In order to avoid the problem posted in Why "job_manager" did not submit some of the jobs?, (the current issue is related but quite different, so I think it is more appropriate to ask separately), I divide the job to batches, with each batch having 75*5=375 circuits. Then I use ("item" below contains a list of 375 circuits)
job_set = job_manager.run(item, backend=backend, name='L_5_vqe_qc' , shots = 8192 )
with the hope that "job_mamager" will submit the 5 jobs, each with 75 circuits. However, it turns out that the same job was submitted twice. See the screenshot below, where "L_5_vqe_qc_2" was submitted twice. Is this normal?
