Error on running short code #7

Closed AR3S-Vega closed 1 year ago

AR3S-Vega commented 2 years ago

Here is the short code. I just want to generate some QRNGs for a small project.

import qrng

for i in range(100):
    print(qrng.get_random_int(0,9))

Traceback (most recent call last): File "C:\Users[USER]\Documents\python\qrngarraymakaer.py", line 4, in print(qrng.get_random_int(0,9)) File "C:\Users[USER]\AppData\Local\Programs\Python\Python37\lib\site-packages\qrng__init.py", line 77, in get_random_int result = int(get_bit_string(n),2) File "C:\Users[USER]\AppData\Local\Programs\Python\Python37\lib\site-packages\qrng__init__.py", line 67, in get_bit_string _request_bits(n-len(_bitCache)) File "C:\Users[USER]\AppData\Local\Programs\Python\Python37\lib\site-packages\qrng\init__.py", line 60, in _request_bits job = qiskit.execute(_circuit, _backend, shots=1) NameError: name '_backend' is not defined

Before generating random numbers, you need to set the backend. Please refer to the tutorial.
