ModuleNotFoundError:没有名为“scanpy”的模块(python)

Question

我安装了scanpy，当我检查pip show时，它就在那里了：

C:\Users\plain>pip show scanpy
Name: scanpy
Version: 1.8.2
Summary: Single-Cell Analysis in Python.

但是，当我试图将它导入木星笔记本时，我会收到一条错误消息：

import scanpy as sc
ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-3-0074c9bc0b31> in <module>
----> 1 import scanpy as sc

ModuleNotFoundError: No module named 'scanpy'

有人知道这是为什么吗？

谢谢你的帮助！

在这种情况下，我总是检查Python是否“看到”了我的环境。最简单的方法是打印Pythonpath。在jupyter记事本中运行以下代码，以确保Python知道scanpy安装路径：

import sys
print(sys.path)

您的文件夹c:\users\plain\appdata\local\programs\python\python39\lib\site-packages应该在打印路径中。
