# ERROR_RUNNING_JOB with 32 qubit circuit running on ibmq_qasm_simulator backend

I recently made a quantum circuit that uses 32 qubits and try to run it on IBM Q Experience qasm_simulator backend. But it always ends with ERROR_RUNNING_JOB.

When i retrieve the job and display the error, i only got

"The following experiments failed:\n" without any details.

The following is my qiskit version information:

{'qiskit': None, 'qiskit-terra': '0.8.0', 'qiskit-ignis': '0.1.1', 'qiskit-aer': '0.2.0', 'qiskit-ibmq-provider': '0.2.2', 'qiskit-aqua': '0.5.2'}


According to @Bram suggestion i run

$pip install qiskit Building wheels for collected packages: qiskit, qiskit-ibmq-provider Building wheel for qiskit (setup.py) ... error Complete output from command /home/userName/anaconda3/envs/quantum/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-install-kavivdyx/qiskit/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" bdist_wheel -d /tmp/pip-wheel-eak_06_d --python-tag cp37: running bdist_wheel ---------------------------------------- Failed building wheel for qiskit Running setup.py clean for qiskit Building wheel for qiskit-ibmq-provider (setup.py) ... done Stored in directory: /home/userName/.cache/pip/wheels/0c/56/e7/b07b4d2f19fd4c5fff7fe334c72eb313fecf04fa693a7c558e Successfully built qiskit-ibmq-provider Failed to build qiskit Installing collected packages: qiskit-terra, qiskit-aer, nest-asyncio, qiskit-ibmq-provider, pyscf, qiskit-chemistry, qiskit, more-itertools Found existing installation: qiskit-terra 0.8.0 Uninstalling qiskit-terra-0.8.0: Successfully uninstalled qiskit-terra-0.8.0 Found existing installation: qiskit-aer 0.2.0 Uninstalling qiskit-aer-0.2.0: Successfully uninstalled qiskit-aer-0.2.0 Found existing installation: qiskit-ibmq-provider 0.2.2 Uninstalling qiskit-ibmq-provider-0.2.2: Successfully uninstalled qiskit-ibmq-provider-0.2.2 Running setup.py install for qiskit ... done Found existing installation: more-itertools 6.0.0 Uninstalling more-itertools-6.0.0: Successfully uninstalled more-itertools-6.0.0 Successfully installed more-itertools-5.0.0 nest-asyncio-1.0.0 pyscf-1.6.2 qiskit-0.11.0 qiskit-aer-0.2.3 qiskit-chemistry-0.5.0 qiskit-ibmq-provider-0.3.0 qiskit-terra-0.8.2  From this output i notice that wheel was failed in build, does that cause any problems? I then run $conda list | grep qiskit

enter preformatted text here


and run the following in IPython console

>>import qiskit
>>qiskit.__qiskit_version__
Out[2]:
{'qiskit': '0.11.0',

'qiskit-aer': '0.2.3',
'qiskit-ibmq-provider': '0.3.0',
'qiskit-aqua': '0.5.2'}


i will send another job and wait for the result.

Edit: The same error , ERROR_RUNNING_JOB, still occur, appear after the above update.

• Installation is fine, wheel failure is not an problem, Did you try another standard example? ERROR_RUNNING_JOB could also mean a wrong line in youre code. Also the credentials needs to be set. – Bram Jul 21 at 20:29
• @Bram If you mean IBMQ credentials of course i set them. I tried a smaller circuit with 28 qubit and it works without errors. The 32 qubit circuit use another subcircuit that is tested and used in the 28 quibt circuit. – Abdalla Essam Ali Jul 22 at 4:34
• Hi, can you provide some more information about the circuit you are running and the parameters you are using to submit it? – met927 Aug 5 at 11:56
