ValueError: numpy.ndarray size changed on importing qiskit

Question

While trying to run the following commands on Jupyter

from qiskit import QuantumCircuit, Aer, BasicAer, execute
from qiskit.visualization import plot_histogram

I am encountering the following error.I am using python 3.8. Does anyone have any idea how can this be resolved? I have tried upgrading numpy and reinstalling Qiskit but the problem prevails

ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject

Answer 1

worked after I used the following command

pip install --ignore-installed qiskit-terra qiskit-aer
