Running Algorithm on ibmqx5 DAG Circuit error about qiskit-tutorials HOT 11 CLOSED

Hi, thanks reporting this issue.

I also found a similar issue and am thinking that it may be caused by the mapper.
I have raised the issue here:
Qiskit/qiskit#492

By the way, please update your qiskit to the latest version by pip install -U qiskit.

from qiskit-tutorials.

Thank You @rraymondhp now ay get similar error as
https://github.com/rraymondhp/qiskit-tutorial/blob/ba1d80923fc02234f1fadda7be996bdd6fb4c712/reference/algorithms/grover_algorithm.ipynb
says
qiskit.mapper._mappererror.MapperError: 'initial_layout qubit qin[15] not in input DAGCircuit'

Hi @amantamirat
There is a bug when using two or more quantum registers with different names. It will be fixed on the next release.

from qiskit-tutorials.

Hi @amantamirat
The bug with multiple registers has been fixed with version 0.5.3
Please update your qiskit-sdk-py by pip install -U qiskit.

Meanwhile, I have updated the tutorial for Grover search as the link below:

@rraymondhp can we close

Thanks. Yes, it is solved.

Hello beautiful people sorry for lost , DAG circuit now is not the problem but this
qiskit._qiskiterror.QISKitError: '"{'message': 'Error parsing QASM. Error parsing qasm number 0.', 'statusCode': 400, 'status': 400, 'code': 'QASM_NOT_VALID'}"'
the code works fine in any simulator devices but when i try to run on real Quantum device it give me this Error

Hello,
Have you updated qiskit to be the latest (version 0.5.6)?

from qiskit-tutorials.

yes I have updated, but still the same error message!!!!!

Hi @amantamirat
I succeeded to run the program, so I guess I need to know more of your program.
Below is the link to my program:

https://github.com/rraymondhp/qiskit-tutorial/blob/rr-v56-grover/reference/algorithms/grover_algorithm.ipynb

from qiskit-tutorials.

Hello: my program is a Grover algorithm that searches from array but when i increase the size of the array the error is occurred .technically in ibm simulator no more than 8 elements i.e. 3 iteration and for ibmx5 is only 2 iterations are working beyond this size it is not working !!
