我跑了这个

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

并得到以下错误

任何想法？

我安装了 numpy 1.16/1.17 和最新的，还是一样的错误。
python - 3.7.9 我运行 ML 项目，所以版本至关重要

这是因为最新的 Qiskit Aer（0.7.4，Qiskit meta 0.23.5）是用 numpy 1.20.0 编译的，与旧版本的 numpy 不兼容。有关更多详细信息，请参阅此问题：https ://github.com/Qiskit/qiskit-aer/issues/1120 。

目前的解决方法是将您的 numpy 升级到 1.20.0。

看起来您的安装以某种方式损坏了。您是否尝试重新安装？

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