. It still won't work because it's calling the wrong method on the wrong type of object SamplerPubResult and/or DataBin, not sure.

    • I don't know the fix, need to read documentation further.

    result.data returns a DataBin object, which does not have a meas or get_counts method

install needed for visualization: %pip install qiskit[visualization] matplotlib

Get and plot the results: result = job.result() counts_sampler = result[0].data.c.get_counts()
