qiskit包加载问题- _fblas

Question

试图从https://qiskit.org/textbook (https://qiskit.org/textbook/ch-prerequisites/setting-the-environment.html)运行代码，我加载了包，但试图运行它们的示例代码：

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

from qiskit_textbook.widgets import binary_widget

我得到了错误：

E:\PLang\Python37\python.exe D:/Plang/Workspace/QCompDemo/qcAdder.py
Traceback (most recent call last):
  File "D:/Plang/Workspace/QCompDemo/qcAdder.py", line 7, in <module>
    from qiskit import QuantumCircuit, assemble, Aer
  ...
    from .blas import get_blas_funcs
  File "E:\PLang\Python37\lib\site-packages\scipy\linalg\blas.py", line 215, in <module>
    from scipy.linalg import _fblas
ImportError: DLL load failed: The specified module could not be found.

我已经加载了这些：

qiskit                             0.26.2
qiskit-aer                         0.8.2
qiskit-aqua                        0.9.1
qiskit-ibmq-provider               0.13.1
qiskit-ignis                       0.6.0
qiskit-terra                       0.17.4
qiskit-textbook                    0.1.0
mypy                               0.761
mkl                                2021.2.0
scipy                              1.4.1

其他类似的问题报告说，应该安装增强版本的scipy (?)来自(https://www.lfd.uci.edu/~gohlke/pythonlibs/)，但那里有30+版本，不清楚该安装哪个版本。这能解决_fblas动态链接库的问题吗？

嗯；升级到Python 3.8 (从3.7)修复了这个问题。
