蟒蛇激活失败

Question

基本上就是标题所说的。这是 cmd 的一个片段：

C:\Users\Marc>conda activate quantum

(quantum) C:\Users\Marc>py
Python 3.8.5 (default, Sep  3 2020, 21:29:08) [MSC v.1916 64 bit (AMD64)] :: Ana
conda, Inc. on win32

Warning:

>>> from qiskit import QuantumCircuit
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name 'QuantumCircuit' from 'qiskit' (unknown location
)
>>>

尽管我运行了激活环境的命令 (conda activate quantum)，但仍然如此。基本环境确实有效，但我想激活另一个环境。 对于那些好奇的人，Anaconda navigator 和 pip freeze 都表明 qiskit 安装在这个环境中。

我意识到了我的错误。我应该输入 print(df) PE Change 0 38.31 -0.06 来启动解释器。
